What is Cohesion and Coherence?
Cohesion and coherence are key to clear, connected writing. Cohesion uses linguistic devices (pronouns, connectors) to link sentences; coherence ensures ideas flow logically and make sense.
Cohesion uses connectors and pronouns to link sentences; coherence ensures all ideas connect logically with a clear overall meaning and structure.
- •Pronouns linking to nouns
- •Transition words
- •Repeated keywords
- •Ellipsis (omitting words)
- •Ideas in logical order
- •Topic sentences
- •Unified theme
- •Supporting details
Step-by-step worked examples
Improve cohesion: 'The book was interesting. Sarah enjoyed reading the book.'
Problem: 'book' repeated, awkward Cohesive fix: Use pronoun 'it' Improved: 'The book was interesting. Sarah enjoyed reading it.'
Analyze coherence in: 'I like pizza. Elephants are large. My homework is done.'
Problem: Ideas unrelated, no logical flow, no unified theme No coherence: Sentences don't support a central point Fix: Group related ideas or create a central topic
Create a coherent paragraph on climate change.
Topic sentence: state main idea Body 1: causes Body 2: effects Body 3: solutions Conclusion: restate theme → logical flow + unified meaning

Common mistakes
Overusing the same pronoun, causing ambiguity. — Correct: Use pronouns when reference is clear; use names when needed.
Jumping between unrelated ideas without transitions. — Correct: Use discourse markers to signal relationships (furthermore, however, etc.).

Writing a series of facts without a unified theme. — Correct: Every paragraph should support one central idea.
