Cohesive Devices — Making Writing Flow Like a Native Speaker

Imagine Ravi, a senior consultant at Infosys, writing a project proposal for a client in London. His grammar is perfect and his vocabulary is sophisticated, yet the client finds the report “choppy” and hard to follow. This happens because Ravi’s sentences, while individually correct, aren’t glued together. In advanced English, especially for IELTS, UPSC, or corporate communication, it isn’t enough to write correct sentences; you must master cohesion—the art of making your ideas stick together so the reader never has to pause to figure out what you are talking about.

1. The Five Systems of Cohesion

Cohesion acts as the “internal glue” of a paragraph. While discourse markers (like however or moreover) signal the logic, cohesive devices create the structural network.

Five Systems of Cohesion with Examples

System	Definition	Example
Reference	Pointing back to a person or thing mentioned earlier.	Neha bought a car. It is red.
Substitution	Replacing a noun or verb with a placeholder to avoid repetition.	I need a new phone. I’ll buy this one.
Ellipsis	Omitting a word because the context makes it clear.	Arjun is coming to the party, and Priya [is coming] too.
Lexical	Linking sentences through word choice (synonyms or related terms).	The monsoon was heavy. The downpour flooded Mumbai.
Conjunction	Using connective words and phrases (discourse markers) to signal logical relationships.	However, the plan succeeded. Furthermore, profits increased.

2. Reference Chains: Tracking Nouns

Reference chains are the most common way to maintain flow. In Indian English writing, we often repeat the noun too many times (e.g., “The student... the student... the student”), which sounds mechanical. Instead, follow this progression from indefinite to definite:

Reference Chain Progression

First Mention (Indefinite)	Subsequent Mention (Definite/Demonstrative)	Pronoun Reference
A start-up was launched in Bangalore.	The company focuses on AI.	It raised ₹1 crore in funding.
Several students protested.	These individuals demanded a re-test.	They met the Vice Chancellor.
An antique vase was broken.	This irreplaceable item was lost.	It was 200 years old.

3. Lexical Cohesion: The Semantic Field

Lexical cohesion is about choosing words that belong to the same “family.” This creates a semantic field—a sense that every word in the paragraph is working toward the same theme.

• Synonyms: Instead of repeating “beautiful,” use “stunning,” “picturesque,” or “exquisite.”
• Hyponyms (General to Specific): If you are writing about “vehicles,” you might use “trucks,” “sedans,” and “motorcycles” in the following sentences to keep the reader engaged.
• Antonyms: Using opposites to highlight a contrast. “While the urban areas are developing rapidly, rural regions remain neglected.”
• Collocations: Words that frequently occur together in a specific sequence. For example, if the theme is ”Education,” phrases like ”academic achievement,” “primary education,” or ”curriculum development” create strong cohesive links.

4. Discourse Markers vs. Referential Cohesion

A common mistake for IELTS aspirants is over-relying on discourse markers (Furthermore, In addition, Consequently) while neglecting reference chains. Native speakers use discourse markers sparingly—usually only when they need to signal a shift in logic. Referential and lexical cohesion, however, operate in almost every sentence to maintain the thread.

A high-scoring essay uses both. If you only use discourse markers, your writing feels like a list. If you use reference chains correctly, your writing feels like a story.

5. Cohesion Across Paragraphs: The Old-New Principle

To connect two paragraphs, use the “Old-New Principle.” Start the first sentence of a new paragraph with “old” information (something mentioned at the end of the previous paragraph) before introducing “new” information.

This “bridge” ensures the reader doesn’t feel a sudden jump between topics.

6. Diagnosing Cohesion Problems

Choppy vs. Cohesive Writing

❌ Choppy/Repetitive Paragraph	✅ Cohesive Rewrite	Why?
Karan joined Infosys. Karan liked the work environment at Infosys. The work environment was friendly. Karan decided to stay at Infosys for years.	Karan joined Infosys. The firm’s work environment was so friendly that he decided to stay there for years.	Uses lexical cohesion (the firm), reference (he/there), and subordination (combining the sentences using 'so... that').

Common Mistakes by Indian Learners

Many learners struggle with “Ambiguous Reference,” where it isn’t clear what ‘it’ or ‘this’ refers to.

Basic vs. Advanced Cohesion

⚠️ Basic / Repetitive	✅ Advanced / Cohesive	Why?
Ravi told Amit that he had won the lottery.	Option 1 (if Ravi won): Ravi informed Amit that he himself had won the lottery. Option 2 (if Amit won): Ravi congratulated Amit on winning the lottery.	In the ambiguous version, ’he’ could refer to either Ravi or Amit. The advanced rewrite resolves this using an intensive pronoun—a pronoun used to emphasize its antecedent ('himself')—to clarify the subject.
The hospital was built in 1920. The hospital has since treated thousands of patients.	The hospital was built in 1920. The institution has since treated thousands of patients.	Replacing the repeated ’hospital’ with ’institution’ avoids tedious repetition while maintaining clear lexical cohesion.
Education is key. Furthermore, it is important.	Education is key. This foundation allows individuals to grow.	‘Furthermore’ adds no new information; ‘This foundation’ links back to ‘key’.

Summary

Cohesion is what transforms a collection of sentences into a professional piece of writing. By using reference, substitution, ellipsis, and lexical variety, you guide your reader through your thoughts effortlessly.

• Use Reference (this, that, they) to point back to previous nouns.
• Use Substitution and Ellipsis to avoid repetitive phrasing.
• Use Lexical Cohesion (synonyms and hyponyms) to avoid boring repetition.
• Balance Discourse Markers (conjunctions) with referential cohesion to ensure flow.
• Follow the Old-New Principle to bridge the gap between paragraphs.
• Avoid Ambiguous References—always ensure ’it’ or ’this’ has a clear antecedent (the noun or idea the pronoun refers back to).

Key takeaway: Before submitting a report or essay, read it aloud. If it sounds like a list of separate facts, add “summary nouns” (this issue, this trend, this move) to link your ideas. Practise by highlighting all the pronouns in a newspaper article to see how the author tracks their subjects!
