Cohesion and Coherence: Definition, Example, and Exercises

Cohesion and coherence are two important parts of good writing. They help your sentences and ideas flow smoothly and make your writing easy to understand. Whether you are writing a paragraph, an essay, or answering questions, knowing how to use cohesion and coherence can really improve your work. These skills are very useful in school exams, English grammar tests, writing sections of IELTS, TOEFL, and other competitive exams where clear writing is important. 

In this blog, we will learn what cohesion and coherence mean, see simple examples, and explore the best ways to use them. You will also find an easy exercise to help you practice and become more confident in writing.

What is Cohesion?

In English writing, cohesion refers to the way sentences and paragraphs are connected at a grammatical and lexical (vocabulary) level, creating a smooth and interconnected flow of ideas. It’s like the ‘glue’ that holds your writing together, ensuring that the relationships between different parts of your text are easy for the reader to follow.

Important Features of Cohesive Writing:

• Smooth Transitions: One idea flows naturally into the next.
• Clear Relationships: The reader can understand how each idea connects to the next.
• No Abrupt Jumps: Sentences don’t feel random or out of place.
• Less Repetition: Instead of repeating the same words, we use pronouns or similar words.

How Do We Create Cohesion?

Writers use cohesive devices — special tools that help connect ideas. Here are the most common ones:

Cohesive Device	What It Does	Example
Pronouns (Referencing)	Replaces nouns to avoid saying the same name or word again and again.	‘Ravi has a bike. He rides it every day.’
Conjunctions / Linking Words	Join sentences and show how ideas are connected (add, contrast, result).	‘It was cold, so she wore a jacket.’
Repetition / Synonyms	Repeating key words or using similar words to stay on the same topic.	‘Water is precious. We must save this resource.’
Substitution	Replacing a longer phrase or noun with a shorter word.	‘I need a pen. Can I borrow one?’
Ellipsis	Leaving out words that are already understood from the sentence.	‘He can play the guitar, and she can too.’ (No need to repeat ‘play the guitar’)

What is Coherence?

Coherence in writing refers to the logical and rational organization of ideas, making the overall message clear, understandable, and easy for the reader to follow. While cohesion is about the grammatical and lexical connections between sentences, coherence is about the meaningful and logical connections among ideas, paragraphs, and the entire text.

Think of it as the ‘sense’ or the ‘blueprint’ of your writing. Even if all your sentences are grammatically correct and linked together (cohesive), your writing won’t be coherent if the ideas jump around randomly, or if there’s no clear progression of thought.

Important Features of Coherent Writing:

• Logical flow: Ideas come in the right order (step-by-step or cause to effect).
• Clear purpose: The main message or topic is easy to see and stays the same.
• Unified writing: Everything supports the main idea; nothing goes off-topic.
• Easy to follow: The reader doesn’t get lost or confused while reading.

How Do We Create Coherence?

To make your writing easy to understand and follow, you need to organize your ideas clearly. This is called coherence. Below are some simple and effective ways to create coherence in your writing:

Method	Explanation	Example
Logical Order of Ideas	Put ideas in a way that makes sense, like a story or steps.	‘First we went to the park, then we played, and finally we ate.’
Clear Topic Sentence	Begin each paragraph with a sentence that tells the main idea.	‘Pollution is a big problem in cities.’
Unified Paragraph	All sentences in a paragraph must relate to one main idea.	Don’t talk about movies in a paragraph about food.
Consistent Point of View	Use the same voice (I, he, they) throughout your writing.	Don’t switch from ‘I’ to ‘they’ randomly.
Thesis Statement (Essays)	In essays, start with one strong sentence that tells what your writing is about.	‘Exercise is important because it keeps us healthy and happy.’
Transitions Between Ideas	Use words or short phrases to move from one idea to the next smoothly.	‘First,’ ‘Then,’ ‘As a result,’ ‘On the other hand,’ etc.

Most Effective Ways to Create Cohesion in a Paragraph

Cohesion means making sure all your sentences in a paragraph are connected and flow smoothly. Here are some easy ways to do that:

Way to Create Cohesion	Simple Explanation	Example
Use Pronouns	Use words like he, she, it, they to avoid repeating names.	Sara is kind. She helps everyone.
Use Linking Words	Use words like and, but, because, so to join ideas.	‘It was raining, so we stayed inside.’
Repeat Important Words	Repeat key words or use similar words (synonyms) to stay focused.	‘Dogs are loyal. These animals love their owners.’
Use Substitution	Replace a word with another one to avoid repetition.	‘I need a pen. Can I borrow one?’ (Instead of saying ‘pen’ again)
Use Ellipsis	Leave out words that the reader can understand from the context.	‘She likes apples, and he does too.’ (Ellipsis leaves out ‘like apples’)

Most Effective Ways to Create Coherence in a Paragraph

Coherence means your ideas in a paragraph are clear and follow each other in a logical order. Here are some easy ways to make your paragraph coherent:

Way to Create Coherence	Simple Explanation	Example
Start with a Clear Topic Sentence	Begin the paragraph by saying what it is about.	‘Exercise is good for health.’
Arrange Ideas Logically	Put your ideas in order that makes sense (time, cause-effect, importance).	‘First, exercise makes your heart stronger. Then, it improves mood.’
Stick to One Main Idea	Make sure every sentence supports the main idea of the paragraph.	Don’t talk about food in a paragraph about exercise.
Use Transition Words	Use words like next, then, because, for example, to connect ideas.	‘Exercise is fun. For example, you can play football or swim.’
Keep the Same Point of View	Use the same person or tense throughout the paragraph.	Don’t suddenly switch from ‘I’ to ‘they’ or from past to present.

Difference Between Cohesion and Coherence

Understanding the difference between cohesion and coherence helps you write better and clearer paragraphs. Here’s a simple comparison to help you:

Aspect	Cohesion	Coherence
Meaning	How sentences are connected using grammar and words.	How ideas are organized logically and clearly.
Focus	Sentence-level connection (words and grammar).	Whole text or paragraph makes sense and flows well.
Purpose	To link sentences smoothly.	To make the writing easy to understand.
Examples	Using pronouns, conjunctions, linking words.	Arranging ideas in order, clear topic sentences.
Result	Writing feels joined and smooth.	Writing makes sense and is easy to follow.
Helps Reader	See how sentences relate to each other.	Understand the main message and ideas clearly.

Rules for Use: Cohesion and Coherence

To make your writing clear and easy to understand, follow these simple rules for cohesion and coherence:

Rule	Explanation	Example
1. Use Pronouns Carefully	Replace nouns with pronouns to avoid repetition but be clear about who or what you mean.	‘Ravi went to school. He was happy.’
2. Use Linking Words	Use words like and, but, because, so to connect ideas smoothly.	‘It was cold, so we wore jackets.’
3. Repeat Important Words or Use Synonyms	Repeat key words or use similar words to keep the paragraph focused.	‘The sun is hot. This heat makes plants grow fast.’

Answer Key: Exercise 4 – Identifying Coherence Issues

Coherence Problems:

1. Lack of logical connection: The sentences jump randomly from weather to personal preference, to traffic, to a hobby, and then back to weather. There’s no single unifying theme or progression of ideas.
2. No topic sentence: There’s no central idea introduced at the beginning that the rest of the sentences support.
3. Irrelevant information: Most sentences are unrelated to each other.

Suggestions for Improvement:

1. Choose a single topic: Decide on one main topic for the paragraph (e.g., ‘a sunny day,’ ‘my hobbies,’ ‘challenges of commuting’) and ensure all sentences relate to it.
2. Create a topic sentence: Start with a sentence that introduces the main idea.
3. Remove unrelated sentences: Delete sentences that don’t fit the chosen topic.
4. Add cohesive devices: Once the ideas are logical, use linking words and pronouns to connect them.

Exercise 5: Building a Coherent Paragraph
