How much of your IELTS Writing score is Coherence & Cohesion?

25% — it is one of the four equally-weighted marking criteria.

What is the difference between coherence and cohesion?

Coherence is the logical order and clarity of ideas; cohesion is the linking words, referencing and paragraphing that connect the sentences.

How should you choose which linking word to use?

By the relationship you mean — adding, contrasting, cause/effect or sequencing — so the connector matches the actual logic.

What is 'referencing' and why does it help?

Using words like this, these, such or it to point back to earlier ideas so you avoid repeating the same nouns — a subtle, high-level cohesion skill.

Why can using lots of linking words lower your score?

The band descriptors penalise overuse or mechanical use of cohesive devices; a linker on every sentence reads as a template rather than natural flow.

IELTS Linking Words & Cohesion (Without Overdoing It)

Coherence & Cohesion is a quarter of your Writing score — here's how to link ideas naturally instead of stuffing in connectors.

The big picture

Coherence & Cohesion (25%)
- Linking words — Signal the relationship: add, contrast, cause, sequence
- Referencing — this, these, such, it — avoid repeating nouns
- Paragraphing — One clear idea per paragraph
- Don't overuse — Mechanical / overused connectors are penalised

What Coherence & Cohesion actually is

It's one of the four marking criteria in IELTS Writing — 25% of your score for that task. *Coherence* = your ideas are logically ordered and easy to follow. *Cohesion* = the sentences are connected with linking words, referencing and clear paragraphs.

💡

Real example: Two essays can share the same ideas, but the one where each paragraph flows into the next — and you never lose the thread — scores a band higher on this criterion alone.

🧠 Memory hook: Coherence = the ORDER makes sense. Cohesion = the GLUE between sentences.

A toolbox of linkers by function

Pick a linker by the relationship you mean: adding (furthermore, moreover, in addition), contrasting (however, on the other hand, whereas), cause/effect (therefore, as a result, consequently), sequencing (first, subsequently, finally). Using the right function word is what signals logic.

💡

Real example: Wrong function: 'The city is crowded, therefore it has great museums' (there's no cause there). Right: 'The city is crowded; nevertheless, it feels calm at night.' The linker must match the actual relationship.

🧠 Memory hook: Choose the linker by JOB: add, contrast, cause, or sequence. Wrong job = wrong word.

Referencing stops you repeating yourself

Words like this, these, such, it, they point back to something already said, so you don't repeat the same noun. Good referencing is a quiet, high-level cohesion skill examiners notice.

💡

Real example: Instead of 'Governments should fund public transport. Public transport reduces traffic,' write 'Governments should fund public transport, as **this** reduces traffic.' One word replaces a repeated phrase.

🧠 Memory hook: Said it once? Point back with 'this / these / such' instead of saying it again.

Overuse is penalised — natural beats mechanical

The band descriptors specifically warn against the overuse or mechanical use of cohesive devices. Starting every sentence with 'Moreover… Furthermore… In addition…' actually lowers your score. Aim for a range used naturally, not a linker bolted onto every line.

💡

Real example: Band-6 feel: 'Firstly… Secondly… Moreover… In conclusion…' on autopilot. Band-7+ feel: linkers appear only where the logic genuinely turns, and some sentences connect through meaning alone.

🧠 Memory hook: A linker on every line screams 'template'. Use them where the logic actually bends.
