COHESION VS. COHERENCE
Cohesion is the visible “glue” that
links words and sentences; coherence is the reader’s sense that the
ideas form a meaningful, logical whole. A text can be cohesive but incoherent,
or coherent despite limited cohesion.[web.unica][files.eric.ed]

Examples |
Pronouns, repetition, connectives, substitutions |
Topic development, relevance, sequence of ideas |
|
Main question |
How are these parts formally connected? |
Do the ideas make sense together? |
Cohesion uses explicit cues such as pronouns, repeated words, and
connectors like because, therefore, and however. Coherence
depends on those cues but also on background knowledge, context, and the
reader’s ability to infer relationships between ideas.[files.eric.ed][acikders.ankara.edu]
Cohesion in text analysis
Cohesive devices include:
- Reference: “Ani bought a book. She read it
all night.” — She refers to Ani.
- Lexical repetition: “The storm damaged the roof. The storm
also knocked down trees.”
- Connectives: “He was tired; therefore, he went
to bed.”
- Substitution/ellipsis: “Would you like tea?” “Yes, I’d like one.”
/ “I will go if you will.”
These devices help readers track participants, topics, and relationships
across sentences.[files.eric.ed][eapfoundation]
Coherence in text analysis
Coherence concerns whether the text has a clear central idea and whether
its sentences are relevant and logically ordered. It is not always marked by
explicit connectors; readers infer it from content and context.[web.unica][ub]
Example of a coherent paragraph:
Remote work has changed how teams communicate. Employees now rely more
on written updates, video meetings, and shared documents. As a result, clear
writing has become an important workplace skill.
The ideas move logically from a general change to its effects and then
to a conclusion. There is some cohesion—as a result—but the coherence
comes mainly from the unified topic and logical progression.[eapfoundation][awec.ntu.edu]
Examples showing the contrast
Cohesive but not coherent
My brother likes football. Footballs are usually round. Round objects
include oranges. Oranges contain vitamin C.
The text uses repetition and related nouns, so it is fairly cohesive.
But it does not develop one clear point, so readers may find it incoherent.[web.unica][journal.unnes.ac]
Coherent but not highly cohesive
Husband take gun shoot. Go outside die. Call police. Emergency 911.
This lacks polished grammatical linking, but a reader can reconstruct a
sequence of events and understand the overall situation. It is therefore
relatively coherent despite weak cohesion.[journals.sagepub]
In analysis
When analyzing a text, ask:
- For cohesion: Which pronouns, repetitions,
substitutions, and connectors link clauses or sentences?
- For coherence: What is the main idea? Are all sentences
relevant? Does the order of ideas help the reader understand the message?
In short, cohesion is about surface connectivity, while coherence
is about underlying meaningfulness.[acikders.ankara.edu][uni-saarland]
