thesis definition in essay writing

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

• Definition & Examples
• When & How to Write a Thesis

I. What is a Thesis?

The thesis (pronounced thee -seez), also known as a thesis statement, is the sentence that introduces the main argument or point of view of a composition (formal essay, nonfiction piece, or narrative). It is the main claim that the author is making about that topic and serves to summarize and introduce that writing that will be discussed throughout the entire piece. For this reason, the thesis is typically found within the first introduction paragraph.

II. Examples of Theses

Here are a few examples of theses which may be found in the introductions of a variety of essays :

In “The Mending Wall,” Robert Frost uses imagery, metaphor, and dialogue to argue against the use of fences between neighbors.

In this example, the thesis introduces the main subject (Frost’s poem “The Mending Wall”), aspects of the subject which will be examined (imagery, metaphor, and dialogue) and the writer’s argument (fences should not be used).

While Facebook connects some, overall, the social networking site is negative in that it isolates users, causes jealousy, and becomes an addiction.

This thesis introduces an argumentative essay which argues against the use of Facebook due to three of its negative effects.

During the college application process, I discovered my willingness to work hard to achieve my dreams and just what those dreams were.

In this more personal example, the thesis statement introduces a narrative essay which will focus on personal development in realizing one’s goals and how to achieve them.

III. The Importance of Using a Thesis

Theses are absolutely necessary components in essays because they introduce what an essay will be about. Without a thesis, the essay lacks clear organization and direction. Theses allow writers to organize their ideas by clearly stating them, and they allow readers to be aware from the beginning of a composition’s subject, argument, and course. Thesis statements must precisely express an argument within the introductory paragraph of the piece in order to guide the reader from the very beginning.

IV. Examples of Theses in Literature

For examples of theses in literature, consider these thesis statements from essays about topics in literature:

In William Shakespeare’s “ Sonnet 46,” both physicality and emotion together form powerful romantic love.

This thesis statement clearly states the work and its author as well as the main argument: physicality and emotion create romantic love.

In The Scarlet Letter, Nathaniel Hawthorne symbolically shows Hester Prynne’s developing identity through the use of the letter A: she moves from adulteress to able community member to angel.

In this example, the work and author are introduced as well as the main argument and supporting points: Prynne’s identity is shown through the letter A in three ways: adulteress, able community member, and angel.

John Keats’ poem “To Autumn” utilizes rhythm, rhyme, and imagery to examine autumn’s simultaneous birth and decay.

This thesis statement introduces the poem and its author along with an argument about the nature of autumn. This argument will be supported by an examination of rhythm, rhyme, and imagery.

V. Examples of Theses in Pop Culture

Sometimes, pop culture attempts to make arguments similar to those of research papers and essays. Here are a few examples of theses in pop culture:

America’s food industry is making a killing and it’s making us sick, but you have the power to turn the tables.

The documentary Food Inc. examines this thesis with evidence throughout the film including video evidence, interviews with experts, and scientific research.

Orca whales should not be kept in captivity, as it is psychologically traumatizing and has caused them to kill their own trainers.

Blackfish uses footage, interviews, and history to argue for the thesis that orca whales should not be held in captivity.

VI. Related Terms

Just as a thesis is introduced in the beginning of a composition, the hypothesis is considered a starting point as well. Whereas a thesis introduces the main point of an essay, the hypothesis introduces a proposed explanation which is being investigated through scientific or mathematical research. Thesis statements present arguments based on evidence which is presented throughout the paper, whereas hypotheses are being tested by scientists and mathematicians who may disprove or prove them through experimentation. Here is an example of a hypothesis versus a thesis:

Hypothesis:

Students skip school more often as summer vacation approaches.

This hypothesis could be tested by examining attendance records and interviewing students. It may or may not be true.

Students skip school due to sickness, boredom with classes, and the urge to rebel.

This thesis presents an argument which will be examined and supported in the paper with detailed evidence and research.

Introduction

A paper’s introduction is its first paragraph which is used to introduce the paper’s main aim and points used to support that aim throughout the paper. The thesis statement is the most important part of the introduction which states all of this information in one concise statement. Typically, introduction paragraphs require a thesis statement which ties together the entire introduction and introduces the rest of the paper.

VII. Conclusion

Theses are necessary components of well-organized and convincing essays, nonfiction pieces, narratives , and documentaries. They allow writers to organize and support arguments to be developed throughout a composition, and they allow readers to understand from the beginning what the aim of the composition is.

Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

How to write a thesis statement, what is a thesis statement.

Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow. We refer to that condensation as a thesis statement.

Why Should Your Essay Contain a Thesis Statement?

• to test your ideas by distilling them into a sentence or two
• to better organize and develop your argument
• to provide your reader with a “guide” to your argument

In general, your thesis statement will accomplish these goals if you think of the thesis as the answer to the question your paper explores.

How Can You Write a Good Thesis Statement?

Here are some helpful hints to get you started. You can either scroll down or select a link to a specific topic.

How to Generate a Thesis Statement if the Topic is Assigned How to Generate a Thesis Statement if the Topic is not Assigned How to Tell a Strong Thesis Statement from a Weak One

How to Generate a Thesis Statement if the Topic is Assigned

Almost all assignments, no matter how complicated, can be reduced to a single question. Your first step, then, is to distill the assignment into a specific question. For example, if your assignment is, “Write a report to the local school board explaining the potential benefits of using computers in a fourth-grade class,” turn the request into a question like, “What are the potential benefits of using computers in a fourth-grade class?” After you’ve chosen the question your essay will answer, compose one or two complete sentences answering that question.

Q: “What are the potential benefits of using computers in a fourth-grade class?” A: “The potential benefits of using computers in a fourth-grade class are . . .”

A: “Using computers in a fourth-grade class promises to improve . . .”

The answer to the question is the thesis statement for the essay.

[ Back to top ]

How to Generate a Thesis Statement if the Topic is not Assigned

Even if your assignment doesn’t ask a specific question, your thesis statement still needs to answer a question about the issue you’d like to explore. In this situation, your job is to figure out what question you’d like to write about.

A good thesis statement will usually include the following four attributes:

• take on a subject upon which reasonable people could disagree
• deal with a subject that can be adequately treated given the nature of the assignment
• express one main idea
• assert your conclusions about a subject

Let’s see how to generate a thesis statement for a social policy paper.

Brainstorm the topic . Let’s say that your class focuses upon the problems posed by changes in the dietary habits of Americans. You find that you are interested in the amount of sugar Americans consume.

You start out with a thesis statement like this:

Sugar consumption.

This fragment isn’t a thesis statement. Instead, it simply indicates a general subject. Furthermore, your reader doesn’t know what you want to say about sugar consumption.

Narrow the topic . Your readings about the topic, however, have led you to the conclusion that elementary school children are consuming far more sugar than is healthy.

You change your thesis to look like this:

Reducing sugar consumption by elementary school children.

This fragment not only announces your subject, but it focuses on one segment of the population: elementary school children. Furthermore, it raises a subject upon which reasonable people could disagree, because while most people might agree that children consume more sugar than they used to, not everyone would agree on what should be done or who should do it. You should note that this fragment is not a thesis statement because your reader doesn’t know your conclusions on the topic.

Take a position on the topic. After reflecting on the topic a little while longer, you decide that what you really want to say about this topic is that something should be done to reduce the amount of sugar these children consume.

You revise your thesis statement to look like this:

More attention should be paid to the food and beverage choices available to elementary school children.

This statement asserts your position, but the terms more attention and food and beverage choices are vague.

Use specific language . You decide to explain what you mean about food and beverage choices , so you write:

Experts estimate that half of elementary school children consume nine times the recommended daily allowance of sugar.

This statement is specific, but it isn’t a thesis. It merely reports a statistic instead of making an assertion.

Make an assertion based on clearly stated support. You finally revise your thesis statement one more time to look like this:

Because half of all American elementary school children consume nine times the recommended daily allowance of sugar, schools should be required to replace the beverages in soda machines with healthy alternatives.

Notice how the thesis answers the question, “What should be done to reduce sugar consumption by children, and who should do it?” When you started thinking about the paper, you may not have had a specific question in mind, but as you became more involved in the topic, your ideas became more specific. Your thesis changed to reflect your new insights.

How to Tell a Strong Thesis Statement from a Weak One

1. a strong thesis statement takes some sort of stand..

Remember that your thesis needs to show your conclusions about a subject. For example, if you are writing a paper for a class on fitness, you might be asked to choose a popular weight-loss product to evaluate. Here are two thesis statements:

There are some negative and positive aspects to the Banana Herb Tea Supplement.

This is a weak thesis statement. First, it fails to take a stand. Second, the phrase negative and positive aspects is vague.

Because Banana Herb Tea Supplement promotes rapid weight loss that results in the loss of muscle and lean body mass, it poses a potential danger to customers.

This is a strong thesis because it takes a stand, and because it's specific.

2. A strong thesis statement justifies discussion.

Your thesis should indicate the point of the discussion. If your assignment is to write a paper on kinship systems, using your own family as an example, you might come up with either of these two thesis statements:

My family is an extended family.

This is a weak thesis because it merely states an observation. Your reader won’t be able to tell the point of the statement, and will probably stop reading.

While most American families would view consanguineal marriage as a threat to the nuclear family structure, many Iranian families, like my own, believe that these marriages help reinforce kinship ties in an extended family.

This is a strong thesis because it shows how your experience contradicts a widely-accepted view. A good strategy for creating a strong thesis is to show that the topic is controversial. Readers will be interested in reading the rest of the essay to see how you support your point.

3. A strong thesis statement expresses one main idea.

Readers need to be able to see that your paper has one main point. If your thesis statement expresses more than one idea, then you might confuse your readers about the subject of your paper. For example:

Companies need to exploit the marketing potential of the Internet, and Web pages can provide both advertising and customer support.

This is a weak thesis statement because the reader can’t decide whether the paper is about marketing on the Internet or Web pages. To revise the thesis, the relationship between the two ideas needs to become more clear. One way to revise the thesis would be to write:

Because the Internet is filled with tremendous marketing potential, companies should exploit this potential by using Web pages that offer both advertising and customer support.

This is a strong thesis because it shows that the two ideas are related. Hint: a great many clear and engaging thesis statements contain words like because , since , so , although , unless , and however .

4. A strong thesis statement is specific.

A thesis statement should show exactly what your paper will be about, and will help you keep your paper to a manageable topic. For example, if you're writing a seven-to-ten page paper on hunger, you might say:

World hunger has many causes and effects.

This is a weak thesis statement for two major reasons. First, world hunger can’t be discussed thoroughly in seven to ten pages. Second, many causes and effects is vague. You should be able to identify specific causes and effects. A revised thesis might look like this:

Hunger persists in Glandelinia because jobs are scarce and farming in the infertile soil is rarely profitable.

This is a strong thesis statement because it narrows the subject to a more specific and manageable topic, and it also identifies the specific causes for the existence of hunger.

Thesis Definition

The thesis is one of the most important concepts in college expository writing. A thesis sentence focuses your ideas for the paper; it's your argument or insight or viewpoint crystallized into a single sentence that gives the reader your main idea. It's not only useful for the reading audience to understand the purpose of the essay; this purpose is also useful for you as a writer, as it indicates the type of support that will follow in the paper and may indicate a logical structure or order for that support. Thus, you need to have a good grasp of the concept of thesis in order to proceed.

The thesis identifies two basics:

• what your ideas are about, and
• what your ideas are (i.e. what you will be trying to prove).

There are two parts to a thesis sentence that reflect these basics.

• The topic in the thesis tells what you are writing about.
• The angle in the thesis tells what your ideas are about the topic (again, what you are trying to prove).

For example:

• All successful college students have certain basic characteristics. [The main topic is about college students, while the idea or angle about the topic is that successful students share certain characteristics. The thesis indicates the type of support needed--discussion of those characteristics that contribute to college success.]
• For most adult students returning to college, the problems that they face along the way are outweighed by their achievements. [The main topic is about adult college students, while the idea or angle about the topic is that problems are outweighed by achievements. The thesis indicates the type of support needed and the order of that support--an explanation of the problems first and then an explanation of achievements second.]
• Adult students returning to college make up a higher percentage of entering students than they did twenty years ago because of a number of statistical, economic, and social reasons. [The main topic is about adult students returning to college, while the idea or angle about the topic is that there are reasons for the higher percentage of adults returning to college. The thesis indicates the type of support needed and the order of that support--an explanation of the statistical reasons first, economic reasons second, and social reasons third.]

Do you understand the basic topic and angle concept? If so, then there are a few more things to consider about the thesis. (And if not, now's the time to start asking a learning coach for assistance, so Email [email protected] ). It's important to investigate additional thesis characteristics at this point to make sure that you'll be creating a working thesis sentence that is workable and appropriate for college essays.  In addition to knowing what a thesis is, you need to know what a thesis is not. A thesis sentence's angle should NOT be:

• Too broad. For example, the following thesis really doesn't pinpoint a specific insight about the topic:  Adult students returning to college have a hard time. In what ways do adult students have a hard time? You'd need to identify a more specific insight in this angle.
• Too narrow a statement of fact. For example, the following thesis really cannot be developed into a full essay because the angle doesn't contain the writer's own thoughts or insights about the subject:  Adult students returning to college read an average of 7.5 books per term. A reader may respond by saying, "So what?" A narrow statement of fact does not contain your own personal analysis, argument, or interpretation of the topic--that all-important angle which a thesis must have.
• An announcement. For example, the following really is not a thesis at all because it lacks an angle that gives the writer's own insight into the topic: My topic is the adult student returning to college. Again, "So what?" What's the reader's idea here?

Once you create a working thesis, you should assess it to make sure that it fulfills thesis characteristics.  Make sure it has a clear topic (indication of what the thesis is about) and angle (what your own ideas are about the topic, i.e. what you are trying to prove). Make sure that the angle is not too broad, too narrow, a statement of fact, or an announcement. Work with the angle to make it indicate the order of your support, if you choose to do that for yourself or for your reading audience. And realize that the thesis is a working thesis until you finalize the essay (it's okay to revise the thesis as you go along, just as long as you retain important thesis characteristics.)

Writing a Thesis Statement — Definition, Types, and Examples

What is a thesis statement?

A thesis statement is a single sentence that identifies the topic and purpose of a scholarly research paper or academic writing. A thesis statement directly or indirectly presents the main points of the paper. Information presented in the essay should tie directly back to the thesis.

Overall, a good thesis statement accomplishes the following:

Identifies the purpose of the essay

Expresses the writer's position/opinion

Lists the main supports (optional)

Briefly summarizes the writer's conclusion(s)

Establish if the essay is explanatory, argumentative, or analytical

People often confuse thesis statements with topic sentences , which start each body paragraph. Typically, the thesis statement is the final sentence in the introductory paragraph and acts as a “road map” for the rest of the paper.

Types of thesis statements

The three main types of thesis statements are explanatory, argumentative, and analytical.

Explanatory thesis statements are used in expository essays that focus solely on informing the reader. Papers with this type of thesis do not contain the writer's opinion, nor do they try to persuade the reader.

The three main branches of science taught in public schools include biology, chemistry, and physics.

Argumentative thesis statements identify the writer's position or point of view on a given topic. Argumentative essays persuade the reader to agree with the writer's stance. If the reader cannot agree or disagree with the claim in the thesis, then it is not argumentative.

Public schools should place more emphasis on the arts because they encourage creativity, help improve academic development, and provide a beneficial emotional outlet.

Analytical thesis statements are used in papers that analyze how or why something does what it does. These thesis statements identify what the writer is analyzing, the parts of the analysis, and the order of those parts.

An analysis of course requirements in public schools suggests access to more electives can increase graduation rates.

How to write a thesis statement

When writing a thesis, the following guidelines apply:

Step 1: Determine the type of paper (explanatory, argumentative, or analytical).

Step 2: Identify the topic, position/claim, and supports of the essay.

Step 3: Determine if the supports should be included within the thesis. Although they are considered optional, they might be required depending on the audience and purpose of the essay.

Step 4: Compose a sentence that includes the topic, position, and supports (optional). While a thesis statement can be more than one sentence, it should not exceed two.

Step 5: Place the thesis statement at the end of the introductory paragraph(s). Placing it at the end of the introduction and before the supports allows the reader to focus on the paper’s main purpose.

Thesis statement examples

The following examples highlight each type of thesis statement.

Topic: Alternative Energy Sources

Explanatory Thesis: Alternative energy sources that can supplement the use of fossil fuels include solar, wind, and geothermal.

Argumentative Thesis: To combat reliance on foreign sources of fossil fuels, the United States would benefit from focusing on alternative energy options.

Analytical Thesis: Analysis suggests that replacing fossil fuels with alternative energy sources could negatively impact the economy.

Topic: Social Media

Explanatory Thesis: Three of the first platforms that influenced the world of social media include Facebook, Twitter, and Instagram.

Argumentative Thesis: Social media negatively influences society as it increases opportunities for cyberbullying, limits face-to-face interactions, and creates unrealistic expectations.

Analytical Thesis: An analysis of the use of social media suggests itis irrevocably harming the development of teenagers.

Topic: Standardized Testing

Explanatory Thesis: Standardized tests such as the ACT and SAT play a limited role in influencing college acceptance.

Argumentative Thesis: Standardized testing should not be required because it increases anxiety, does not measure progress, and cannot predict future success.

Analytical Thesis: Analysis suggests that standardized testing in elementary and high school negatively impacts students' academic success.

Thesis and Purpose Statements

Use the guidelines below to learn the differences between thesis and purpose statements.

In the first stages of writing, thesis or purpose statements are usually rough or ill-formed and are useful primarily as planning tools.

A thesis statement or purpose statement will emerge as you think and write about a topic. The statement can be restricted or clarified and eventually worked into an introduction.

As you revise your paper, try to phrase your thesis or purpose statement in a precise way so that it matches the content and organization of your paper.

Thesis statements

A thesis statement is a sentence that makes an assertion about a topic and predicts how the topic will be developed. It does not simply announce a topic: it says something about the topic.

Good: X has made a significant impact on the teenage population due to its . . . Bad: In this paper, I will discuss X.

A thesis statement makes a promise to the reader about the scope, purpose, and direction of the paper. It summarizes the conclusions that the writer has reached about the topic.

A thesis statement is generally located near the end of the introduction. Sometimes in a long paper, the thesis will be expressed in several sentences or an entire paragraph.

A thesis statement is focused and specific enough to be proven within the boundaries of the paper. Key words (nouns and verbs) should be specific, accurate, and indicative of the range of research, thrust of the argument or analysis, and the organization of supporting information.

Purpose statements

A purpose statement announces the purpose, scope, and direction of the paper. It tells the reader what to expect in a paper and what the specific focus will be.

Common beginnings include:

“This paper examines . . .,” “The aim of this paper is to . . .,” and “The purpose of this essay is to . . .”

A purpose statement makes a promise to the reader about the development of the argument but does not preview the particular conclusions that the writer has drawn.

A purpose statement usually appears toward the end of the introduction. The purpose statement may be expressed in several sentences or even an entire paragraph.

A purpose statement is specific enough to satisfy the requirements of the assignment. Purpose statements are common in research papers in some academic disciplines, while in other disciplines they are considered too blunt or direct. If you are unsure about using a purpose statement, ask your instructor.

This paper will examine the ecological destruction of the Sahel preceding the drought and the causes of this disintegration of the land. The focus will be on the economic, political, and social relationships which brought about the environmental problems in the Sahel.

Sample purpose and thesis statements

The following example combines a purpose statement and a thesis statement (bold).

The goal of this paper is to examine the effects of Chile’s agrarian reform on the lives of rural peasants. The nature of the topic dictates the use of both a chronological and a comparative analysis of peasant lives at various points during the reform period. . . The Chilean reform example provides evidence that land distribution is an essential component of both the improvement of peasant conditions and the development of a democratic society. More extensive and enduring reforms would likely have allowed Chile the opportunity to further expand these horizons.

What is a Thesis? Definition, Examples of Theses in Literature

Home » The Writer’s Dictionary » What is a Thesis? Definition, Examples of Theses in Literature

Thesis definition: A thesis is a statement in which the writer conveys his position regarding a topic.

What is a Thesis?

A thesis statement refers to part of an essay where the writer establishes his position regarding a topic. This is the position that the writer will further explore throughout his paper.

Example of Thesis

• Topic : religious freedom.
• Thesis : All citizens of the United States should be allowed to exercise the religion of their choice freely without interference from government.
• Explanation : In this thesis statement, the writer has taken the position that all citizens should be free to worship and practice their religion as they see fit. The government should not pressure citizens into any religion, and it should not persecute members of any faith community.

The Importance of a Thesis Statement

Thesis statements are important in order to establish the writer’s position regarding a topic or idea. They help to introduce the essay and set a focus for the reader.

Narrative thesis statements are found in narrative essays or in literature. They set the scene for the lesson that will be explored or taught through the piece.

Famous opening lines that exemplify a narrative thesis:

• The following narrative thesis is found in A Tale of Two Cities by Charles Dickens:

“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair.”

The Function of Thesis in Literature

Narrative thesis statements are important in literature in order to establish the purpose for the work or introduce the lesson that the novel will attempt to teach. This allows the reader to have a focus when beginning the novel in order to effectively engage them into the story.

Examples of Theses in Literature

In the memoir, I am Malala by Malala Yousafzai, a thesis statement can be found in the beginning pages of her story.

• “One year ago I left my home for school and never returned. I was shot by a Taliban bullet and was flown out of Pakistan unconscious. Some people say I will never return home, but I believe firmly in my heart that I will. To be torn from the country that you love is not something to wish on anyone.”

In this thesis statement, Yousafzai establishes the basis of her memoir, which is to tell the story of how she was forced to leave her home.

In Vladmir Nabokov’s Lolita , a thesis can be seen in the line, “Lolita, light of my life, the fire of my loins”.

Here the narrator establishes the identity of the young nymph that he is unhealthily obsessed with in the story. Lolita is a young child while he is a grown man; therefore, this statement creates the uneasy feeling about him that continues throughout the novel.

Summary: What Are Theses?

Define thesis in literature: In summation, a thesis statement establishes a purpose in the piece of writing. It may establish the lesson or story to be told, or in an essay it may establish the position the writer assumes when exploring a topic.

Either way, it is important for the thesis to be clear in order to effectively convey the writer’s message.

Final Example:

In Edgar Allan Poe’s “The Cask of Amontillado,” the thesis statement can be found in the first line of the short story. Montresor immediately states his purpose, “the thousand injuries of Fortunato I had borne as best I could, but when he ventured upon insult I vowed revenge.”

In this statement, Montresor states that he will be seeking revenge after being treated wrongly by Fortunato. By beginning the story with the narrative thesis establishes the purpose for the remainder of the piece.

A thesis ( THEE-ses ) is the main (or controlling) idea of an essay , report , speech , or research paper , sometimes written as a single declarative sentence known as a thesis statement . A thesis may be implied rather than stated directly. Plural: theses . It's also known as a thesis statement, thesis sentence, controlling idea.

In the classical rhetorical exercises known as the  progymnasmata , the  thesis is an exercise that requires a student to argue a case for one side or the other.

Etymology From the Greek, "to put"

Examples and Observations (Definition #1)

• "My thesis is simple: in the next century mankind must harness the nuclear genie if our energy needs are to be met and our security preserved." (John B. Ritch, "Nuclear Green," Prospect Magazine , March 1999)
• "We watch baseball: it's what we have always imagined life should be like. We play softball. It's sloppy--the way life really is." (from the introduction to Watching Baseball, Playing Softball)
• "Through Mansfield's skillful handling of point of view, characterization, and plot development, Miss Brill comes across as a convincing character who evokes our sympathy." (thesis statement in Miss Brill's Fragile Fantasy )
• "Suppose there were no critics to tell us how to react to a picture, a play, or a new composition of music. Suppose we wandered innocent as the dawn into an art exhibition of unsigned paintings. By what standards, by what values would we decide whether they were good or bad, talented or untalented, success or failures? How can we ever know that what we think is right?" (Marya Mannes, "How Do You Know It's Good?")
• "I think people are disturbed by the discovery that no longer is a small town autonomous--it is a creature of the state and of the Federal Government. We have accepted money for our schools, our libraries, our hospitals, our winter roads. Now we face the inevitable consequence: the benefactor wants to call the turns." (E.B. White, "Letter from the East")
• "It is possible to stop most drug addiction in the United States within a very short time. Simply make all drugs available and sell them at cost." (Gore Vidal, "Drugs")
• The Two Parts of an Effective Thesis "An effective thesis is generally composed of two parts: a topic and the writer's attitude or opinion about or reaction to that topic." (William J. Kelly, Strategy and Structure . Allyn and Bacon, 1996)
• Drafting and Revising a Thesis "It's a good idea to formulate a thesis early in the writing process , perhaps by jotting it on scratch paper, by putting it at the head of a rough outline , or by attempting to write an introductory paragraph that includes the thesis. Your tentative thesis will probably be less graceful than the thesis you include in the final version of your essay. Here, for example, is one student's early effort: Although they both play percussion instruments, drummers and percussionists are very different. The thesis that appeared in the final draft of the student's paper was more polished: Two types of musicians play percussion instruments--drummers and percussionists--and they are as different as Quiet Riot and the New York Philharmonic. Don't worry too soon about the exact wording of your thesis, however, because your main point may change as you refine your ideas." (Diana Hacker, The Bedford Handbook , 6th ed. Bedford/St. Martin's, 2002)
• A Good Thesis - "A good thesis tells the audience exactly what you want them to know, understand, and remember when your speech is done. Write it as a simple, declarative sentence (or two) that restates the speech purpose and states the main points that support the purpose. Although you may formulate a thesis statement early in the speech development process, you may revise and reword it as you research your topic.' (Sherwyn P. Morreale, Brian H. Spitzberg, and J. Kevin Barge, Human Communication: Motivation, Knowledge, and Skills , 2nd ed. Thomson Higher Education, 2007) - "An effective thesis statement singles out some aspect of a subject for attention and clearly defines your approach to it." (David Blakesley and Jeffrey L. Hoogeveen, Writing: A Manual for the Digital Age . Wadsworth, 2011)

Examples and Observations (Definition #2)

" Thesis . This advanced exercise [one of the progymnasmata] asks the student to write an answer to a 'general question' ( quaestio infina )--that is, a question not involving individuals. . . . Quintilian . . . notes that a general question can be made into a persuasive subject if names are added (II.4.25). That is, a Thesis would pose a general question such as 'Should a man marry?' or 'Should one fortify a city?' (A Special Question on the other hand would be 'Should Marcus marry Livia?' or 'Should Athens spend money to build a defensive wall?')" (James J. Murphy, A Short History of Writing Instruction: From Ancient Greece to Modern America , 2nd ed. Lawrence Erlbaum, 2001)

• How to Write a Definition Essay

A definition essay can be deceivingly difficult to write. This type of paper requires you to write a personal yet academic definition of one specific word. The definition must be thorough and lengthy. It is essential that you choose a word that will give you plenty to write about, and there are a few standard tactics you can use to elaborate on the term. Here are a few guidelines to keep in mind when writing a definition essay.

Part 1 of 3: Choosing the Right Word

1: choose an abstract word with a complex meaning. [1].

A simple word that refers to a concrete word will not give you much to write about, but a complex word that refers to an abstract concept provides more material to explore.

• Typically, nouns that refer to a person, place, or thing are too simple for a definition essay. Nouns that refer to an idea work better, however, as do most adjectives.
• For example, the word “house” is fairly simple and an essay written around it may be dull. By switching to something slightly more abstract like “home,” however, you can play around with the definition more. A “home” is a concept, and there are many elements involved in the creation of a “home.” In comparison, a “house” is merely a structure.

2: Make sure that the word is disputable.

Aside from being complex, the word should also refer to something that can mean different things to different people.

• A definition essay is somewhat subjective by nature since it requires you to analyze and define a word from your own perspective. If the answer you come up with after analyzing a word is the same answer anyone else would come up with, your essay may appear to lack depth.

3: Choose a word you have some familiarity with.

Dictionary definitions can only tell you so much. Since you need to elaborate on the word you choose to define, you will need to have your own base of knowledge or experience with the concept you choose.

• For instance, if you have never heard the term “pedantic,” your understanding of the word will be limited. You can introduce yourself to the word for your essay, but without previous understanding of the concept, you will not know if the definition you describe is truly fitting.

4: Read the dictionary definition.

While you will not be relying completely on the dictionary definition for your essay, familiarizing yourself with the official definition will allow you to compare your own understanding of the concept with the simplest, most academic explanation of it.

• As an example, one definition of “friend” is “a person attached to another by feelings of affection or personal regard.” [2] Your own ideas or beliefs about what a “friend” really is likely include much more information, but this basic definition can present you with a good starting point in forming your own.

5:  Research the word’s origins.

Look up your chosen word in the Oxford English Dictionary or in another etymology dictionary. [3]

• These sources can tell you the history behind a word, which can provide further insight on a general definition as well as information about how a word came to mean what it means today.

Part 2 of 3: Potential Elements of an Effective Definition

1: write an analysis. [4].

Separate a word into various parts. Analyze and define each part in its own paragraph.

• You can separate “return” into “re-” and “turn.” The word “friendship” can be separated into “friend” and “ship.”
• In order to analyze each portion of a word, you will still need to use additional defining tactics like negation and classification.
• Note that this tactic only works for words that contain multiple parts. The word “love,” for instance, cannot be broken down any further. If defining “platonic love,” though, you could define both “platonic” and “love” separately within your essay.

2:  Classify the term.

Specify what classes and parts of speech a word belongs to according to a standard dictionary definition.

• While this information is very basic and dry, it can provide helpful context about the way that a given word is used.

3: Compare an unfamiliar term to something familiar.

An unfamiliar or uncommon concept can be explained using concepts that are more accessible to the average person.

• Many people have never heard of the term “confrere,” for instance. One basic definition is “a fellow member of a profession, fraternity, etc.” As such, you could compare “confrere” with “colleague,” which is a similar yet more familiar concept. [5]

4:  Provide traditional details about the term.

Explain any physical characteristics or traditional thoughts used to describe your term of choice.

• The term “home” is often visualized physically as a house or apartment. In more abstract terms, “home” is traditionally thought to be a warm, cozy, and safe environment. You can include all of these features in a definition essay on “home.”

5: Use examples to illustrate the meaning.

People often relate to stories and vivid images, so using a fitting story or image that relates to the term can be used in clarifying an abstract, formless concept.

• In a definition essay about “kindness,” for example, you could write about an act of kindness you recently witnessed. Someone who mows the lawn of an elderly neighbor is a valid example, just as someone who gave you an encouraging word when you were feeling down might be.

6: Use negation to explain what the term does not mean.

If a term is often misused or misunderstood, mentioning what it is not is an effective way to bring the concept into focus.

• A common example would be the term “courage.” The term is often associated with a lack of fear, but many will argue that “courage” is more accurately described as acting in spite of fear.

7: Provide background information.

This is when your research about the etymology of a word will come in handy. Explain where the term originated and how it came to mean what it currently means.

Part 3 of 3: Definition Essay Structure

1: introduce the standard definition..

You need to clearly state what your word is along with its traditional or dictionary definition in your introductory paragraph.

• By opening with the dictionary definition of your term, you create context and a basic level of knowledge about the word. This will allow you to introduce and elaborate on your own definition.
• This is especially significant when the traditional definition of your term varies from your own definition in notable ways.

2: Define the term in your own words in your thesis.

Your actual thesis statement should define the term in your own words.

• Keep the definition in your thesis brief and basic. You will elaborate on it more in the body of your paper.
• Avoid using passive phrases involving the word “is” when defining your term. The phrases “is where” and “is when” are especially clunky. [6]
• Do not repeat part of the defined term in your definition.

3:  Separate different parts of the definition into separate paragraphs.

Each tactic or method used to define your term should be explored in a separate paragraph.

• Note that you do not need to use all the possible methods of defining a term in your essay. You should use a variety of different methods in order to create a full, well-rounded picture of the term, but some tactics will work great with some terms but not with others.

4: Conclude with a summary of your main points.

Briefly summarize your main points around the start of your concluding paragraph.

• This summary does not need to be elaborate. Usually, looking at the topic sentence of each body paragraph is a good way to form a simple list of your main points.
• You can also draw the essay to a close by referring to phrases or images evoked in your introduction.

5: Mention how the definition has affected you, if desired.

If the term you define plays a part in your own life and experiences, your final concluding remarks are a good place to briefly mention the role it plays.

• Relate your experience with the term to the definition you created for it in your thesis. Avoid sharing experiences that relate to the term but contradict everything you wrote in your essay.

Definition of thesis

Did you know.

In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.

Those who are high school or university students, or who were in those ranks before, probably know from first-hand experience what a synthesis essay is. It is one of the most popular tasks among teachers and professors as it shows the students’ abilities to carry out an evidence-based discussion. Nonetheless, the fact that it is widespread doesn’t make the synthesis essay format an easy one. As with any other type of writing, this one requires a knowledge of the proper structure and its components for the essay to be done properly. If you stick around till the end of this article, we promise that you’ll know all the essentials of a well-done synthesis paper. 

What is a Synthesis Essay

We acknowledge that you probably have a vision of what is a synthesis essay. Yet, we feel it is important to get the definition clearly and correctly. So, a synthesis essay is a type of writing that involves gathering information from various sources to develop a new idea or argument. Essentially, it combines points, data, and evidence from different places into a single, logical narrative. The central idea of a synthesis essay is represented by the thesis statement, which succinctly explains the main point of the essay. This new idea usually consolidates the main points and findings of the other sources.

One of the defining characteristics of a synthesis essay is its ability to integrate diverse viewpoints. This requires you not to just simply summarize the sources but also put them together to support your thesis. The goal is to create a blanket discussion that is supported by evidence from multiple perspectives. Synthesis essays can be: 

• explanatory, aiming to inform the reader, 
• or argumentative, focusing on persuading the reader of a particular viewpoint.

Usual Structure for a Well-Written Synthesis Essay

A well-written synthesis essay typically follows a structured format. It begins with an introduction that presents the main topic and includes a clear thesis statement. The body of the essay is divided into several paragraphs, each focusing on a specific point that supports the thesis. Each paragraph integrates information from different sources, with proper citations. Finally, the essay concludes by summarizing the main points and reiterating the thesis in a new way, offering some final thoughts or a call to action.

Forming a Synthesis Essay Thesis

Your thesis statement is the first step toward building a cohesive essay. It represents the central idea that ties together the various sources and perspectives you’ll discuss. To create a strong thesis, start with research. Thoroughly read your sources and understand the main points and arguments they present. Your thesis should concisely answer the question posed by your assignment, summarizing your stance and the reasoning behind it.

A good thesis statement for a synthesis essay should include the subject, your position on it, and the significance of your viewpoint. For instance, if your essay topic is about the allocation of tax dollars, your thesis might be: 

“Tax dollars should be invested in renewable energy projects because they create jobs, reduce environmental impact, and lead to long-term economic savings.” 

This statement clearly outlines the subject (tax dollars), your stance (investment in renewable energy), and the reasoning behind your position.

When writing your thesis, avoid being vague or overly broad. A thesis like “Renewable energy is good” is too general and lacks depth. Instead, focus on specific aspects and provide a clear rationale. Also, avoid a thesis that summarizes your sources without presenting an original idea or argument. Here are a couple more examples of well-written and formulated thesis statements for a synthesis essay:

“Denmark leads the world in renewable energy due to its comprehensive approach to energy conservation, including district heating, combined-heat-and-power stations, and a decentralized power grid system.”

“Implementing universal basic income can reduce poverty and stimulate economic growth by providing financial stability, encouraging entrepreneurship, and increasing consumer spending.”

How to Write a Synthesis Essay Step-by-Step

Okay, so as we got all the basics out of the way and have an idea of how to start a synthesis essay, we can finally move on to writing. It is much easier to divide the process into several parts, as this will help you follow the structure more closely, as well as build a more logical narrative. Here’s a step-by-step guide to help you through the process:

• Choose a Topic Begin by selecting a topic that interests you and is broad enough to have plenty of research material but specific enough to be manageable. Your topic should allow for the integration of various sources and perspectives.
• Conduct Research Gather information from reliable and relevant sources such as academic journals, books, and reputable websites. Make sure to annotate and take notes on key points, arguments, and evidence that support your thesis.
• Formulate a Thesis Statement Develop a clear and concise thesis statement reflecting the main point of your essay. Your thesis should bring together the ideas from your sources and present your stance on the topic. For instance, “Investing in renewable energy is necessary for economic growth and environmental sustainability.”

• Write the Introduction Start with a hook to grab your reader’s attention, provide some background information on your topic, and end with your thesis. The introduction sets the stage for your essay and prepares the reader for what’s to come.
• Draft the Body Paragraphs Each body paragraph should start with a topic sentence that introduces the main idea of the paragraph. Follow this with evidence from your sources, explaining how it supports your thesis. Don’t forget to analyze and connect the evidence to your argument, vividly presenting similarities and differences between sources. Address counterarguments to strengthen your position.
• Conclude Your Essay Summarize the main points discussed in the body paragraphs and restate your thesis in a new light. The conclusion should reinforce your argument and leave a lasting impression on the reader, emphasizing the significance of your synthesis.
• Proofread and Edit Review your essay for any grammatical errors, inconsistencies, or unclear points. Your writing should flow logically and your sources have to be correctly cited. A polished essay improves your credibility and makes your argument more persuasive.

After everything you’ve done, you can format the document according to the style requirements of your task. Remember, that the time you use in your narrative will depend on the formatting you use: for MLA you should write in the present tense, and for APA – in the past. Those of you who follow all of the mentioned steps will most likely end up with effectively synthesized information creating a well-structured and compelling essay.
