Introduction

Writing essays for IELTS Task 2 can be one of the most challenging aspects of the exam. While many candidates focus on grammar and vocabulary, they often overlook the critical elements of coherence and cohesion – factors that contribute 25% to your overall writing score. This comprehensive guide provides proven strategies to craft logically structured, smoothly flowing essays that will help you excel in the IELTS writing section.

Whether you’re aiming for band 6.5 or targeting band 8+, mastering these principles will significantly enhance your writing quality and help you communicate your ideas more effectively to the examiner.

ℹ️ Info

Did you know? According to IELTS examiners, poor coherence and cohesion is one of the top three reasons why candidates score below band 7, even when their grammar and vocabulary are strong.

Understanding Coherence and Cohesion

What is Coherence?

Coherence refers to the logical connection and flow of ideas in your essay. A coherent essay presents arguments and information in a clear, organized manner that makes sense to the reader. It’s about the overall structure and how your ideas relate to each other and to the central thesis.

Key Elements of Coherent Writing

Logical organization of ideas and arguments
Clear paragraph structure with one main idea per paragraph
Consistent perspective throughout the essay
Relevant content that directly addresses the prompt
Smooth progression from one idea to the next

When an essay lacks coherence, readers (and IELTS examiners) struggle to follow your argument, regardless of how sophisticated your vocabulary or grammar might be. For guidance on properly addressing essay prompts, see our resource on Improving Task Response and Addressing the Prompt.

Why Cohesion Matters

Cohesion refers to the specific techniques and devices used to connect ideas within and between sentences and paragraphs. It’s about creating the “glue” that holds your essay together through linguistic connections.

Cohesive Element	Function	Examples
Reference words	Refer to previously mentioned ideas	it, this, these, they, such
Conjunctions	Connect ideas showing relationships	and, but, because, however, therefore
Lexical cohesion	Creating connections through related vocabulary	education, learning, students, teaching, academic
Substitution	Replacing words to avoid repetition	one, do so, the same
Ellipsis	Omitting words when meaning is clear from context	“Some people prefer tea; others [prefer] coffee.”

Effective cohesion makes your writing flow smoothly and helps guide the reader through your argument. For comprehensive guidance on using linking words effectively, check our specialized guide on Linking Words and Phrases for IELTS Writing.

IELTS Task 2 Writing Essentials

Key Task Requirements

Before focusing on coherence and cohesion, ensure you understand the fundamental task requirements:

Write a formal academic essay of at least 250 words (ideally 260-290 words)
Address all parts of the question
Organize your ideas into paragraphs with a clear introduction and conclusion
Complete the task in around 40 minutes
Demonstrate range and accuracy in both grammar and vocabulary

For a detailed breakdown of these requirements, explore our guide on Understanding the IELTS Writing Task 2 Format.

Avoiding Common Pitfalls

Several mistakes commonly undermine coherence and cohesion in IELTS essays:

Unclear paragraph divisions - Mixing multiple ideas in one paragraph or splitting single ideas across multiple paragraphs
Overusing simple linking words - Repeatedly using basic connectors like “and,” “but,” and “so” instead of varied transitions
Jumping between ideas - Failing to establish clear connections between sentences and paragraphs
Inconsistent use of referencing - Using pronouns ambiguously or incorrectly
Mechanical transitions - Using linking words without logical relationships between ideas

⚠️ Warning

Common Mistake: Many candidates believe that simply inserting linking words like “furthermore” or “however” automatically creates cohesion. Without logical connections between the ideas themselves, these words become mechanical and ineffective.

Strategies for Coherent Essays

The Importance of Planning

Spending 5-7 minutes planning your essay before writing is perhaps the single most important factor in achieving coherence. A well-planned essay has a clear direction and structure from the outset.

  Effective Planning Process
Analyze the question thoroughly (identify key components and requirements)
Decide your position/approach (particularly for opinion or discussion essays)
Brainstorm 2-3 main points that directly address the question
Select supporting examples/evidence for each main point
Create a paragraph-by-paragraph outline with clear topic sentences
Note key linking phrases you’ll use between paragraphs

This structured planning process creates a roadmap for your essay, ensuring logical progression and coherent development. For detailed planning strategies, see our comprehensive guide on Effective Essay Planning Techniques.

Linking Your Ideas

Once you have your main ideas planned, focus on creating logical connections between them:

Use explicit signposting to guide the reader through your argument
Create clear topic sentences that connect to your overall thesis
Use preview and review techniques to connect paragraphs:
- End paragraphs by hinting at the next idea (preview)
- Begin paragraphs by referencing previous points (review)
Maintain idea hierarchies - distinguish between main ideas and supporting details

Weak connection between paragraphs: “Social media has many negative effects on teenagers. It causes addiction. Education is important for young people. Schools should teach digital literacy.”

Strong connection between paragraphs: “Social media has several negative effects on teenagers, particularly its addictive nature that can impact mental health. Given these challenges, educational institutions play a crucial role in addressing this issue. Schools should incorporate digital literacy into their curriculum to help students navigate social media responsibly.”

Enhancing Cohesion in Your Writing

Effective Use of Connective Words

Cohesive devices serve different functions in connecting ideas. Use them appropriately based on the relationship between your ideas:

Types of Cohesive Devices

1. Adding information:

Furthermore
In addition
Moreover
Additionally
What’s more

2. Contrasting ideas:

However
Nevertheless
Nonetheless
Despite this
On the other hand
In contrast

3. Showing cause and effect:

Therefore
Consequently
As a result
Thus
Hence
For this reason

4. Sequencing ideas:

Firstly/Secondly/Finally
Initially/Subsequently/Eventually
To begin with/Following this/Lastly
First and foremost/In addition/In conclusion

5. Exemplification:

For instance
For example
To illustrate
Such as
Namely
A case in point is

Remember that effective cohesion comes not just from using these words, but from using them appropriately to show the true logical relationship between your ideas.

Maintaining Consistent Tense and Style

Consistency in language use is crucial for coherent writing:

Tense consistency - Maintain appropriate tense throughout paragraphs unless there’s a logical reason to switch
Pronoun consistency - Be clear about what pronouns (it, they, this, these) refer to
Stylistic consistency - Maintain a formal academic tone throughout
Terminology consistency - Use the same terms for key concepts rather than switching between synonyms for crucial terms

💡 Tip

Language Consistency Tip: When referring to the same concept throughout your essay, use the same term consistently for clarity. While vocabulary variety is important, changing terminology for central concepts can confuse the reader. For example, if discussing “remote work,” don’t switch between “telecommuting,” “working from home,” and “distance working” for the same concept.

Model Essay Analysis: Coherence and Cohesion in Action

Let’s analyze how coherence and cohesion work in a high-scoring sample essay responding to the question: “The only reason for people working hard is to earn money. To what extent do you agree or disagree?”

Coherence Analysis

Clear overall structure:

Introduction clearly presents the topic and the writer’s position
Each body paragraph focuses on one distinct motivation beyond money
Conclusion effectively synthesizes the main arguments

Logical progression of ideas:

First acknowledges money as an important motivation (showing balance)
Then presents three alternative motivations in order of importance
Builds argument from individual motivations (personal fulfillment) to broader social motivations (family responsibilities)

Strong paragraph organization:

Each paragraph begins with a clear topic sentence stating the main alternative motivation
Supporting explanations and examples develop each motivation
Paragraphs have appropriate length and development

Cohesion Analysis

Effective use of cohesive devices:

Sequential markers: “Firstly,” “Secondly,” “Moreover” to organize main points
Concluding marker: “In conclusion” to signal the final summary
Emphasis markers: “While,” “undoubtedly,” “essential” to show relative importance

Reference and substitution:

Consistent reference to the main topic: “hard work,” “professional lives,” “work ethic”
Appropriate pronoun use: “Many people derive…” followed by “The intrinsic rewards…”
Substitution to avoid repetition: “These benefits” instead of repeating specific rewards

Lexical cohesion:

Related vocabulary around work: “professional lives,” “career advancement,” “work ethic”
Related vocabulary around motivation: “drive,” “inspire,” “motivator”
Word families: “professional/profession,” “motivate/motivation/motivator”

This analysis demonstrates how a high-scoring essay maintains both logical structure (coherence) and linguistic connections (cohesion) throughout. For more examples of strong essays, see our guide on Analyzing Model Essays for IELTS Writing.

If each paragraph has a clear central idea
Whether transitions between paragraphs feel natural
How effectively you’ve used cohesive devices

ℹ️ Info

Feedback Focus: When seeking feedback, specifically ask about the logical flow of your ideas rather than just grammar and vocabulary. Ask questions like “Does my argument progress logically?” and “Are the connections between my paragraphs clear?”

Advanced Coherence and Cohesion Techniques

Creating Paragraph Unity

Each paragraph should revolve around a single main idea, with all sentences supporting it:

Strong topic sentences - Begin each paragraph with a clear statement of the main idea
Supporting details - Follow with explanations, examples, or evidence
Concluding or transitional statement - End with a sentence that either wraps up the point or bridges to the next paragraph

Strong paragraph structure:

[Topic Sentence] “Personal fulfillment and job satisfaction are crucial factors that motivate people to work hard beyond financial gain.”

[Supporting Explanation] “Many people derive a sense of accomplishment and pride from their work.”

[Specific Example] “For instance, professionals such as doctors, teachers, and artists often pursue their careers out of passion and a desire to make a meaningful impact.”

[Further Development] “The intrinsic rewards of helping others, creating something unique, or achieving personal goals can be powerful motivators that go beyond mere financial gain.”

[Transition to Next Paragraph] “Beyond personal satisfaction, professional advancement also drives many individuals to excel in their work.”

Creating Thematic Threads

Strong essays maintain thematic consistency by weaving key ideas throughout:

Keyword threading - Repeat important terms and concepts strategically
Conceptual echoing - Refer back to earlier points as you develop your argument
Semantic fields - Use vocabulary from related word groups throughout
Question referencing - Tie your points back to the original prompt regularly

This technique creates a sense of unity and purpose throughout your essay, showing the examiner that all your points contribute to addressing the question.

Effective Introduction and Conclusion

Your introduction and conclusion play crucial roles in establishing coherence:

Element	Function	Example
Introduction
Context statement	Establishes the general topic	“In contemporary society, people’s motivation for working hard is often scrutinized.”
Specific focus	Narrows down to the specific question	“While financial reward is commonly cited as the primary incentive, the motivations behind professional diligence are more complex.”
Thesis statement	States your position clearly	“This essay will argue that although monetary gain is significant, several other important factors drive people to excel in their professional lives.”
Conclusion
Restatement	Recalls your main argument	“As demonstrated, while earning money is undoubtedly a significant motivator for hard work, it is certainly not the sole reason.”
Summary	Briefly recalls main points	“Personal fulfillment, career advancement, and social responsibilities also play vital roles in driving individuals to excel.”
Final thought	Provides closure and broader context	“Therefore, it is essential to recognize the multifaceted nature of motivation in the workplace.”
