Cohesion And Coherence In Essay Writing

Table of contents, introduction.

Coherent essays are identified by relevance to the central topic. They communicate a meaningful message to a specific audience and maintain pertinence to the main focus. In a coherent essay, the sentences and ideas flow smoothly and, as a result, the reader can follow the ideas developed without any issues.

To achieve coherence in an essay, writers use lexical and grammatical cohesive devices. Examples of these cohesive devices are repetition, synonymy, antonymy, meronymy, substitutions , and anaphoric or cataphoric relations between sentences. We will discuss these devices in more detail below.

This article will discuss how to write a coherent essay. We will be focusing on the five major points.

We will start with definitions of coherence and cohesion.
Then, we will give examples of how a text can achieve cohesion.
We will see how a text can be cohesive but not coherent.
The structure of a coherent essay will also be discussed.
Finally, we will look in detail at ways to improve cohesion and write a coherent essay.

Before illustrating how to write coherent essays, let us start with the definitions of coherence and cohesion and list the ways we can achieve cohesion in a coherent text.

Definitions Cohesion and Coherence

In general, coherence and cohesion refer to how a text is structured so that the elements it is constituted of can stick together and contribute to a meaningful whole. In coherent essays, writers use grammatical and lexical cohesive techniques so that ideas can flow meaningfully and logically.

What is coherence?

Coherence refers to the quality of forming a unified consistent whole. We can describe a text as being coherent if it is semantically meaningful, that is if the ideas flow logically to produce an understandable entity.

If a text is coherent it is logically ordered and connected. It is clear, consistent, and understandable.

Coherence is related to the macro-level features of a text which enable it to have a sense as a whole.

What is cohesion?

Cohesion is commonly defined as the grammatical and lexical connections that tie a text together, contributing to its meaning (i.e. coherence.)

While coherence is related to the macro-level features of a text, cohesion is concerned with its micro-level – the words, the phrases, and the sentences and how they are connected to form a whole.

If the elements of a text are cohesive, they are united and work together or fit well together.

To summarize, coherence refers to how the ideas of the text flow logically and make a text semantically meaningful as a whole. Cohesion is what makes the elements (e.g. the words, phrases, clauses, and sentences) of a text stick together to form a whole.

How to Achieve Cohesion And Coherence In Essay Writing

There are two types of cohesion: lexical and grammatical. Writers connect sentences and ideas in their essays using both lexical and grammatical cohesive devices.

Lexical cohesion

We can achieve cohesion through lexical cohesion by using these techniques:

Repetition.

Now let’s look at these in more detail.

Repeating words may contribute to cohesion. Repetition creates cohesive ties within the text.

Birds are beautiful. I like birds.

You can use a word or phrase that means exactly or nearly the same as another word to achieve cohesion.

Paul saw a snake under the mattress. The serpent was probably hiding there for a long time.

Antonymy refers to the use of a word of opposite meaning. This is often used to create links between the elements of a text.

Old movies are boring, the new ones are much better.

This refers to the use of a word that denotes a subcategory of a more general class.

I saw a cat . The animal was very hungry and looked ill.

Relating a superordinate term (i.e. animal) to a corresponding subordinate term (i.e. cat) may create more cohesiveness between sentences and clauses.

Meronymy is another way to achieve cohesion. It refers to the use of a word that denotes part of something but which is used to refer to the whole of it for instance faces can be used to refer to people as in “I see many faces here”. In the following example, hands refer to workers.

More workers are needed. We need more hands to finish the work.

Grammatical cohesion

Grammatical cohesion refers to the grammatical relations between text elements. This includes the use of:

Cataphora .
Substitutions.
Conjunctions and transition words.

Let us illustrate the above devices with some examples.

Anaphora is when you use a word referring back to another word used earlier in a text or conversation.

Jane was brilliant. She got the best score.

The pronoun “she” refers back to the proper noun “Jane”.

Cataphora is the opposite of anaphora. Cataphora refers to the use of a word or phrase that refers to or stands for a following word or phrase.

Here he comes our hero. Please, welcome John .

The pronoun “he” refers back to the proper noun “John”.

Ellipsis refers to the omission from speech or writing of a word or words that are superfluous or able to be understood from contextual clues.

Liz had some chocolate bars, and Nancy an ice cream.

In the above example, “had” in “Nancy an ice cream” is left because it can be understood (or presupposed) as it was already mentioned previously in the sentence.

Elliptic elements can be also understood from the context as in:

A: Where are you going?

Substitutions

Substitutions refer to the use of a word to replace another word.

A: Which T-shirt would you like?
B: I would like the pink one .

Conjunctions transition words

Conjunctions and transition words are parts of speech that connect words, phrases, clauses, or sentences.

Examples of conjunctions: but, or, and, although, in spite of, because,
Examples of transition words: however, similarly, likewise, specifically, consequently, for this reason, in contrast to, accordingly, in essence, chiefly, finally.

Here are some examples:

I called Tracy and John.
He was tired but happy.
She likes neither chocolates nor cookies.
You can either finish the work or ask someone to do it for you.
He went to bed after he had done his homework.
Although she is very rich, she isn’t happy.
I was brought up to be responsible. Similarly , I will try to teach my kids how to take responsibility for their actions.

Cohesive but not coherent texts

Sometimes, a text may be cohesively connected, yet may still be incoherent.

Learners may wrongly think that simply linking sentences together will lead to a coherent text.

Here is an example of a text in which sentences are cohesively connected, yet the overall coherence is lacking:

The player threw the ball toward the goalkeeper. Balls are used in many sports. Most balls are spheres, but American football is an ellipsoid. Fortunately, the goalkeeper jumped to catch the ball. The crossbar in the soccer game is made of iron. The goalkeeper was standing there.

The sentences and phrases in the above text are decidedly cohesive but not coherent.

There is a use of:

Repetition of: the ball, goalkeeper, the crossbar.
Conjunctions and transition words: but, fortunately.

The use of the above cohesive devices does not result in a meaningful and unified whole. This is because the writer presents material that is unrelated to the topic. Why should a writer talk about what the crossbar is made of? And is talking about the form balls in sports relevant in this context? What is the central focus of the text?

A coherent essay has to be cohesively connected and logically expressive of the central topic.

How to write a coherent essay?

To achieve the coherence defined earlier, we need to follow these strategic steps:

1. Start with an outline

An outline is the general plan of your essays. It contains the ideas you will include in each paragraph and the sequence in which these ideas will be mentioned.

It is important to have an outline before starting to write. Spending a few minutes on the outline can be rewarding. An outline will organize your ideas and the end product can be much more coherent.

Here is how you can outline your writing so that you can produce a coherent essay:

Start with the thesis statement – the sentence that summarizes the topic of your writing.
Brainstorm the topic for a few minutes. Write down all the ideas related to the topic.
Sift the ideas brainstormed in the previous step to identify only the ideas worth including in your essay.
Organize ideas in a logical order so that your essay reflects the unified content that you want to communicate.
Each idea has to be treated in a separate paragraph.
Think of appropriate transitions between the different ideas.
Under each idea/paragraph, write down enough details to support your idea.

After identifying and organizing your ideas into different paragraphs, they have to fit within the conventional structure of essays.

2. Structure your essay

It is also important to structure your essay so that you the reader can identify the organization of the different parts of your essay and how each paragraph leads to the next one.

Here is a structure of an essay

3. Structure your paragraphs

Paragraphs have to be well-organized. The structure of each paragraph should have:

A topic sentence that is usually placed at the beginning,
Supporting details that give further explanation of the topic sentence,
And a concluding sentence that wraps up the content of the paragraph.

The supporting sentences in each paragraph must flow smoothly and logically to support the purpose of the topic sentence. Similarly, each paragraph has to serve the thesis statement, the main topic of the essay.

4. Relevance to the main topic

No matter how long the essay is, we should make sure that we stick to the topic we want to talk about. Coherence is about making everything flow smoothly to create unity. So, sentences and ideas must be relevant to the central thesis statement.

The writer has to maintain the flow of ideas to serve the main focus of the essay.

5. Stick to the purpose of the type of essay you’re-writing

Essays must be clear and serve a purpose and direction. This means that the writer’s thoughts must not go astray in developing the purpose of the essay.

Essays are of different types and have different purposes. Accordingly, students have to stick to the main purpose of each genre of writing.

An expository essay aims to inform, describe, or explain a topic, using essential facts to teach the reader about a topic.
A descriptive essay intends to transmit a detailed description of a person, event, experience, or object. The aim is to make the reader perceive what is being described.
A narrative essay attempts to tell a story that has a purpose. Writers use storytelling techniques to communicate an experience or an event.
In argumentative essays, writers present an objective analysis of the different arguments about a topic and provide an opinion or a conclusion of positive or negative implications. The aim is to persuade the reader of your point.

6. Use cohesive devices and signposting phrases

Sentences should be connected using appropriate cohesive devices as discussed above:

Cohesive devices such as conjunctions and transition words are essential in providing clarity to your essay. But we can add another layer of clarity to guide the reader throughout the essay by using signpost signals.

What is signposting in writing?

Signposting refers to the use of phrases or words that guide readers to understand the direction of your essay. An essay should take the reader on a journey throughout the argumentation or discussion. In that journey, the paragraphs are milestones. Using signpost signals assists the reader in identifying where you want to guide them. Signposts serve to predict what will happen, remind readers of where they are at important stages along the process, and show the direction of your essay.

Essay signposting phrases

The following are some phrases you can use to signpost your writing:

It should be noted though that using cohesive devices or signposting language may not automatically lead to a coherent text. Some texts can be highly cohesive but remain incoherent. Appropriate cohesion and signposting are essential to coherence but they are not enough. To be coherent, an essay has to follow, in addition to using appropriate cohesive devices, all the tips presented in this article.

7. Draft, revise, and edit

After preparing the ground for the essay, students produce their first draft. This is the first version of the essay. Other subsequent steps are required.

The next step is to revise the first draft to rearrange, add, or remove paragraphs, ideas, sentences, or words.

The questions that must be addressed are the following:

Is the essay clear? Is it meaningful? Does it serve the thesis statement (the main topic)?
Are there sufficient details to convey ideas?
Are there any off-topic ideas that you have to do without?
Have you included too much information? Does your writing stray off-topic?
Do the ideas flow in a logical order?
Have you used appropriate cohesive devices and transition words when needed?

Once the revision is done, it is high time for the editing stage. Editing involves proofreading and correcting mistakes in grammar and mechanics. Pay attention to:

Verb tense.
Subject-verb agreement.
Sentence structure. Have you included a subject a verb and an object (if the verb is transitive.)
Punctuation.
Capitalization.

Coherent essays are identified by relevance to the thesis statement. The ideas and sentences of coherent essays flow smoothly. One can follow the ideas discussed without any problems. Lexical and grammatical cohesive devices are used to achieve coherence. However, these devices are not sufficient. To maintain relevance to the main focus of the text, there is a need for a whole process of collecting ideas, outlining, reviewing, and editing to create a coherent whole.

Achieving coherence

“A piece of writing is coherent when it elicits the response: ‘I follow you. I see what you mean.’ It is incoherent when it elicits the response: ‘I see what you're saying here, but what has it got to do with the topic at hand or with what you just told me above?’ ” - Johns, A.M

Transitions

Parallelism, challenge task, what is coherence.

Coherence in a piece of writing means that the reader can easily understand it. Coherence is about making everything flow smoothly. The reader can see that everything is logically arranged and connected, and relevance to the central focus of the essay is maintained throughout.

Repetition in a piece of writing does not always demonstrate cohesion. Study these sentences:

So, how does repetition as a cohesive device work?

When a pronoun is used, sometimes what the pronoun refers to (ie, the referent) is not always clear. Clarity is achieved by repeating a key noun or synonym . Repetition is a cohesive device used deliberately to improve coherence in a text.

In the following text, decide ifthe referent for the pronoun it is clear. Otherwise, replace it with the key noun English where clarity is needed.

Suggested improvement

English has almost become an international language. Except for Chinese, more people speak it (clear reference; retain) than any other language. Spanish is the official language of more countries in the world, but more countries have English ( it is replaced with a key noun) as their official or unofficial second language. More than 70% of the world's mail is written in English ( it is replaced with a key noun). It (clear reference; retain) is the primary language on the Internet.

Sometimes, repetition of a key noun is preferred even when the reference is clear. In the following text, it is clear that it refers to the key noun gold , but when used throughout the text, the style becomes monotonous.

Improved text: Note where the key noun gold is repeated. The deliberate repetition creates interest and adds maturity to the writing style.

Gold , a precious metal, is prized for two important characteristics. First of all, gold has a lustrous beauty that is resistant to corrosion. Therefore, it is suitable for jewellery, coins and ornamental purposes. Gold never needs to be polished and will remain beautiful forever. For example, a Macedonian coin remains as untarnished today as the day it was made 23 centuries ago. Another important characteristic of gold is its usefulness to industry and science. For many years, it has been used in hundreds of industrial applications. The most recent use of gold is in astronauts’ suits. Astronauts wear gold -plated shields when they go outside spaceships in space. In conclusion, gold is treasured not only for its beauty but also its utility.

Pronoun + Repetition of key noun

Sometimes, greater cohesion can be achieved by using a pronoun followed by an appropriate key noun or synonym (a word with a similar meaning).

Transitions are like traffic signals. They guide the reader from one idea to the next. They signal a range of relationships between sentences, such as comparison, contrast, example and result. Click here for a more comprehensive list of Transitions (Logical Organisers) .

Test yourself: How well do you understand transitions?

Which of the three alternatives should follow the transition or logical organiser in capital letters to complete the second sentence?

Using transitions/logical organisers

Improve the coherence of the following paragraph by adding transitions in the blank spaces. Use the italicised hint in brackets to help you choose an apporpriate transition for each blank. If you need to, review the list of Transitions (Logical Organisers) before you start.

Using transitions

Choose the most appropriate transition from the options given to complete the article:

Overusing transitions

While the use of appropriate transitions can improve coherence (as the previous practice activity shows), it can also be counterproductive if transitions are overused. Use transitions carefully to enhance and clarify the logical connection between ideas in extended texts. Write a range of sentences and vary sentence openings.
