The English Tutor Handbook · Volume 0037 · Series ID SETC-ETH-0037
A paragraph can contain correct grammar, relevant ideas and several linking words and still feel difficult to follow.
The reader knows what each sentence means.
The reader does not know why the sentences belong together.
Cohesion helps language connect on the surface. Coherence helps meaning connect in the reader’s mind. Strong English needs both.
This volume owns tutor-side cohesion and coherence diagnostics. It does not replace learner-facing paragraph, transition or essay-structure articles. Its job is to help tutors distinguish reference, lexical chains, conjunction, paragraph focus, idea progression and whole-text logic before deciding what kind of repair is needed.
Quick Read
- Do not diagnose coherence by counting linking words.
- Separate local cohesion from larger idea progression.
- Track reference, repetition, substitution, lexical chains and conjunctions.
- Ask what each sentence adds to the previous one.
- Ask what each paragraph contributes to the whole text.
- Teach transitions as relationships, not decorations.
- Use reverse outlines and sentence-function labels diagnostically.
- Test whether clarity survives when overt linking words are reduced.
1. Cohesion and Coherence Are Related but Different
Cohesion is visible in the language itself.
Pronouns refer back.
Key words repeat or vary.
Conjunctions signal relationships.
Coherence is the larger sense that the text makes one intelligible movement.
A text can be cohesive but incoherent if each sentence connects grammatically while the argument wanders.
2. The Linking-Word Trap
Students often learn cohesion as a list:
- however;
- therefore;
- moreover;
- in addition;
- on the other hand.
Adding these words does not create the relationships they name.
If two sentences do not genuinely contrast, however cannot rescue them.
3. Diagnose the Relationship First
Before choosing a connector, ask what the next sentence is doing.
- adding;
- contrasting;
- causing;
- qualifying;
- exemplifying;
- explaining;
- concluding;
- reframing.
Then decide whether an explicit connector is necessary.
4. Reference Cohesion
Pronouns and demonstratives can hold a text together or make it opaque.
Ask:
- What does this refer to?
- Could they refer to more than one noun?
- Has the referent become too distant?
- Would repeating the noun be clearer?
Reference is a coherence tool because readers must know what the text is still talking about.
5. Lexical Cohesion
Texts hold together through related vocabulary.
A paragraph about transport may use:
- commuters;
- ridership;
- public transport;
- rail capacity;
- journey time.
The words are not identical, but they occupy a shared semantic field.
6. Repetition Can Be Useful
Students often replace every repeated word because they believe repetition is weak style.
Strategic repetition can preserve the topic and prevent ambiguity.
Teach learners to ask whether variation improves the text or merely disguises the subject.
7. Substitution and Ellipsis
Writers avoid unnecessary repetition through substitution or omission.
But learners must understand what has been substituted or omitted.
In reading, this affects comprehension.
In writing, it affects clarity.
8. Sentence-to-Sentence Progression
Ask one diagnostic question repeatedly:
What does this sentence add that the previous sentence did not already do?
If the answer is “nothing”, the paragraph may be repeating rather than progressing.
9. Topic–Comment Progression
Readers follow more easily when familiar information helps introduce new information.
One sentence can end with an idea that becomes the starting point of the next.
Teach learners to inspect where attention moves.
10. Paragraph Focus
A coherent paragraph usually has a dominant job.
Give each sentence a function label.
- claim;
- evidence;
- explanation;
- example;
- qualification;
- consequence.
If one sentence cannot be attached to the paragraph’s job, it may belong elsewhere or may be unnecessary.
11. Paragraph-to-Paragraph Coherence
Even strong paragraphs can form a weak essay if their order does not create movement.
Use a reverse outline:
- P1 — define problem;
- P2 — explain mechanism;
- P3 — present constraint;
- P4 — evaluate trade-off;
- P5 — judge.
Now ask whether the sequence makes sense.
12. Coherence and Reader Questions
Imagine the reader asking after each paragraph:
- So what?
- Why?
- Compared with what?
- What evidence?
- What follows?
A coherent text anticipates enough of these questions to keep the reader moving.
13. Coherence and Knowledge
Sometimes a paragraph seems incoherent because the learner lacks the background model connecting the ideas.
SETC-ETH-0022’s Background-Knowledge Gate remains relevant.
14. Coherence and Sentence Complexity
A text may be logically coherent but difficult to follow because sentence structure hides the relationships.
SETC-ETH-0031’s Sentence Unpacking can reveal whether the problem is local syntax rather than whole-text organisation.
15. Coherence and Vocabulary
Vocabulary chains help readers track concepts.
But unnecessary synonym swapping can break those chains.
Teach lexical variation only where it preserves conceptual clarity.
16. The Remove-the-Linker Test
Delete an obvious transition word.
Does the relationship remain clear?
If not, the paragraph may depend too heavily on the connector instead of genuine conceptual progression.
17. The Sentence-Swap Test
Swap two sentences.
If nothing changes, the sequence may not be doing enough work.
If the logic breaks, ask why.
This makes order visible.
18. The Paragraph-Deletion Test
Remove one paragraph from the plan.
What does the reader lose?
If almost nothing changes, the paragraph may be redundant.
19. The One-Line Summary Test
Can the learner summarise what the whole paragraph is doing in one line?
If not, the paragraph may contain competing jobs.
20. Reading Coherence
In reading, ask learners to map:
- topic continuity;
- paragraph role;
- relationship shifts;
- reference chains;
- lexical fields.
This helps them reconstruct the writer’s design.
21. Writing Coherence
In writing, ask learners to design movement before polishing transitions.
What should the reader understand after paragraph one that was not true before?
What changes after paragraph two?
Coherence is designed across time.
22. Editing Coherence
Editing is not only grammar correction.
Ask whether pronouns remain clear, whether transitions match relationships, and whether sentence order supports logic.
23. Oral Coherence
Speaking also requires progression.
A fluent response can still wander.
Use a compact structure: point → reason → example → return.
Then vary it according to the question.
24. Cohesion in Listening
Listeners use cohesive signals to follow spoken discourse.
Teach recognition of contrast, correction, example and conclusion markers.
25. Do Not Over-Engineer Transitions
Not every sentence needs an explicit linker.
Strong progression can be carried by reference, repeated concepts and logical order.
26. Do Not Confuse Coherence With Predictability
A coherent text can surprise the reader.
The surprise still needs to be intelligible and earned.
27. Maren
Maren’s paragraphs are individually polished but two consecutive paragraphs repeat the same conceptual job.
The tutor uses a reverse outline and removes every transition word.
The repetition becomes obvious.
28. Iona
Iona follows sentence meaning but loses the writer’s whole argument.
The tutor asks for paragraph jobs and lexical chains rather than more sentence-level annotation.
29. Leonie
Leonie inserts too many explicit transitions under exam pressure because they feel safe.
The tutor trains relationship-first planning and a final cohesion check.
30. Three-Student Cohesion Lab
Give one paragraph.
- Student A tracks reference.
- Student B tracks lexical chains.
- Student C labels sentence progression.
Then compare which layer most contributes to the paragraph’s clarity.
31. Research Anchors
IES writing guidance emphasises explicit strategy instruction, sentence and paragraph development, reading–writing integration and formative assessment. Its secondary-writing materials include planning, revising and analysis of student work, all of which support treating coherence as an observable design problem rather than a vague stylistic judgement.
EEF literacy guidance similarly emphasises language comprehension, vocabulary, disciplinary language and purposeful writing. The practical tutor principle is to teach cohesion through actual relationships and coherence through meaningful progression, then verify both in authentic reading and writing.
32. Collision Boundary
- Essay Paragraph Structure remains learner-facing paragraph architecture guidance.
- SETC-ETH-0031 owns dense sentence relationships.
- SETC-ETH-0036 owns language awareness and terminology.
SETC-ETH-0037 owns tutor-side cohesion and coherence diagnostics: locating whether a text breaks through reference, lexical continuity, sentence progression, paragraph focus or whole-text movement before choosing the repair.
33. The Cohesion and Coherence Audit
- Can every pronoun be resolved?
- Do key concepts remain lexically visible?
- What relationship does each sentence add?
- Does the paragraph have one dominant job?
- Does every paragraph contribute something distinct?
- Would the logic survive if explicit linking words disappeared?
- Can the learner state the text’s progression in a reverse outline?
- Can the same clarity be rebuilt on a new topic?
English holds together not because every sentence wears a linking word, but because the reader can continuously answer: what are we talking about, what changed, and why does this next part belong here?
That is Cohesion and Coherence Diagnostics.
