Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”

What this handout is about

This handout will help you understand how paragraphs are formed, how to develop stronger paragraphs, and how to completely and clearly express your ideas.

What is a paragraph?

Paragraphs are the building blocks of papers. Many students define paragraphs in terms of length: a paragraph is a group of at least five sentences, a paragraph is half a page long, etc. In reality, though, the unity and coherence of ideas among sentences is what constitutes a paragraph. A paragraph is defined as “a group of sentences or a single sentence that forms a unit” (Lunsford and Connors 116). Length and appearance do not determine whether a section in a paper is a paragraph. For instance, in some styles of writing, particularly journalistic styles, a paragraph can be just one sentence long. Ultimately, a paragraph is a sentence or group of sentences that support one main idea. In this handout, we will refer to this as the “controlling idea,” because it controls what happens in the rest of the paragraph.

How do I decide what to put in a paragraph?

Before you can begin to determine what the composition of a particular paragraph will be, you must first decide on an argument and a working thesis statement for your paper. What is the most important idea that you are trying to convey to your reader? The information in each paragraph must be related to that idea. In other words, your paragraphs should remind your reader that there is a recurrent relationship between your thesis and the information in each paragraph. A working thesis functions like a seed from which your paper, and your ideas, will grow. The whole process is an organic one—a natural progression from a seed to a full-blown paper where there are direct, familial relationships between all of the ideas in the paper.

The decision about what to put into your paragraphs begins with the germination of a seed of ideas; this “germination process” is better known as brainstorming . There are many techniques for brainstorming; whichever one you choose, this stage of paragraph development cannot be skipped. Building paragraphs can be like building a skyscraper: there must be a well-planned foundation that supports what you are building. Any cracks, inconsistencies, or other corruptions of the foundation can cause your whole paper to crumble.

So, let’s suppose that you have done some brainstorming to develop your thesis. What else should you keep in mind as you begin to create paragraphs? Every paragraph in a paper should be :

• Unified : All of the sentences in a single paragraph should be related to a single controlling idea (often expressed in the topic sentence of the paragraph).
• Clearly related to the thesis : The sentences should all refer to the central idea, or thesis, of the paper (Rosen and Behrens 119).
• Coherent : The sentences should be arranged in a logical manner and should follow a definite plan for development (Rosen and Behrens 119).
• Well-developed : Every idea discussed in the paragraph should be adequately explained and supported through evidence and details that work together to explain the paragraph’s controlling idea (Rosen and Behrens 119).

How do I organize a paragraph?

There are many different ways to organize a paragraph. The organization you choose will depend on the controlling idea of the paragraph. Below are a few possibilities for organization, with links to brief examples:

• Narration : Tell a story. Go chronologically, from start to finish. ( See an example. )
• Description : Provide specific details about what something looks, smells, tastes, sounds, or feels like. Organize spatially, in order of appearance, or by topic. ( See an example. )
• Process : Explain how something works, step by step. Perhaps follow a sequence—first, second, third. ( See an example. )
• Classification : Separate into groups or explain the various parts of a topic. ( See an example. )
• Illustration : Give examples and explain how those examples support your point. (See an example in the 5-step process below.)

Illustration paragraph: a 5-step example

From the list above, let’s choose “illustration” as our rhetorical purpose. We’ll walk through a 5-step process for building a paragraph that illustrates a point in an argument. For each step there is an explanation and example. Our example paragraph will be about human misconceptions of piranhas.

Step 1. Decide on a controlling idea and create a topic sentence

Paragraph development begins with the formulation of the controlling idea. This idea directs the paragraph’s development. Often, the controlling idea of a paragraph will appear in the form of a topic sentence. In some cases, you may need more than one sentence to express a paragraph’s controlling idea.

Controlling idea and topic sentence — Despite the fact that piranhas are relatively harmless, many people continue to believe the pervasive myth that piranhas are dangerous to humans.

Step 2. Elaborate on the controlling idea

Paragraph development continues with an elaboration on the controlling idea, perhaps with an explanation, implication, or statement about significance. Our example offers a possible explanation for the pervasiveness of the myth.

Elaboration — This impression of piranhas is exacerbated by their mischaracterization in popular media.

Step 3. Give an example (or multiple examples)

Paragraph development progresses with an example (or more) that illustrates the claims made in the previous sentences.

Example — For example, the promotional poster for the 1978 horror film Piranha features an oversized piranha poised to bite the leg of an unsuspecting woman.

Step 4. Explain the example(s)

The next movement in paragraph development is an explanation of each example and its relevance to the topic sentence. The explanation should demonstrate the value of the example as evidence to support the major claim, or focus, in your paragraph.

Continue the pattern of giving examples and explaining them until all points/examples that the writer deems necessary have been made and explained. NONE of your examples should be left unexplained. You might be able to explain the relationship between the example and the topic sentence in the same sentence which introduced the example. More often, however, you will need to explain that relationship in a separate sentence.

Explanation for example — Such a terrifying representation easily captures the imagination and promotes unnecessary fear.

Notice that the example and explanation steps of this 5-step process (steps 3 and 4) can be repeated as needed. The idea is that you continue to use this pattern until you have completely developed the main idea of the paragraph.

Step 5. Complete the paragraph’s idea or transition into the next paragraph

The final movement in paragraph development involves tying up the loose ends of the paragraph. At this point, you can remind your reader about the relevance of the information to the larger paper, or you can make a concluding point for this example. You might, however, simply transition to the next paragraph.

Sentences for completing a paragraph — While the trope of the man-eating piranhas lends excitement to the adventure stories, it bears little resemblance to the real-life piranha. By paying more attention to fact than fiction, humans may finally be able to let go of this inaccurate belief.

Finished paragraph

Despite the fact that piranhas are relatively harmless, many people continue to believe the pervasive myth that piranhas are dangerous to humans. This impression of piranhas is exacerbated by their mischaracterization in popular media. For example, the promotional poster for the 1978 horror film Piranha features an oversized piranha poised to bite the leg of an unsuspecting woman. Such a terrifying representation easily captures the imagination and promotes unnecessary fear. While the trope of the man-eating piranhas lends excitement to the adventure stories, it bears little resemblance to the real-life piranha. By paying more attention to fact than fiction, humans may finally be able to let go of this inaccurate belief.

Troubleshooting paragraphs

Problem: the paragraph has no topic sentence.

Imagine each paragraph as a sandwich. The real content of the sandwich—the meat or other filling—is in the middle. It includes all the evidence you need to make the point. But it gets kind of messy to eat a sandwich without any bread. Your readers don’t know what to do with all the evidence you’ve given them. So, the top slice of bread (the first sentence of the paragraph) explains the topic (or controlling idea) of the paragraph. And, the bottom slice (the last sentence of the paragraph) tells the reader how the paragraph relates to the broader argument. In the original and revised paragraphs below, notice how a topic sentence expressing the controlling idea tells the reader the point of all the evidence.

Original paragraph

Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. If the fish are well-fed, they won’t bite humans.

Revised paragraph

Although most people consider piranhas to be quite dangerous, they are, for the most part, entirely harmless. Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. If the fish are well-fed, they won’t bite humans.

Once you have mastered the use of topic sentences, you may decide that the topic sentence for a particular paragraph really shouldn’t be the first sentence of the paragraph. This is fine—the topic sentence can actually go at the beginning, middle, or end of a paragraph; what’s important is that it is in there somewhere so that readers know what the main idea of the paragraph is and how it relates back to the thesis of your paper. Suppose that we wanted to start the piranha paragraph with a transition sentence—something that reminds the reader of what happened in the previous paragraph—rather than with the topic sentence. Let’s suppose that the previous paragraph was about all kinds of animals that people are afraid of, like sharks, snakes, and spiders. Our paragraph might look like this (the topic sentence is bold):

Like sharks, snakes, and spiders, piranhas are widely feared. Although most people consider piranhas to be quite dangerous, they are, for the most part, entirely harmless . Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. If the fish are well-fed, they won’t bite humans.

Problem: the paragraph has more than one controlling idea

If a paragraph has more than one main idea, consider eliminating sentences that relate to the second idea, or split the paragraph into two or more paragraphs, each with only one main idea. Watch our short video on reverse outlining to learn a quick way to test whether your paragraphs are unified. In the following paragraph, the final two sentences branch off into a different topic; so, the revised paragraph eliminates them and concludes with a sentence that reminds the reader of the paragraph’s main idea.

Although most people consider piranhas to be quite dangerous, they are, for the most part, entirely harmless. Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ first instinct is to flee, not attack. Their fear of humans makes sense. Far more piranhas are eaten by people than people are eaten by piranhas. A number of South American groups eat piranhas. They fry or grill the fish and then serve them with coconut milk or tucupi, a sauce made from fermented manioc juices.

Problem: transitions are needed within the paragraph

You are probably familiar with the idea that transitions may be needed between paragraphs or sections in a paper (see our handout on transitions ). Sometimes they are also helpful within the body of a single paragraph. Within a paragraph, transitions are often single words or short phrases that help to establish relationships between ideas and to create a logical progression of those ideas in a paragraph. This is especially likely to be true within paragraphs that discuss multiple examples. Let’s take a look at a version of our piranha paragraph that uses transitions to orient the reader:

Although most people consider piranhas to be quite dangerous, they are, except in two main situations, entirely harmless. Piranhas rarely feed on large animals; they eat smaller fish and aquatic plants. When confronted with humans, piranhas’ instinct is to flee, not attack. But there are two situations in which a piranha bite is likely. The first is when a frightened piranha is lifted out of the water—for example, if it has been caught in a fishing net. The second is when the water level in pools where piranhas are living falls too low. A large number of fish may be trapped in a single pool, and if they are hungry, they may attack anything that enters the water.

In this example, you can see how the phrases “the first” and “the second” help the reader follow the organization of the ideas in the paragraph.

Improve Your Paper by Writing Structured Paragraphs

In academic writing, effective paragraphs serve as building blocks to construct a complex analysis or argument. Paragraphing helps readers to understand and process your ideas into meaningful units of thought.

What do paragraphs do?

Imagine reading this page without paragraph breaks. Paragraphs create order and logic by helping your reader recognize the boundaries where one point ends and another begins.

How long should a paragraph be?

In a first draft, it may make sense to set a goal for length. For example, you can set a goal of writing four to six sentences per paragraph: in that number of sentences you can announce an idea, prove that idea with evidence, and explain why this evidence matters by linking it to the overall goal of your paper.

In the final version of your paper you may have a shorter paragraph or two. Short paragraphs call a lot of attention to themselves, so they can effectively emphasize a point. Too many short paragraphs, however, may indicate that your ideas are not developed with evidence and analysis.

You’ll generally read and write longer paragraphs in academic papers. However, too many long paragraphs can provide readers with too much information to manage at one time. Readers need planned pauses or breaks when reading long complex papers in order to understand your presented ideas. Remember this writing mantra: “Give your readers a break!” or “Good paragraphs give one pause!”

Kinds of sentences in a paragraph

Thinking about paragraphs rigidly in terms of length may lead to formulaic writing. Instead, as you revise your draft think about how each sentence is functioning in your paragraph, and whether your paragraph has sufficient functional sentences to make its point.

Transition sentences guide your reader smoothly from the topic of the preceding paragraph into the topic of your new paragraph. Writers sometimes begin with a transition sentence before introducing the topic of the new paragraph.

A topic sentence states the main idea of a paragraph. Beginning a paragraph with a topic sentence ensures your reader recognizes early in the paragraph what larger idea the paragraph is going to demonstrate. Expert writers may not introduce the topic until the middle or end of the paragraph, and often imply their topics without ever writing a topic sentence.

Body sentences develop the topic of the paragraph. These sentences work to analyze data or quotations, describe a text or event, set up a comparison, showcase evidence, and sometimes they enumerate the logical points for readers to give them a sense of a paper’s bigger picture. In body sentences, you need to consider how much quoted data or evidence will demonstrate or prove your point.

Linking sentences relate back to the paper’s main argument by showing how the idea of that paragraph matches the overall goal of the paper.

Concluding sentences may bring a section to its end before you move on to a new section of the paper.

Some sample paragraphs

Undergraduate art analysis.

Notice how the writer develops the idea in the body sentences, as promised in the first sentence, and concludes her paragraph by offering a keen, close observation of specific details.

In order to understand how Manet’s work echoes or communicates with Titian’s, one must first consider the similarities between their paintings. To begin with, both take a nude woman as the subject. More than that, however, Manet directly copies the composition of Titian’s Venus; the overwhelming similarity in color and the figures’ arrangement in each painting prove this. Both women are lying in the same position with their heads on the left-hand side of the canvas. Both women have their left leg crossed over the right. Both women have flowers and accessories. Other key elements unite these paintings, as well: the arrangement of the sheets on the bed; the green curtains; the servants; and the small animal at the foot of the bed. All these features clearly indicate that Manet echoes Titian. If one stopped at the similarity in the composition, it would appear that both paintings communicate the same thing; both would be a celebration of the beauty of the human figure, and Manet’s voice would have added nothing new to the conversation; it would have no additional meaning besides venerating the masterful work of Titian. ( Used with permission .)

Undergraduate literary analysis

In this paragraph from a 2012 Lewis Prize-winning English essay, UW–Madison undergraduate Abby Becker organizes her sentences savvily. She first transitions her reader into her topic, then introduces the source of evidence for that paragraph before analyzing that source and returning to the topic with the new critical perspective that her analysis suggests.

In order for a political or social revolution to occur, connections must be formed. More means of communication lead to more opportunities to make connections. In Dos Passos’ The 42nd Parallel, J. Ward Moorehouse focuses on making business connections but never forms any relationships. He explains at a party that “he had come down in a purely unofficial way you understand to make contacts” (249). In business and politics, making contacts denotes an impersonal, removed way of dealing with people. This type of communication does not result in connections. Moorehouse’s connections are for his own political personal gain. There may be a connection but no insight or true relationship. Moorehouse views people as a tool to advance his own business and political agendas demonstrating that connections with people are often made out of selfish, egotistical motives.

Magazine profile

From a September 2006 The Atlantic article , by Marshall Poe, describing Jimmy Wales, Wikipedia, and collaborative knowledge. Notice how the first sentence introduces a philosophical issue that the body sentences define and link to both Wikipedia and Wales’s own personality.

Wales was an advocate of what is generically termed “openness” online. An “open” online community is one with few restrictions on membership or posting-everyone is welcome, and anyone can say anything as long as it’s generally on point and doesn’t include gratuitous ad hominem attacks. Openness fit not only Wales’s idea of objectivism, with its emphasis on reason and rejection of force, but also his mild personality. He doesn’t like to fight. He would rather suffer fools in silence, waiting for them to talk themselves out, than confront them. This patience would serve Wales well in the years to come.

From Spontaneous Gestures Influence Strategy Choices in Problem Solving (2011). UW-Madison Psychology Professor Martha Alibali et al. present empirical research on how children use physical gestures to acquire mathematical problem-solving knowledge. Notice the clarity of expression in the first paragraph’s topic sentence: the writer provides sufficient set-up to prepare readers for the data which comes at the end of each paragraph.

We predicted that participants in the gesture-allowed condition would be less likely than participants in the gesture-prohibited condition to generate the parity strategy, because the availability of gesture would promote use of perceptual-motor strategies instead. This was indeed the case; the proportion of participants who used the parity strategy on at least one trial was .74 in the gesture-allowed condition and .91 in the gesture-prohibited condition, _2(1, N = 85) = 4.17, p = .04 (Fig. 1). Once they generated the parity strategy, most participants (89%) used it on all subsequent trials.

Mechanical engineering

From Mounting methodologies to measure EUV reticle nonflatness (SPIE Proceedings 7470, 2009), by the lab of UW–Madison Professor Roxanne L. Engelstad. Notice how Battula et al. signal the practical consequence of their findings and also suggest that another result would be possible depending on further research.

Unfortunately, to map the entire reticle with a single measurement, a 12 in. beam expander is needed. With such a large optical system, the expander must be held rigidly, not allowing it to tip or tilt. Since the UW-CMC mount must remain vertical to be effective, it cannot be used in this scenario. Consequently, the application of this mount is limited. Thus, a number of new designs have been proposed by industry to address the alignment issues and provide for other options, such as automated handling. Three of these designs are described and evaluated in the following sections.

Literary studies

From Dorothy West’s Paradise: A Biography of Class and Color (2012), by UW–Madison Professor Sherrard-Johnson. Notice how the first two sentences give crucial background information in order to set up the topic sentence.

In Contested Waters: A Social History of Swimming Pools in America, Jeff Wiltse examines how U.S. swimming pools were transformed from interracial single-sex spaces in which class and gender were more important than race to “leisure resorts, where practically everyone in the community except black Americans swam together.” His study then follows what he calls the second social transformation—”when black Americans gained access through legal and social protest” and “white swimmers generally abandoned them for private pools.” The various iterations of West’s story, which discuss the span from 1950 to 1980, fall between these two moments in social and legal history. I am particularly intrigued by how the national history of segregated bathing areas informs the local, particular event described by West. Does the exclusion of blacks from the high beach parallel the segregation of public pools? In the early twentieth century, public bathing spaces were notoriously violent. The Chicago Riot in 1919 was touched off when white bathers threw rocks at black teenagers who had drifted into a white beach on Lake Michigan. Northerners’ use of pools during the Progressive era reinforced class and gender but not racial distinction. Working-class folk did not swim with the upper classes, but they were not as concerned about color. Following the Great Migration, the concerns about intimacy and sexuality that have always been latent in conversations about public space (in particular the public space of the pool) were directed at blacks. The peculiar democracy of the beach—in bathing suits it is more difficulty to determine class‐worked against black Americans. Wiltse marks this shift between the years of 1920 and 1940. The social changes that took place during this period shape West’s complex politics. (26)

Legal writing

Former UW–Madison School of Law Professor Arthur F. McEvoy wrote this model paragraph as part of a memorandum on effective writing. Notice that each of the body sentences illustrates and develops the main idea or topic sentence.

The ideal paragraph contains five sentences. The topic sentence almost always comes first and states as clearly as possible the point that the paragraph makes, just as the first sentence of this paragraph did. The three middle sentences of the paragraph follow the topic sentence in some rational order and substantiate it with examples, analysis, or other kind of development; if written clearly, middle sentences may employ conjunctions or subordinate clauses to put across complex ideas without breaking the basic form. Every well-written paragraph ends with a “clincher” sentence that in some way signals completion of the paragraph’s point and places it in context, either by restating the topic sentence, relating the topic back to the thesis of the writing as a whole, or by providing a transition to the paragraph that follows. While good style may require a writer to vary this basic form occasionally, the five-sentence model captures the Platonic essence of the paragraph and most effectively accomplishes its purpose, which is to state a single idea, in sequence, discretely and comprehensively.

What is a paragraph?

A paragraph is a series of related sentences developing a central idea, called the topic . Try to think about paragraphs in terms of thematic unity: a paragraph is a sentence or a group of sentences that supports one central, unified idea. Paragraphs add one idea at a time to your broader argument.

How do I unify my ideas in a paragraph?

Probably the most effective way to achieve paragraph unity is to express the central idea of the paragraph in a topic sentence .

Topic sentences are similar to mini thesis statements . Like a thesis statement, a topic sentence has a specific main point. Whereas the thesis is the main point of the essay, the topic sentence is the main point of the paragraph. Like the thesis statement, a topic sentence has a unifying function. But a thesis statement or topic sentence alone doesn’t guarantee unity. An essay is unified if all the paragraphs relate to the thesis, whereas a paragraph is unified if all the sentences relate to the topic sentence. Note: Not all paragraphs need topic sentences. In particular, opening and closing paragraphs, which serve different functions from body paragraphs, generally don’t have topic sentences.

In academic writing, the topic sentence nearly always works best at the beginning of a paragraph so that the reader knows what to expect:

The embrace of Twitter by politicians and journalists has been one of its most notable features in recent years: for both groups the use of Twitter is becoming close to a requirement. —Paul Bernal, “A Defence of Responsible Tweeting”

This topic sentence forecasts the central idea or main point of the paragraph: “politicians” and “journalists” rely on Twitter. The rest of the paragraph will focus on these two Twitter-user groups, thereby fulfilling the promise made by the topic sentence. By avoiding irrelevant information that does not relate to the topic sentence, you can compose a unified paragraph.

How do I develop my ideas in a paragraph?

Often, the body paragraph demonstrates and develops your topic sentence through an ordered, logical progression of ideas. There are a number of useful techniques for expanding on topic sentences and developing your ideas in a paragraph. Illustration in a paragraph supports a general statement by means of examples, details, or relevant quotations (with your comments).

In Harry’s world fate works not only through powers and objects such as prophecies, the Sorting Hat, wands, and the Goblet of Fire, but also through people. Repeatedly, other characters decide Harry’s future for him, depriving him of freedom and choice. For example, before his eleventh birthday, the Dursleys control Harry’s life, keeping from him knowledge of his past and understanding of his identity (Sorcerer’s 49). In Harry Potter and the Chamber of Secrets , Dobby repeatedly assumes control over events by intercepting Ron’s and Hermione’s letters during the summer; by sealing the barrier to Platform 93⁄4, causing Harry to miss the Hogwarts Express; and by sending a Bludger after Harry in a Quidditch match, breaking his wrist. Yet again, in Harry Potter and the Prisoner of Azkaban , many adults intercede while attempting to protect Harry from perceived danger, as Snape observes: “Everyone from the Minister of Magic downward has been trying to keep famous Harry Potter safe from Sirius Black” (284). All these characters, as enactors of fate, unknowingly drive Harry toward his destiny by attempting to control or to direct his life, while themselves controlled and directed by fate. —Julia Pond, “A Story of the Exceptional: Fate and Free Will in the Harry Potter Series”

The definition paragraph does exactly what you would expect: it defines a term, often by drawing distinctions between the term and other related ones. The definition that you provide will often be specific to your subject area. Try to avoid perfunctory dictionary definitions that do not inform your analysis in a meaningful way.

Our typology is built on three dimensions: internality, types of participants, and the degree of effective resistance. For our study, a civil war is any armed conflict that involves (a) military action internal to the metropole, (b) the active participation of the national government, and (c) effective resistance by both sides. With these criteria, we differentiate civil wars from other types of internal violent conflicts. —Melvin Small and J. David Singer, Resort to Arms: International and Civil Wars, 1816–1980

The analysis or classification paragraph develops a topic by distinguishing its component parts and discussing each of these parts separately.

Policies of privatisation should be considered as responses to several distinct pressures. First, privatisation is a response by the state to internal forces such as increasing fiscal problems (O’Connor, 1973). It provides a means of lessening the state’s fiscal responsibilities by encouraging the development of private alternatives which, theoretically at least, do not draw upon the state’s financial reserves. Second, the promotion of private sector activity is a response to pressures originating ‘outside’ the state apparatus. These include demands from people who see a large state bureaucracy as inefficient and wasteful, demands from business interests who claim that they can overcome these inefficiencies, and pressures from client groups who seek to reduce their dependency on the welfare state by having more control over the services on which they depend. Clearly, this variety of calls for privatisation means that it is not a process with a uniform outcome; there exists a correspondingly wide variety of forms of privatisation. —Adapted from Glenda Laws, “Privatisation and the Local Welfare State”

A comparison or a contrast paragraph zeroes in on a key similarity or difference between, for instance, two sources, positions, or ideas. Decide whether to deal only with similarities or only with differences, or to cover both. Also, keep in mind that a single comparison can be spread out over two separate paragraphs. As the following topic sentence indicates, you should make your intention clear to readers from the outset.

Evidence from industrialized countries suggests that compared with older men, older women more often experience functional impairments and activity limitations, have longer durations of disability, and spend proportionately more remaining years of life disabled. —Kathryn M. Yount, “Differences in Disability among Older Women in Egypt and Tunisia”

A qualification paragraph acknowledges that what you previously asserted is not absolutely true or always applicable.

This study was a preliminary study of high school student value changes because of the terrorist attack on the U.S. The major limitations of this study were that the student population was from California and might not truly represent all high school students in the U.S. Further, this study could not be considered a truly longitudinal study because of privacy issues that prevented the researchers from identifying all the students who returned surveys before the attack. In addition, the senior class had graduated the previous year, and a much larger freshman class entered the school. These issues not only made the samples similar, but also different in their composition. The researchers will conduct periodic studies to explore whether these value changes are permanent and continue into adulthood. We do not know what if any changes will take place in their values as they grow older, and we will continue to explore their values in our longitudinal studies of the impact of the 9/11 terrorist attacks. —Edward F. Murphy, et al., “9/11 Impact on Teenage Values”

The process paragraph involves a straightforward step-by-step description. Process description often follows a chronological sequence.

In brief, the mummification process may be summarized as follows: extract, sterilize, dehydrate, perfume, seal, tag, and stock. All were done ceremoniously and with due respect to the dead body. The viscera were extracted through an incision about 10 inches long, usually made in the left side of the abdomen. Through this incision, all the “floating” contents of the abdominal cavity, namely, the stomach, the liver, the spleen, and the intestines, were removed but the kidneys were left in place. The diaphragm was then cut and the thoracic contents removed through the abdominal incision. The heart, which was considered the center of emotions and the seat of conscience, was left in place. The ancient Egyptians seem to have attached no importance to the brain, which was removed through the ethmoid bone. Following these extractions began the slow process of sterilization and dehydration of the body, accomplished by osmosis with dry natron. Resterilization of the cavities, perfuming, closing the incision, and wrapping the body with linen and with beeswax completed the process. Molten resin was used to seal the body and its wrappings, providing a barrier against insects and anaerobes. —Adapted from Mohamed E. Salem and Garabed Eknoyan, “The Kidney in Ancient Egyptian Medicine: Where Does it Stand?”

Very often, a single paragraph will develop by a combination of methods .

—Lynn E. McCutcheon, et al., “Conceptualization and Measurement of Celebrity Worship”

How do I make my ideas flow in a paragraph?

“Flow” is a word used to describe the way a paragraph moves from idea to idea. This movement occurs both within the paragraph and between paragraphs. The best overall strategy to enhance flow within a paragraph is to show connections . A variety of simple techniques can help you to clarify those connections and thereby communicate your intended logic. Deliberate repetition of key words helps. Reiterating the focus of your analysis by repeating key words or synonyms for key words enhances the overall flow of the paragraph. In the following example, the repetition of the key words “Canadian,” “nation,” and “communication” allows for clear flow throughout the paragraph.

It’s perhaps not surprising that Marshall McLuhan, the most influential communications expert of the twentieth century, was a Canadian . As a nation , we have been preoccupied with forging communication links among a sparse, widespread population. The old Canadian one-dollar bill, with its line of telephone poles receding to the distant horizon, illustrates this preoccupation. Year after year we strive to maintain a national radio and television broadcasting system in the face of foreign competition. We have been aggressive in entering the international high technology market with our telecommunications equipment. —Margot Northey, Impact: A Guide to Business Communication

While the deliberate repetition of a key word is a useful tool, you generally want to avoid repeating an entire idea. In particular, avoid ending a paragraph by making the same point you made in the topic sentence. This type of reiteration stalls or disrupts the development of ideas as well as the logical progression to the next paragraph. Strategic use of pronouns such as it , they , and this keeps the focus on the ideas announced at the beginning of the paragraph—as long as they are clearly linked to specific nouns. In the following example the antecedent is underlined and its corresponding pronoun is in bold.

Minois concluded his overview by suggesting that old age was something “which the early Middle Ages were decidedly not concerned about ” (1989: 155). This lack of concern was not because of the absence of old people, for Minois believed that “once they had survived to their 20th year, the men [sic] . . . could expect to live as long as we do” (1989: 149). Rather, he suggested, old people “played only a negligible social role and were dependent on the care of their families”—in effect they were marginalised by the society of the time (1989: 149). —Chris Gilleard, “Old Age in the Dark Ages”

Specialized linking words can also be powerful tools for pulling ideas together. But don’t just sprinkle them into your sentences—use them to support your logic.

To signal a change in ideas :

To signal a conclusion :

How long should a paragraph be?

Paragraphs vary in length depending on the needs of the paragraph. Usually, paragraphs are between one-third and two-thirds of a page double spaced.

A series of long paragraphs can make prose dense and unpleasant to read. Check any paragraph that is a page or longer to see whether it would work better as two or more paragraphs. Break it at a logical place (e.g., where your focus shifts), and see whether you need to create new topic sentences to make the shift clear.

Also look out for short paragraphs only two or three sentences long. They make academic writing seem disjointed or skimpy. Try combining short paragraphs with the preceding or following paragraph if they share the same topic. Short paragraphs might also need to be developed further. Make sure that nothing vital has been omitted.

11 Rules for Essay Paragraph Structure (with Examples)

How do you structure a paragraph in an essay?

If you’re like the majority of my students, you might be getting your basic essay paragraph structure wrong and getting lower grades than you could!

In this article, I outline the 11 key steps to writing a perfect paragraph. But, this isn’t your normal ‘how to write an essay’ article. Rather, I’ll try to give you some insight into exactly what teachers look out for when they’re grading essays and figuring out what grade to give them.

You can navigate each issue below, or scroll down to read them all:

1. Paragraphs must be at least four sentences long 2. But, at most seven sentences long 3. Your paragraph must be Left-Aligned 4. You need a topic sentence 5 . Next, you need an explanation sentence 6. You need to include an example 7. You need to include citations 8. All paragraphs need to be relevant to the marking criteria 9. Only include one key idea per paragraph 10. Keep sentences short 11. Keep quotes short

Paragraph structure is one of the most important elements of getting essay writing right .

As I cover in my Ultimate Guide to Writing an Essay Plan , paragraphs are the heart and soul of your essay.

However, I find most of my students have either:

• forgotten how to write paragraphs properly,
• gotten lazy, or
• never learned it in the first place!

Paragraphs in essay writing are different from paragraphs in other written genres .

In fact, the paragraphs that you are reading now would not help your grades in an essay.

That’s because I’m writing in journalistic style, where paragraph conventions are vastly different.

For those of you coming from journalism or creative writing, you might find you need to re-learn paragraph writing if you want to write well-structured essay paragraphs to get top grades.

Below are eleven reasons your paragraphs are losing marks, and what to do about it!

Essay Paragraph Structure Rules

1. your paragraphs must be at least 4 sentences long.

In journalism and blog writing, a one-sentence paragraph is great. It’s short, to-the-point, and helps guide your reader. For essay paragraph structure, one-sentence paragraphs suck.

A one-sentence essay paragraph sends an instant signal to your teacher that you don’t have much to say on an issue.

A short paragraph signifies that you know something – but not much about it. A one-sentence paragraph lacks detail, depth and insight.

Many students come to me and ask, “what does ‘add depth’ mean?” It’s one of the most common pieces of feedback you’ll see written on the margins of your essay.

Personally, I think ‘add depth’ is bad feedback because it’s a short and vague comment. But, here’s what it means: You’ve not explained your point enough!

If you’re writing one-, two- or three-sentence essay paragraphs, you’re costing yourself marks.

Always aim for at least four sentences per paragraph in your essays.

This doesn’t mean that you should add ‘fluff’ or ‘padding’ sentences.

Make sure you don’t:

a) repeat what you said in different words, or b) write something just because you need another sentence in there.

But, you need to do some research and find something insightful to add to that two-sentence paragraph if you want to ace your essay.

Check out Points 5 and 6 for some advice on what to add to that short paragraph to add ‘depth’ to your paragraph and start moving to the top of the class.

• How to Make an Essay Longer
• How to Make an Essay Shorter

2. Your Paragraphs must not be more than 7 Sentences Long

Okay, so I just told you to aim for at least four sentences per paragraph. So, what’s the longest your paragraph should be?

Seven sentences. That’s a maximum.

So, here’s the rule:

Between four and seven sentences is the sweet spot that you need to aim for in every single paragraph.

Here’s why your paragraphs shouldn’t be longer than seven sentences:

1. It shows you can organize your thoughts. You need to show your teacher that you’ve broken up your key ideas into manageable segments of text (see point 10)

2. It makes your work easier to read.   You need your writing to be easily readable to make it easy for your teacher to give you good grades. Make your essay easy to read and you’ll get higher marks every time.

One of the most important ways you can make your work easier to read is by writing paragraphs that are less than six sentences long.

3. It prevents teacher frustration. Teachers are just like you. When they see a big block of text their eyes glaze over. They get frustrated, lost, their mind wanders … and you lose marks.

To prevent teacher frustration, you need to ensure there’s plenty of white space in your essay. It’s about showing them that the piece is clearly structured into one key idea per ‘chunk’ of text.

Often, you might find that your writing contains tautologies and other turns of phrase that can be shortened for clarity.

3. Your Paragraph must be Left-Aligned

Turn off ‘Justified’ text and: Never. Turn. It. On. Again.

Justified text is where the words are stretched out to make the paragraph look like a square. It turns the writing into a block. Don’t do it. You will lose marks, I promise you! Win the psychological game with your teacher: left-align your text.

A good essay paragraph is never ‘justified’.

I’m going to repeat this, because it’s important: to prevent your essay from looking like a big block of muddy, hard-to-read text align your text to the left margin only.

You want white space on your page – and lots of it. White space helps your reader scan through your work. It also prevents it from looking like big blocks of text.

You want your reader reading vertically as much as possible: scanning, browsing, and quickly looking through for evidence you’ve engaged with the big ideas.

The justified text doesn’t help you do that. Justified text makes your writing look like a big, lumpy block of text that your reader doesn’t want to read.

What’s wrong with Center-Aligned Text?

While I’m at it, never, ever, center-align your text either. Center-aligned text is impossible to skim-read. Your teacher wants to be able to quickly scan down the left margin to get the headline information in your paragraph.

Not many people center-align text, but it’s worth repeating: never, ever center-align your essays.

Don’t annoy your reader. Left align your text.

4. Your paragraphs must have a Topic Sentence

The first sentence of an essay paragraph is called the topic sentence. This is one of the most important sentences in the correct essay paragraph structure style.

The topic sentence should convey exactly what key idea you’re going to cover in your paragraph.

Too often, students don’t let their reader know what the key idea of the paragraph is until several sentences in.

You must show what the paragraph is about in the first sentence.

You never, ever want to keep your reader in suspense. Essays are not like creative writing. Tell them straight away what the paragraph is about. In fact, if you can, do it in the first half of the first sentence .

I’ll remind you again: make it easy to grade your work. Your teacher is reading through your work trying to determine what grade to give you. They’re probably going to mark 20 assignments in one sitting. They have no interest in storytelling or creativity. They just want to know how much you know! State what the paragraph is about immediately and move on.

Suggested: Best Words to Start a Paragraph

Ideal Essay Paragraph Structure Example: Writing a Topic Sentence If your paragraph is about how climate change is endangering polar bears, say it immediately : “Climate change is endangering polar bears.” should be your first sentence in your paragraph. Take a look at first sentence of each of the four paragraphs above this one. You can see from the first sentence of each paragraph that the paragraphs discuss:

When editing your work, read each paragraph and try to distil what the one key idea is in your paragraph. Ensure that this key idea is mentioned in the first sentence .

(Note: if there’s more than one key idea in the paragraph, you may have a problem. See Point 9 below .)

The topic sentence is the most important sentence for getting your essay paragraph structure right. So, get your topic sentences right and you’re on the right track to a good essay paragraph.

5. You need an Explanation Sentence

All topic sentences need a follow-up explanation. The very first point on this page was that too often students write paragraphs that are too short. To add what is called ‘depth’ to a paragraph, you can come up with two types of follow-up sentences: explanations and examples.

Let’s take explanation sentences first.

Explanation sentences give additional detail. They often provide one of the following services:

Let’s go back to our example of a paragraph on Climate change endangering polar bears. If your topic sentence is “Climate change is endangering polar bears.”, then your follow-up explanation sentence is likely to explain how, why, where, or when. You could say:

Ideal Essay Paragraph Structure Example: Writing Explanation Sentences 1. How: “The warming atmosphere is melting the polar ice caps.” 2. Why: “The polar bears’ habitats are shrinking every single year.” 3. Where: “This is happening in the Antarctic ice caps near Greenland.” 4. When: “Scientists first noticed the ice caps were shrinking in 1978.”

You don’t have to provide all four of these options each time.

But, if you’re struggling to think of what to add to your paragraph to add depth, consider one of these four options for a good quality explanation sentence.

6. Your need to Include an Example

Examples matter! They add detail. They also help to show that you genuinely understand the issue. They show that you don’t just understand a concept in the abstract; you also understand how things work in real life.

Example sentences have the added benefit of personalising an issue. For example, after saying “Polar bears’ habitats are shrinking”, you could note specific habitats, facts and figures, or even a specific story about a bear who was impacted.

Ideal Essay Paragraph Structure Example: Writing an ‘Example’ Sentence “For example, 770,000 square miles of Arctic Sea Ice has melted in the past four decades, leading Polar Bear populations to dwindle ( National Geographic, 2018 )

In fact, one of the most effective politicians of our times – Barrack Obama – was an expert at this technique. He would often provide examples of people who got sick because they didn’t have healthcare to sell Obamacare.

What effect did this have? It showed the real-world impact of his ideas. It humanised him, and got him elected president – twice!

Be like Obama. Provide examples. Often.

7. All Paragraphs need Citations

Provide a reference to an academic source in every single body paragraph in the essay. The only two paragraphs where you don’t need a reference is the introduction and conclusion .

Let me repeat: Paragraphs need at least one reference to a quality scholarly source .

Let me go even further:

Students who get the best marks provide two references to two different academic sources in every paragraph.

Two references in a paragraph show you’ve read widely, cross-checked your sources, and given the paragraph real thought.

It’s really important that these references link to academic sources, not random websites, blogs or YouTube videos. Check out our Seven Best types of Sources to Cite in Essays post to get advice on what sources to cite. Number 6 w ill surprise you!

Ideal Essay Paragraph Structure Example: In-Text Referencing in Paragraphs Usually, in-text referencing takes the format: (Author, YEAR), but check your school’s referencing formatting requirements carefully. The ‘Author’ section is the author’s last name only. Not their initials. Not their first name. Just their last name . My name is Chris Drew. First name Chris, last name Drew. If you were going to reference an academic article I wrote in 2019, you would reference it like this: (Drew, 2019).

Where do you place those two references?

Place the first reference at the end of the first half of the paragraph. Place the second reference at the end of the second half of the paragraph.

This spreads the references out and makes it look like all the points throughout the paragraph are backed up by your sources. The goal is to make it look like you’ve reference regularly when your teacher scans through your work.

Remember, teachers can look out for signposts that indicate you’ve followed academic conventions and mentioned the right key ideas.

Spreading your referencing through the paragraph helps to make it look like you’ve followed the academic convention of referencing sources regularly.

Here are some examples of how to reference twice in a paragraph:

• If your paragraph was six sentences long, you would place your first reference at the end of the third sentence and your second reference at the end of the sixth sentence.
• If your paragraph was five sentences long, I would recommend placing one at the end of the second sentence and one at the end of the fifth sentence.

You’ve just read one of the key secrets to winning top marks.

8. Every Paragraph must be relevant to the Marking Criteria

Every paragraph must win you marks. When you’re editing your work, check through the piece to see if every paragraph is relevant to the marking criteria.

For the British: In the British university system (I’m including Australia and New Zealand here – I’ve taught at universities in all three countries), you’ll usually have a ‘marking criteria’. It’s usually a list of between two and six key learning outcomes your teacher needs to use to come up with your score. Sometimes it’s called a:

• Marking criteria
• Marking rubric
• (Key) learning outcome
• Indicative content

Check your assignment guidance to see if this is present. If so, use this list of learning outcomes to guide what you write. If your paragraphs are irrelevant to these key points, delete the paragraph .

Paragraphs that don’t link to the marking criteria are pointless. They won’t win you marks.

For the Americans: If you don’t have a marking criteria / rubric / outcomes list, you’ll need to stick closely to the essay question or topic. This goes out to those of you in the North American system. North America (including USA and Canada here) is often less structured and the professor might just give you a topic to base your essay on.

If all you’ve got is the essay question / topic, go through each paragraph and make sure each paragraph is relevant to the topic.

For example, if your essay question / topic is on “The Effects of Climate Change on Polar Bears”,

• Don’t talk about anything that doesn’t have some connection to climate change and polar bears;
• Don’t talk about the environmental impact of oil spills in the Gulf of Carpentaria;
• Don’t talk about black bear habitats in British Columbia.
• Do talk about the effects of climate change on polar bears (and relevant related topics) in every single paragraph .

You may think ‘stay relevant’ is obvious advice, but at least 20% of all essays I mark go off on tangents and waste words.

Stay on topic in Every. Single. Paragraph. If you want to learn more about how to stay on topic, check out our essay planning guide .

9. Only have one Key Idea per Paragraph

One key idea for each paragraph. One key idea for each paragraph. One key idea for each paragraph.

Don’t forget!

Too often, a student starts a paragraph talking about one thing and ends it talking about something totally different. Don’t be that student.

To ensure you’re focussing on one key idea in your paragraph, make sure you know what that key idea is. It should be mentioned in your topic sentence (see Point 3 ). Every other sentence in the paragraph adds depth to that one key idea.

If you’ve got sentences in your paragraph that are not relevant to the key idea in the paragraph, they don’t fit. They belong in another paragraph.

Go through all your paragraphs when editing your work and check to see if you’ve veered away from your paragraph’s key idea. If so, you might have two or even three key ideas in the one paragraph.

You’re going to have to get those additional key ideas, rip them out, and give them paragraphs of their own.

If you have more than one key idea in a paragraph you will lose marks. I promise you that.

The paragraphs will be too hard to read, your reader will get bogged down reading rather than scanning, and you’ll have lost grades.

10. Keep Sentences Short

If a sentence is too long it gets confusing. When the sentence is confusing, your reader will stop reading your work. They will stop reading the paragraph and move to the next one. They’ll have given up on your paragraph.

Short, snappy sentences are best.

Shorter sentences are easier to read and they make more sense. Too often, students think they have to use big, long, academic words to get the best marks. Wrong. Aim for clarity in every sentence in the paragraph. Your teacher will thank you for it.

The students who get the best marks write clear, short sentences.

When editing your draft, go through your essay and see if you can shorten your longest five sentences.

(To learn more about how to write the best quality sentences, see our page on Seven ways to Write Amazing Sentences .)

11. Keep Quotes Short

Eighty percent of university teachers hate quotes. That’s not an official figure. It’s my guestimate based on my many interactions in faculty lounges. Twenty percent don’t mind them, but chances are your teacher is one of the eight out of ten who hate quotes.

Teachers tend to be turned off by quotes because it makes it look like you don’t know how to say something on your own words.

Now that I’ve warned you, here’s how to use quotes properly:

Ideal Essay Paragraph Structure Example: How To Use Quotes in University-Level Essay Paragraphs 1. Your quote should be less than one sentence long. 2. Your quote should be less than one sentence long. 3. You should never start a sentence with a quote. 4. You should never end a paragraph with a quote. 5 . You should never use more than five quotes per essay. 6. Your quote should never be longer than one line in a paragraph.

The minute your teacher sees that your quote takes up a large chunk of your paragraph, you’ll have lost marks.

Your teacher will circle the quote, write a snarky comment in the margin, and not even bother to give you points for the key idea in the paragraph.

Avoid quotes, but if you really want to use them, follow those five rules above.

I’ve also provided additional pages outlining Seven tips on how to use Quotes if you want to delve deeper into how, when and where to use quotes in essays. Be warned: quoting in essays is harder than you thought.

Follow the advice above and you’ll be well on your way to getting top marks at university.

Writing essay paragraphs that are well structured takes time and practice. Don’t be too hard on yourself and keep on trying!

4 thoughts on “11 Rules for Essay Paragraph Structure (with Examples)”

Hello there. I noticed that throughout this article on Essay Writing, you keep on saying that the teacher won’t have time to go through the entire essay. Don’t you think this is a bit discouraging that with all the hard work and time put into your writing, to know that the teacher will not read through the entire paper?

Hi Clarence,

Thanks so much for your comment! I love to hear from readers on their thoughts.

Yes, I agree that it’s incredibly disheartening.

But, I also think students would appreciate hearing the truth.

Behind closed doors many / most university teachers are very open about the fact they ‘only have time to skim-read papers’. They regularly bring this up during heated faculty meetings about contract negotiations! I.e. in one university I worked at, we were allocated 45 minutes per 10,000 words – that’s just over 4 minutes per 1,000 word essay, and that’d include writing the feedback, too!

If students know the truth, they can better write their essays in a way that will get across the key points even from a ‘skim-read’.

I hope to write candidly on this website – i.e. some of this info will never be written on university blogs because universities want to hide these unfortunate truths from students.

Thanks so much for stopping by!

Regards, Chris

This is wonderful and helpful, all I say is thank you very much. Because I learned a lot from this site, own by chris thank you Sir.

Thank you. This helped a lot.

Definition and Examples of Paragraphing in Essays

Glossary of Grammatical and Rhetorical Terms

• An Introduction to Punctuation
• Ph.D., Rhetoric and English, University of Georgia
• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

Paragraphing is the practice of dividing a text into paragraphs . The purpose of paragraphing is to signal shifts in thinking and give readers a rest. 

Paragraphing is "a way of making visible to the reader the stages in the writer's thinking" (J. Ostrom, 1978). Although conventions about the length of paragraphs vary from one form of writing to another, most style guides recommend adapting paragraph length to your medium , subject, and audience . Ultimately, paragraphing should be determined by the rhetorical situation .

Examples and Observations

" Paragraphing is not such a difficult skill, but it is an important one. Dividing up your writing into paragraphs shows that you are organized, and makes an essay easier to read. When we read an essay we want to see how the argument is progressing from one point to the next. "Unlike this book, and unlike reports , essays don't use headings . This makes them look less reader-friendly, so it is important to use paragraphs regularly, to break up the mass of words and to signal the making of a new point. . . . An unparagraphed page gives the reader the feeling of hacking away through a thick jungle without a track in sight—not very enjoyable and very hard work. A neat series of paragraphs acts like stepping stones that can be followed pleasurably across the river." (Stephen McLaren, "Essay Writing Made Easy", 2nd ed. Pascal Press, 2001)

Paragraphing Basics

"The following principles should guide the way paragraphs are written for undergraduate assignments:​

• Every paragraph should contain a single developed idea...

Structuring Paragraphs

"Long paragraphs are daunting—rather like mountains—and they are easy to get lost in, for both readers and writers. When writers try to do too much in a single paragraph, they often lose the focus and lose contact with the larger purpose or point that got them into the paragraph in the first place. Remember that old high school rule about one idea to a paragraph? Well, it's not a bad rule, though it isn't exactly right because sometimes you need more space than a single paragraph can provide to lay out a complicated phase of your overall argument. In that case, just break wherever it seems reasonable to do so in order to keep your paragraphs from becoming ungainly. "When you draft , start a new paragraph whenever you feel yourself getting stuck—it's the promise of a fresh start. When you revise , use paragraphs as a way of cleaning up your thinking, dividing it into its most logical parts." (David Rosenwasser and Jill Stephen, "Writing Analytically," 5th ed. Thomson Wadsworth, 2009)

Paragraphing and the Rhetorical Situation

"The form, length, style, and positioning of paragraphs will vary, depending on the nature and conventions of the medium (print or digital), the interface (size and type of paper, screen resolution, and size), and the genre . For example, paragraphs in a newspaper are quite a bit shorter, typically, than paragraphs in a college essay because of the newspaper's narrow columns. On a website, paragraphs on the opening page may consist of more signposts than would be typical in a printed work, allowing readers to select which direction to track via hyperlink. Paragraphs in a work of creative nonfiction will likely include transitional words and sentence structures not often found in lab reports.

"In short, the rhetorical situation should always guide your use of paragraphing. When you understand paragraph conventions, your audience and purpose , your rhetorical situation, and your writing's subject matter, you will be in the best position to decide how to use paragraphs strategically and effectively to teach, delight, or persuade with your writing." (David Blakesley and Jeffrey Hoogeveen, "The Thomson Handbook." Thomson Learning, 2008)​

Editing by Ear for Paragraphs

"We think of paragraphing as an organizational skill and may teach it in conjunction with the prewriting or planning stages of writing. I have found, however, that young writers understand more about paragraphing and cohesive paragraphs when they learn about them in conjunction with editing . When developing writers know the reasons for paragraphing, they more readily apply them in the editing stage than in drafting.

"Just as students can be trained to hear end punctuation , they can also learn to hear where new paragraphs start and when sentences are off the topic ." (Marcia S. Freeman, "Building a Writing Community: A Practical Guide," rev. ed. Maupin House, 2003)

What is a Paragraph?

A paragraph is a series of sentences on a specific point or topic.  A well written paragraph must have a topic sentence which states the main idea: what the paragraph is about.  While some say the  topic sentence can be anywhere in the paragraph, it is best to put it as the first sentence in a paragraph.  The rest of the sentences in the paragraph support, elaborate, and/or further explain the main idea expressed in the topic sentence.

Paragraphs have varying length depending upon various factors.  An average paragraph in an academic essay is about six to eight sentences.

Types of Paragraphs

There are various types of paragraphs such as summaries, abstracts, and answers to questions for a specific assignment.  In addition, there are specialized types of paragraphs for various reports such as feasibility studies or performance reports.

The types of paragraphs covered in this lesson are general paragraphs as would be used in the body of a letter or an academic essay, including general research papers (research essays).

Developing Support

“enough” support.

Writers often want to know how many words a paragraph/unit of support should contain, and the answer is that it should develop the idea or point of the topic sentence completely enough to satisfy the writer and readers. Depending on their function, paragraphs/units of support can vary in length from one or two sentences, to over a page; however, in most college assignments, successfully developed paragraphs/units of support usually contain approximately one hundred to two hundred and fifty words and span one-fourth to two-thirds of a typed page. A series of short paragraphs in an academic essay can seem choppy and unfocused, whereas paragraphs that are one page or longer can tire readers. Giving readers a paragraph break on each page helps them maintain focus. This advice does not mean, of course, that composing a paragraph of a particular number of words or sentences guarantees an effective paragraph. Writers must provide enough supporting sentences within paragraphs to develop the topic sentence and simultaneously carry forward the essay’s main idea.

For example: In a descriptive paragraph about a room in the writer’s childhood home, a length of two or three sentences is unlikely to contain enough details to create a picture of the room in the reader’s mind, and it will not contribute in conveying the meaning of the place. In contrast, a half page paragraph, full of carefully selected vivid, specific details and comparisons, provides a fuller impression and engages the reader’s interest and imagination.

In descriptive or narrative paragraphs, supporting sentences present details and actions in vivid, specific language in objective or subjective ways, appealing to the readers’ senses to make them see and experience the subject. In addition, some sentences writers use make comparisons that bring together or substitute the familiar with the unfamiliar, thus enhancing and adding depth to the description of the incident, place, person, or idea.

In a persuasive essay about raising the wage for certified nursing assistants, a paragraph might focus on the expectations and duties of the job, comparing them to that of a registered nurse. Needless to say, a few sentences that simply list the certified nurse’s duties will not give readers a complete enough idea of what these healthcare professionals do. If readers do not have plenty of information about the duties and the writer’s experience in performing them for what she considers inadequate pay, the paragraph fails to do its part in convincing readers that the pay is inadequate and should be increased.

As a writer, you may want to develop units of support independently for each topic sentence, before you put the whole essay together. Or you may want to develop all of the support simultaneously as you draft the essay. Your approach may vary from essay to essay. As you write more essays, you’ll most likely discover the process of approach to developing support that works best for you.

Rethinking the 5-Paragraph Essay in the Age of AI

Will AI kill the five-paragraph essay? To find out, I asked my ninth grade English teacher.

The five-paragraph essay is a mainstay of high school writing instruction, designed to teach students how to compose a simple thesis and defend it in a methodical, easily graded package. It's literature analysis at its most basic, and most rigid, level.

A typical five-paragraph essay asks students to pick a simple thesis, usually from a list of prompts, and compose a short introductory paragraph, followed by three paragraphs each laying out a different piece of supporting evidence, followed by a final paragraph—usually beginning, "In conclusion…."

Critics   argue  this assignment kills student creativity and turns writing into an exercise in pure drudgery. I tend to agree, remembering my time spent composing five-paragraph essays as soul-rending—forcing me to focus on sticking to a formula and a restrictive prompt rather than actually analyzing the books I was reading.

But the sudden ubiquity of large language models such as ChatGPT threatens to upend this status quo.

"I am *shocked* by how good OpenAI's new chat" is, University of Toronto professor Kevin Bryan  tweeted  after the first release of ChatGPT. "You can no longer give take-home exams/homework."

To test this hypothesis, I sat down in front of ChatGPT and gave it a classic freshman-year English prompt: "Please write me an approximately 500-word, five-paragraph essay discussing the role of Newspeak in controlling the people of Oceania in George Orwell's novel,  1984 . Please use MLA formatting and include 1–2 quotes per paragraph."

In response, it spit out an—ahem— six-paragraph, 588-word essay .

" In George Orwell's dystopian novel '1984,' the ruling Party of Oceania employs Newspeak as a potent tool for controlling the thoughts and behaviors of its citizens, " the essay begins. " Newspeak, a language designed to limit freedom of expression and thought, serves as a mechanism for the Party to maintain its authoritarian rule and suppress dissent. Through the manipulation of language, the Party effectively restricts the ability of individuals to articulate dissenting ideas, ultimately consolidating its power over the population. "

And then I sent it to my ninth grade English teacher.

Corey Craft taught English at the Alabama School of Fine Arts for nine years and now serves as an instructor in the school's creative writing department. A decade ago, I first read  1984 for his class.

"I'd give this essay a mid-level B—an 85," he told me. "Is the content OK? Sure. It's a little surface-level…but it gets the major points right."

Yet he also noted the essay's impressive vocabulary—phrases such as " linguistic manipulation " and " reshape historical narratives "—would sound some alarm bells. "There are words and concepts used in this paper that I would find suspicious coming from the average ninth grader," Craft added.

ChatGPT also made another glaring fumble—producing a six-paragraph essay, despite my multiple attempts to rephrase the prompt so it would stick to just five paragraphs.

While the typical ninth grade cheater might not be clever enough to fix these mistakes—Craft says he sometimes sees plagiarism where students have copy-pasted text without changing the font or text color—it's only a matter of time before tools such as ChatGPT work out these kinks.

Much to the chagrin of the five-paragraph essay's harshest critics, myself included, it doesn't look like ChatGPT will spell the end of the assignment. While five-paragraph essays are achingly dull, they do serve a simple purpose—they match the median student's ability level, even if it means leaving behind the significant minority of kids who can barely read by eighth grade and infuriating a small cohort of  nerds  who end up getting degrees in Renaissance literature.

There simply isn't an obvious alternative to the five-paragraph essay—and certainly not one that is somehow immune from inevitable AI mimicry. In a ChatGPT-saturated world, teachers will likely resort to giving students handwritten, in-class five-paragraph essays instead of ditching the assignment entirely—even if this is "more of a pain for the student to complete and more of a pain for the teacher to grade," Craft notes.

In short, rather than reshape writing instruction, educators will find new, less technology-dependent ways to keep doing the same thing.

"That may take trial and error," Craft says, "but that's part of the fun of the job."

Writing Paragraphs

Introduction

Imagine reading one long block of text, with each idea blurring into the next. You are likely to lose interest in a piece of writing that is disorganized and spans many pages without breaks.

Paragraphs separate ideas into logical, manageable chunks, each paragraph focusing on only one main idea and presenting coherent sentences to support that one point. Because all the sentences in one paragraph support the same point, a paragraph may stand on its own. For most types of informative or persuasive academic writing, writers find it helpful to think of the paragraph analogous to an essay, as each is controlled by a main idea or point, and that idea is developed by an organized group of more specific ideas.

Thus, the thesis of the essay is analogous to the topic sentence of a paragraph, just as the supporting sentences in a paragraph are analogous to the supporting paragraphs in an essay.

In essays, each supporting paragraph adds another related main idea to support the writer's thesis, or controlling idea. Each related supporting idea is developed with facts, examples, and other details that explain it. By exploring and refining one idea at a time, writers build a strong case for their thesis.

Effective paragraphing makes the difference between a satisfying essay that readers can easily process and one that requires readers to mentally organize themselves. Thoughtful organization and development of each body paragraph leads to an effectively focused, developed, and coherent essay.

An effective paragraph contains three main parts:

• a topic sentence
• body, supporting sentences
• a concluding sentence

In informative and persuasive writing, the topic sentence is usually the first sentence or second sentence of a paragraph and expresses its main idea, followed by supporting sentences that help explain, prove, or enhance the topic sentence.

In narrative and descriptive paragraphs, however, topic sentences may be implied rather than explicitly stated, with all supporting sentences working to create the main idea. If the paragraph contains a concluding sentence, it is the last sentence in the paragraph and reminds the reader of the main point by restating it in different words. The following figure illustrates the most common paragraph structure for informative and persuasive college essays.

Paragraph Structure

Graphic Organizer

The number of supporting sentences varies according to the paragraph's purpose and the writer's sentence structure.

Creating Focused Paragraphs with Topic Sentences

The foundation of a paragraph is the topic sentence, which expresses the main idea or point of the paragraph.

The topic sentence functions two ways:

• it clearly refers to and supports the essay's thesis, and
• it indicates what will follow in the rest of the paragraph.

As the unifying sentence for the paragraph, it is the most general sentence, whereas all supporting sentences provide different types of more specific information, such as facts, details, or examples.

An effective topic sentence has the following characteristics:

A topic sentence provides an accurate indication of what will follow in the rest of the paragraph.

A good topic sentence is the most general sentence in the paragraph and thus does not include supporting details.

A good topic sentence is clear and easy to follow.

Location of Topic Sentences

A topic sentence can appear anywhere within a paragraph or can be implied (such as in narrative or descriptive writing).

In college-level expository or persuasive writing, placing an explicit topic sentence at the beginning of each paragraph (the first or second sentence) makes it easier for readers to follow the essay and for writers to stay on topic, but writers should be aware of variations and maintain the flexibility to adapt to different writing projects.

The following examples illustrate varying locations for the topic sentence. In each example, the topic sentence is underlined.

Topic Sentence Begins the Paragraph (General to Specific)

After reading the new TV guide this week, I wondered why we are still being bombarded with reality shows, a plague that continues to darken our airwaves. Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. "Prisoner" follows the daily lives of eight suburban housewives who have chosen to be put in jail for the purposes of this fake psychological experiment. A preview for the first episode shows the usual tears and tantrums associated with reality television. I dread to think what producers will come up with next season and hope that other viewers will express their criticism. These producers must stop the constant stream of meaningless shows without plotlines. We've had enough reality television to last us a lifetime!

The first sentence tells readers that the paragraph will be about reality television shows, and it expresses the writer's distaste for these shows through the use of the word "bombarded."

Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show and why the writer finds it unappealing. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show "Prisoner"). Most academic essays contain the topic sentence at the beginning of the first paragraph.

Topic Sentence Ends the Paragraph (Specific to General)

Last year, a cat traveled 130 miles to reach its family, who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals' senses are better than humans'). In this case, the supporting sentences are placed before the topic sentence and the concluding sentence is the same as the topic sentence.

This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

When the Topic Sentence Appears in the Middle of the Paragraph

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety--breathing exercises. It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It's amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the highlighted sentence is the topic sentence. It expresses the main idea: that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety.

Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic.

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all, a technique often used in descriptive and narrative writing. Instead of being directly stated, the main idea is implied in the content of the paragraph, as in the following narrative paragraph:

Heaving herself up the stairs, Luella had to pause for breath several times. She let out a wheeze as she sat down heavily in the wooden rocking chair. Tao approached her cautiously, as if she might crumble at the slightest touch. He studied her face, like parchment, stretched across the bones so finely he could almost see right through the skin to the decaying muscle underneath. Luella smiled a toothless grin.

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept--that Luella is extremely old. The topic sentence is thus implied rather than stated so that all the details in the paragraph can work together to convey the dominant impression of Luella's age. In a paragraph such as this one, an explicit topic sentence would seem awkward and heavy-handed. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.

Exercise: Choose the Most Effective Topic Sentence

In each of the following sentence pairs, choose the more effective topic sentence.

• This paper will discuss the likelihood of the Democrats winning the next election.
• To boost their chances of winning the next election, the Democrats need to listen to public opinion.
• The unrealistic demands of union workers are crippling the economy for three main reasons.
• Union workers are crippling the economy because companies are unable to remain competitive as a result of added financial pressure.
• Authors are losing money as a result of technological advances.
• The introduction of new technology will devastate the literary world.
• Rap music is produced by untalented individuals with oversized egos.
• This essay will consider whether talent is required in the rap music industry.

Exercise: Evaluating Topic Sentences

Read the following statements and evaluate each as a topic sentence. Say whether the sentence is Good, Not-Good, or Not a Sentence.

• Exercising three times a week is healthy.
• Sexism and racism exist in today's workplace.
• I think we should raise the legal driving age.
• Owning a business.
• There are too many dogs on the public beach.

Create a Topic Sentence

Create a topic sentence on each of the following subjects. Write your responses on your own sheet of paper.

• An endangered species
• The cost of fuel
• The legal drinking age
• A controversial film or novel.

Developing Paragraphs

Writers often want to know how many words a paragraph should contain, and the answer is that a paragraph should develop the idea, point, or impression completely enough to satisfy the writer and readers.

Depending on their function, paragraphs can vary in length from one or two sentences, to over a page; however, in most college assignments, successfully developed paragraphs usually contain approximately one hundred to two hundred and fifty words and span one-fourth to two-thirds of a typed page.

A series of short paragraphs in an academic essay can seem choppy and unfocused, whereas paragraphs that are one page or longer can tire readers. Giving readers a paragraph break on each page helps them maintain focus.

This advice does not mean, of course, that composing a paragraph of a particular number of words or sentences guarantees an effective paragraph. Writers must provide enough supporting sentences within paragraphs to develop the topic sentence and simultaneously carry forward the essay's main idea.

For example: In a descriptive paragraph about a room in the writer's childhood home, a length of two or three sentences is unlikely to contain enough details to create a picture of the room in the reader's mind, and it will not contribute in conveying the meaning of the place.

In contrast, a half page paragraph, full of carefully selected, vivid, specific details and comparisons provides a fuller impression and engages the reader's interest and imagination.

Descriptive Paragraphs

In descriptive or narrative paragraphs, supporting sentences present details and actions in vivid, specific language in objective or subjective ways, appealing to the readers' senses to make them see and experience the subject.

In addition, in some sentences, writers make comparisons that bring together or substitute the familiar with the unfamiliar, thus enhancing and adding depth to the description of the incident, place, person, or idea.

Persuasive Paragraphs

In a persuasive essay about raising the wage for certified nursing assistants, a paragraph might focus on the expectations and duties of the job, comparing them to that of a registered nurse.

Needless to say, a few sentences that simply list the certified nurse's duties will not give readers a complete enough idea of what these healthcare professionals do. If readers do not have plenty of information about the duties and the writer's experience in performing them for what she considers inadequate pay, the paragraph fails to do its part in convincing readers that the pay is inadequate and should be increased.

Informative or Persuasive Paragraphs

In informative or persuasive writing, a supporting sentence usually offers one of the following:

• Reason: The refusal of the baby boom generation to retire is contributing to the current lack of available jobs.
• Fact: Many families now rely on older relatives to support them financially.
• Statistic: Nearly 10 percent of adults are currently unemployed in the United States.
• Quotation: "We will not allow this situation to continue," stated Senator Johns.
• Example: Last year, Bill was asked to retire at the age of fifty-five.

The type of supporting sentence you choose will depend on what you are writing and why you are writing.

For example, if you are attempting to persuade your audience to take a particular position, you should rely on facts, statistics, and concrete examples, rather than personal opinions.

Personal testimony in the form of an extended example can be used in conjunction with the other types of support.

Consider the elements in the following paragraph:

Sometimes the writing situation does not allow for research to add specific facts or other supporting information, but paragraphs can be developed easily with examples from the writer's own experience.

Farheya, a student in a freshman English Composition class, quickly drafted an essay during a timed writing assignment in class. To practice improving paragraph development, she selected the body paragraph below to add support:

Topic: Would you be better off if you didn't own a television? Discuss.

Original Paragraph:

Lack of ownership of a television set is also a way to preserve innocence, and keep the exposure towards anything inappropriate at bay. From simply watching a movie, I have seen things I shouldn't have, no matter how fast I switch the channel. Television shows not only display physical indecency, but also verbal. Many times movies do voice-overs of profane words, but they also leave a few words uncensored. Since all ages can flip through and see or hear such things, television can be toxic for the mind, and without it I wouldn't have to worry about what I may accidentally see or hear.

The original paragraph identifies two categories of indecent material, and there is mention of profanity to provide a clue as to what the student thinks is indecent.

However, the paragraph could use some examples to make the idea of inappropriate material clearer. Farheya considered some of the television shows she had seen and made a few changes.

Revised paragraph:

Not owning a television set would also be a way to preserve innocence and keep my exposure to anything inappropriate at bay. While searching for a program to view, I have seen things I shouldn't have, no matter how fast I switched the channel. The synopsis of EuroTrip, which describes high school friends traveling across Europe, leads viewers to think that the film is an innocent adventure; however; it is filled with indecency, especially when the students reach Amsterdam. The movie Fast and Furious has the same problem since the women are all half-naked in half tops and mini-skirts or short-shorts. Television shows not only display physical indecency, but also verbal. Many television shows have no filters, and the characters say profane words freely. On Empire , one of the most viewed dramas today, the main characters Cookie and Lucious Lyon use profane words during their fights throughout entire episodes. Because The Big Bang Theory is a show about a group of science geeks and their cute neighbor, viewers might think that these science geniuses' conversations would be about their current research or other science topics. Instead, their characters regularly engage in conversations about their personal lives that should be kept private. The ease of flipping through channels and seeing or hearing such things makes television toxic for the mind, and without a television I wouldn't have to worry about what I may accidentally see or hear.

Farheya's addition of a few examples helps to convey why she thinks she would be better off without a television.

Consider the paragraph below on a literary topic, based on J. D. Salinger's short story "A Perfect Day for Bananafish" developed with specific examples from the text. Before Farheya could continue, she needed to first create a working thesis and determine the body paragraph topic:

Concluding Sentences

An effective concluding sentence draws together all the ideas raised in your paragraph. It reminds readers of the main point--the topic sentence--without restating it in exactly the same words. Using the sandwich example, the top bread (the topic sentence) and the bottom bread (the concluding sentence) are very similar. They frame the "meat" or body of the paragraph.

Compare the topic sentence and concluding sentence from the first example on hybrid cars:

Notice the use of the synonyms "advantages" and "benefits." The concluding sentence reiterates the idea that owning a hybrid is advantageous without using the exact same words. It also summarizes two examples of the advantages covered in the supporting sentences: low running costs and environmental benefits.

Writers should avoid introducing any new ideas into a concluding sentence because a conclusion is intended to provide the reader with a sense of completion. Introducing a subject that is not covered in the paragraph will confuse readers and weaken the writing.

A concluding sentence may do any of the following:

Example: Childhood obesity is a growing problem in the United States.

Example: A lack of healthy choices, poor parenting, and an addiction to video games are among the many factors contributing to childhood obesity.

Example: These statistics indicate that unless we take action, childhood obesity rates will continue to rise.

Example: Based on this research, more than 60 percent of children in the United States will be morbidly obese by the year 2030 unless we take evasive action.

Example: Childhood obesity is an entirely preventable tragedy.

Paragraph Length

Although paragraph length is discussed in the section on developing paragraphs with supporting sentences, some additional reminders about when to start a new paragraph may prove helpful to writers:

• If a paragraph is over a page long, consider providing a paragraph break for readers. Look for a logical place to divide the paragraph; then revise the opening sentence of the second paragraph to maintain coherence.
• A series of short paragraphs can be confusing and choppy. Examine the content of the paragraphs and combine ones with related ideas or develop each one further.
• When dialogue is used, begin a new paragraph each time the speaker changes. Begin a new paragraph to indicate a shift in subject, tone, or time and place.

Parts of a Paragraph

• Identify the topic sentence, supporting sentences, and concluding sentence in the following paragraph.
• Pair with another student and compare your answers.

The desert provides a harsh environment in which few mammals are able to adapt. Of these hardy creatures, the kangaroo rat is possibly the most fascinating. Able to live in some of the most arid parts of the southwest, the kangaroo rat neither sweats nor pants to keep cool. Its specialized kidneys enable it to survive on a miniscule amount of water. Unlike other desert creatures, the kangaroo rat does not store water in its body but instead is able to convert the dry seeds it eats into moisture. Its ability to adapt to such a hostile environment makes the kangaroo rat a truly amazing creature.

Improving Paragraph Coherence

A strong paragraph holds together well, flowing seamlessly from the topic sentence into the supporting sentences and on to the concluding sentence. To help organize a paragraph and ensure that ideas logically connect to one another, writers use a combination of elements:

• A clear organizational pattern: chronological (for narrative writing and describing processes), spatial (for descriptions of people or places), order of importance, general to specific (deductive), specific to general (inductive).
• Transitional words and phrases: These connecting words describe a relationship between ideas.
• Repetition of ideas: This element helps keep the parts of the paragraph together by maintaining focus on the main idea, so this element reinforces both paragraph coherence and unity.

In the following example, notice the use of transitions (in pink) and key words (in green):

Owning a hybrid car benefits both the owner and the environment. First, these cars get 20 percent to 35 percent more miles to the gallon than a fuel-efficient gas-powered vehicle. Second, they produce very few emissions during low speed city driving. Because they do not require gas, hybrid cars reduce dependency on fossil fuels, which helps lower prices at the pump. Alex bought a hybrid car two years ago and has been extremely impressed with its performance. "It's the cheapest car I've ever had," she said. "The running costs are far lower than previous gas-powered vehicles I've owned." Given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex's example in the near future.

Words such as "first" and "second" are transition words that show sequence or clarify order. They help organize the writer's ideas by showing that he or she has another point to make in support of the topic sentence. The transition word "because" is a transition word of consequence that continues a line of thought. It indicates that the writer will provide an explanation of a result. In this sentence, the writer explains why hybrid cars will reduce dependency on fossil fuels (because they do not require gas).

In addition to transition words, the writer repeats the word "hybrid" (and other references such as "these cars," and "they"), and ideas related to benefits to keep the paragraph focused on the topic and hold it together.

Summarizing Transitions

To include a summarizing transition for the concluding sentence, the writer could rewrite the final sentence as follows:

In conclusion, given the low running costs and environmental benefits of owning a hybrid car, it is likely that many more people will follow Alex's example in the near future.

Although the phrase "in conclusion" certainly reinforces the idea of summary and closure, it is not necessary in this case and seems redundant, as the sentence without the phrase already repeats and summarizes the benefits presented in the topic sentence and flows smoothly from the preceding quotation.

The second half of the sentence, in making a prediction about the future, signals a conclusion, also making the phrase "in conclusion" unnecessary.

The original version of the concluding sentence also illustrates how varying sentences openings can improve paragraph coherence. As writers continue to practice and develop their style, they more easily make these decisions between using standard transitional phrases and combining the repetition of key ideas with varied sentence openings.

The following table provides some useful transition words and phrases to connect sentences within paragraphs as well as to connect:

Table of Common Transitional Words and Phrases

Key takeaways.

• A paragraph contains three distinct components: a topic sentence, body, and concluding sentence.
• The topic sentence expresses the main idea of the paragraph.
• Good topic sentences are general enough to cover the supporting sentences and limited enough to be developed well.
• Topic sentences are clear and easy to follow, and provide an accurate indication of what will follow in the rest of the paragraph.
• Topic sentences may be explicit or implied. They are usually explicit in informative and persuasive essays, whereas they are often implied in narrative and descriptive writing.
• Topic sentences may be placed at the beginning, middle, or end of a paragraph. In most academic essays, the topic sentence is placed at the beginning of a paragraph.
• Supporting sentences help explain, prove, or enhance the topic sentence by offering facts, reasons, statistics, quotations, or examples.
• Concluding sentences summarize the key points in a paragraph and reiterate the main idea without repeating it word for word.
• Transitional words and phrases help organize ideas in a paragraph and show how these ideas relate to one another.
• Repetition of keywords helps keep paragraphs focused and coherent.

Jamie Raskin: How to Force Justices Alito and Thomas to Recuse Themselves in the Jan. 6 Cases

By Jamie Raskin

Mr. Raskin represents Maryland’s Eighth Congressional District in the House of Representatives. He taught constitutional law for more than 25 years and was the lead prosecutor in the second impeachment trial of Donald Trump.

Many people have gloomily accepted the conventional wisdom that because there is no binding Supreme Court ethics code, there is no way to force Associate Justices Samuel Alito and Clarence Thomas to recuse themselves from the Jan. 6 cases that are before the court.

Justices Alito and Thomas are probably making the same assumption.

But all of them are wrong.

It seems unfathomable that the two justices could get away with deciding for themselves whether they can be impartial in ruling on cases affecting Donald Trump’s liability for crimes he is accused of committing on Jan. 6. Justice Thomas’s wife, Ginni Thomas, was deeply involved in the Jan. 6 “stop the steal” movement. Above the Virginia home of Justice Alito and his wife, Martha-Ann Alito, flew an upside-down American flag — a strong political statement among the people who stormed the Capitol. Above the Alitos’ beach home in New Jersey flew another flag that has been adopted by groups opposed to President Biden.

Justices Alito and Thomas face a groundswell of appeals beseeching them not to participate in Trump v. United States , the case that will decide whether Mr. Trump enjoys absolute immunity from criminal prosecution, and Fischer v. United States , which will decide whether Jan. 6 insurrectionists — and Mr. Trump — can be charged under a statute that criminalizes “corruptly” obstructing an official proceeding. (Justice Alito said on Wednesday that he would not recuse himself from Jan. 6-related cases.)

Everyone assumes that nothing can be done about the recusal situation because the highest court in the land has the lowest ethical standards — no binding ethics code or process outside of personal reflection. Each justice decides for him- or herself whether he or she can be impartial.

Of course, Justices Alito and Thomas could choose to recuse themselves — wouldn’t that be nice? But begging them to do the right thing misses a far more effective course of action.

The U.S. Department of Justice — including the U.S. attorney for the District of Columbia, an appointed U.S. special counsel and the solicitor general, all of whom were involved in different ways in the criminal prosecutions underlying these cases and are opposing Mr. Trump’s constitutional and statutory claims — can petition the other seven justices to require Justices Alito and Thomas to recuse themselves not as a matter of grace but as a matter of law.

The Justice Department and Attorney General Merrick Garland can invoke two powerful textual authorities for this motion: the Constitution of the United States, specifically the due process clause, and the federal statute mandating judicial disqualification for questionable impartiality, 28 U.S.C. Section 455. The Constitution has come into play in several recent Supreme Court decisions striking down rulings by stubborn judges in lower courts whose political impartiality has been reasonably questioned but who threw caution to the wind to hear a case anyway. This statute requires potentially biased judges throughout the federal system to recuse themselves at the start of the process to avoid judicial unfairness and embarrassing controversies and reversals.

The constitutional and statutory standards apply to Supreme Court justices. The Constitution, and the federal laws under it, is the “ supreme law of the land ,” and the recusal statute explicitly treats Supreme Court justices as it does other judges: “Any justice, judge or magistrate judge of the United States shall disqualify himself in any proceeding in which his impartiality might reasonably be questioned.” The only justices in the federal judiciary are the ones on the Supreme Court.

This recusal statute, if triggered, is not a friendly suggestion. It is Congress’s command, binding on the justices, just as the due process clause is. The Supreme Court cannot disregard this law just because it directly affects one or two of its justices. Ignoring it would trespass on the constitutional separation of powers because the justices would essentially be saying that they have the power to override a congressional command.

When the arguments are properly before the court, Chief Justice John Roberts and Associate Justices Amy Coney Barrett, Neil Gorsuch, Ketanji Brown Jackson, Elena Kagan, Brett Kavanaugh and Sonia Sotomayor will have both a constitutional obligation and a statutory obligation to enforce recusal standards.

Indeed, there is even a compelling argument based on case law that Chief Justice Roberts and the other unaffected justices should raise the matter of recusal on their own, or sua sponte. Numerous circuit courts have agreed with the Eighth Circuit that this is the right course of action when members of an appellate court are aware of “ overt acts ” of a judge reflecting personal bias. Cases like this stand for the idea that appellate jurists who see something should say something instead of placing all the burden on parties in a case who would have to risk angering a judge by bringing up the awkward matter of potential bias and favoritism on the bench.

But even if no member of the court raises the issue of recusal, the urgent need to deal with it persists. Once it is raised, the court would almost surely have to find that the due process clause and Section 455 compel Justices Alito and Thomas to recuse themselves. To arrive at that substantive conclusion, the justices need only read their court’s own recusal decisions.

In one key 5-to-3 Supreme Court case from 2016, Williams v. Pennsylvania, Justice Anthony Kennedy explained why judicial bias is a defect of constitutional magnitude and offered specific objective standards for identifying it. Significantly, Justices Alito and Thomas dissented from the majority’s ruling.

The case concerned the bias of the chief justice of Pennsylvania, who had been involved as a prosecutor on the state’s side in an appellate death penalty case that was before him. Justice Kennedy found that the judge’s refusal to recuse himself when asked to do so violated due process. Justice Kennedy’s authoritative opinion on recusal illuminates three critical aspects of the current controversy.

First, Justice Kennedy found that the standard for recusal must be objective because it is impossible to rely on the affected judge’s introspection and subjective interpretations. The court’s objective standard requires recusal when the likelihood of bias on the part of the judge “is too high to be constitutionally tolerable,” citing an earlier case. “This objective risk of bias,” according to Justice Kennedy, “is reflected in the due process maxim that ‘no man can be a judge in his own case.’” A judge or justice can be convinced of his or her own impartiality but also completely missing what other people are seeing.

Second, the Williams majority endorsed the American Bar Association’s Model Code of Judicial Conduct as an appropriate articulation of the Madisonian standard that “no man can be a judge in his own cause.” Model Code Rule 2.11 on judicial disqualification says that a judge “shall disqualify himself or herself in any proceeding in which the judge’s impartiality might reasonably be questioned.” This includes, illustratively, cases in which the judge “has a personal bias or prejudice concerning a party,” a married judge knows that “the judge’s spouse” is “a person who has more than a de minimis interest that could be substantially affected by the proceeding” or the judge “has made a public statement, other than in a court proceeding, judicial decision or opinion, that commits or appears to commit the judge to reach a particular result.” These model code illustrations ring a lot of bells at this moment.

Third and most important, Justice Kennedy found for the court that the failure of an objectively biased judge to recuse him- or herself is not “harmless error” just because the biased judge’s vote is not apparently determinative in the vote of a panel of judges. A biased judge contaminates the proceeding not just by the casting and tabulation of his or her own vote but by participating in the body’s collective deliberations and affecting, even subtly, other judges’ perceptions of the case.

Justice Kennedy was emphatic on this point : “It does not matter whether the disqualified judge’s vote was necessary to the disposition of the case. The fact that the interested judge’s vote was not dispositive may mean only that the judge was successful in persuading most members of the court to accept his or her position — an outcome that does not lessen the unfairness to the affected party.”

Courts generally have found that any reasonable doubts about a judge’s partiality must be resolved in favor of recusal. A judge “shall disqualify himself in any proceeding in which his impartiality might reasonably be questioned.” While recognizing that the “challenged judge enjoys a margin of discretion,” the courts have repeatedly held that “doubts ordinarily ought to be resolved in favor of recusal.” After all, the reputation of the whole tribunal and public confidence in the judiciary are both on the line.

Judge David Tatel of the D.C. Circuit emphasized this fundamental principle in 2019 when his court issued a writ of mandamus to force recusal of a military judge who blithely ignored at least the appearance of a glaring conflict of interest. He stated : “Impartial adjudicators are the cornerstone of any system of justice worthy of the label. And because ‘deference to the judgments and rulings of courts depends upon public confidence in the integrity and independence of judges,’ jurists must avoid even the appearance of partiality.” He reminded us that to perform its high function in the best way, as Justice Felix Frankfurter stated, “justice must satisfy the appearance of justice.”

The Supreme Court has been especially disposed to favor recusal when partisan politics appear to be a prejudicial factor even when the judge’s impartiality has not been questioned. In Caperton v. A.T. Massey Coal Co. , from 2009, the court held that a state supreme court justice was constitutionally disqualified from a case in which the president of a corporation appearing before him had helped to get him elected by spending $3 million promoting his campaign. The court, through Justice Kennedy, asked whether, quoting a 1975 decision, “under a realistic appraisal of psychological tendencies and human weakness,” the judge’s obvious political alignment with a party in a case “poses such a risk of actual bias or prejudgment that the practice must be forbidden if the guarantee of due process is to be adequately implemented.”

The federal statute on disqualification, Section 455(b) , also makes recusal analysis directly applicable to bias imputed to a spouse’s interest in the case. Ms. Thomas and Mrs. Alito (who, according to Justice Alito, is the one who put up the inverted flag outside their home) meet this standard. A judge must recuse him- or herself when a spouse “is known by the judge to have an interest in a case that could be substantially affected by the outcome of the proceeding.”

At his Senate confirmation hearing, Chief Justice Roberts assured America that “judges are like umpires.”

But professional baseball would never allow an umpire to continue to officiate the World Series after learning that the pennant of one of the two teams competing was flying in the front yard of the umpire’s home. Nor would an umpire be allowed to call balls and strikes in a World Series game after the umpire’s wife tried to get the official score of a prior game in the series overthrown and canceled out to benefit the losing team. If judges are like umpires, then they should be treated like umpires, not team owners, fans or players.

Justice Barrett has said she wants to convince people “that this court is not comprised of a bunch of partisan hacks.” Justice Alito himself declared the importance of judicial objectivity in his opinion for the majority in the Dobbs v. Jackson Women’s Health Organization decision overruling Roe v. Wade — a bit of self-praise that now rings especially hollow.

But the Constitution and Congress’s recusal statute provide the objective framework of analysis and remedy for cases of judicial bias that are apparent to the world, even if they may be invisible to the judges involved. This is not really optional for the justices.

I look forward to seeing seven members of the court act to defend the reputation and integrity of the institution.

Jamie Raskin, a Democrat, represents Maryland’s Eighth Congressional District in the House of Representatives. He taught constitutional law for more than 25 years and was the lead prosecutor in the second impeachment trial of Donald Trump.
