Cohesive Devices Used Sparingly

When linkers help vs. when they crowd

Topic & Why It Matters

Cohesive devices are the words and structures that connect ideas: linkers, pronouns, reference phrases, repeated key terms, and cause-effect grammar. They matter because IELTS gives a separate Coherence and Cohesion score, and the examiner must be able to follow your argument without guessing.

Candidates lose marks when they treat cohesion as a list of fancy connectors. Strong writing uses enough signposting to guide the reader, but not so much that every sentence sounds like a memorised template.

Knowledge Points

Cohesion is logic first, linkers second
Examiners reward writing that is easy to follow. Linkers help only when the relationship between ideas is real: cause, contrast, example, result, addition, or conclusion.
Too many linkers can lower the score
A sentence that starts with 'Moreover', 'Furthermore', or 'In addition' every time sounds memorised and mechanical. Band 7+ writing uses a mixture of reference words, repeated key nouns, pronouns, and sentence logic.
Referencing is a powerful cohesive device
Words such as 'this', 'these services', 'such routes', and 'this argument' connect sentences without heavy signposting. They show the examiner exactly which previous idea the new sentence is developing.
Cohesion must work inside and between paragraphs
A topic sentence links the new paragraph to the essay question, while the following sentences link to each other. Paragraphs that are individually clear but disconnected still lose Coherence and Cohesion marks.
Use contrast signals only for real contrast
Words like 'however', 'whereas', and 'nevertheless' should mark a genuine shift in direction. Using them for another similar point confuses the reader and weakens the argument.
Lexical chains create quiet cohesion
Repeating a controlled set of key terms - for example 'public transport', 'services', 'bus lane', 'train line', and 'fares' - is clearer than replacing every noun with a forced synonym.

Structure Template

Plan cohesion at essay level before choosing individual linkers. Each paragraph should have one clear job and one clear connection to the surrounding argument.

Essay StageCohesion FunctionWhat to Do
IntroductionSet the argument routeParaphrase the prompt and state a thesis that previews the main relationship between the views. One concession marker such as 'While' is often enough.
Body paragraph 1Develop the first sideStart with a topic sentence. Use one example marker if needed, then connect the evidence to its effect with a result phrase such as 'therefore' or 'as a result'.
Body paragraph 2Shift or extend the argumentUse a contrast signal only if the paragraph genuinely moves away from the previous view. Build cohesion with reference words like 'these services' or 'this approach'.
ConclusionReturn to the thesisUse a short concluding phrase, restate the position, and avoid introducing a fresh linker-heavy argument in the final sentence.
Cohesion rule: A cohesive device should make the relationship between ideas clearer. If it only makes the sentence sound more formal, remove it.

Three-Question Cohesion Audit

QuestionAction
What relationship am I showing?Choose a device only after naming the relationship: contrast, result, example, addition, condition, or conclusion.
Can a reference word do the job?Use 'this', 'these services', 'such measures', or a repeated key noun when the sentence continues the same idea.
Is the paragraph still controlled by one idea?If a linker is hiding a jump to a new topic, split the paragraph or rewrite the topic sentence.

Common Pitfalls

MistakeCorrection
Starting every sentence with a linkerWeak: 'Firstly... Moreover... Furthermore... In addition...' Strong: use one clear topic sentence, then connect ideas with pronouns, repeated key nouns, and cause-effect grammar.
Using a contrast word without contrastDo not write 'However' before another supporting example. Use 'For example', 'This also means that', or no linker if the sentence naturally continues the same idea.
Replacing key nouns with unclear synonymsIf the topic is public transport, it is fine to repeat 'public transport' or use precise references such as 'these services'. Do not force vague synonyms like 'this aspect'.
Writing paragraphs that do not connect to the thesisEach topic sentence should echo the prompt and the thesis. If the thesis is about productivity, a paragraph about happiness needs an explicit productivity link.
Using memorised sequence labels for Task 2'Firstly' and 'Secondly' are acceptable but often basic. Prefer topic-led openings such as 'The strongest argument for road investment is...' or 'In dense cities, public transport...'.

Practice Prompt

Set a 40-minute timer. Before writing, plan which paragraph will concede, which will contrast, and where a reference word can replace a heavy linker.

You should spend about 40 minutes on this task.

Some people think governments should spend more money on public transport, while others believe road networks should receive more investment.

Discuss both views and give your own opinion.

Write at least 250 words.

Planning reminder: Do not choose linkers before the logic is clear. First decide whether the next sentence adds, contrasts, explains, or gives a result.

Model AnswerBand 7.5+ · 255 words

Debates about transport spending often centre on whether public money should prioritise buses, trains, and metro systems or the roads used by private cars and freight. While better roads can reduce bottlenecks in some areas, I believe public transport deserves greater investment because it moves more people efficiently and makes cities less dependent on private vehicles.

The case for road investment is strongest where existing routes are unsafe or seriously congested. In rural districts, for example, a poorly maintained road may delay ambulances, increase delivery costs, and isolate residents from work or education. Upgrading such routes can therefore bring immediate economic and social benefits. This argument is reasonable, especially when a road serves communities with few realistic transport alternatives.

However, in dense towns and cities, public transport usually creates stronger long-term gains. A full bus lane or train line can carry far more passengers than the same space filled with individual cars, so investment in these services reduces congestion rather than simply making room for more traffic. It also gives low-income residents, students, and older people reliable access to jobs and public services. If fares remain affordable and services run frequently, the benefits extend beyond convenience to cleaner air and a more equal city.

For these reasons, road repairs should not be ignored, particularly outside major urban centres. Nevertheless, the main priority should be public transport, with road spending reserved for safety and essential connectivity. This approach links each project to a clear purpose instead of treating every journey as another reason to expand roads.

Annotated Commentary

Each paragraph is quoted, then broken down by examiner criteria. Notice that cohesion comes from reference, paragraph direction, and sentence logic, not from a long chain of obvious linking words.

[ Paraphrase + thesis ]Paragraph 1 - Introduction
Debates about transport spending often centre on whether public money should prioritise buses, trains, and metro systems or the roads used by private cars and freight. While better roads can reduce bottlenecks in some areas, I believe public transport deserves greater investment because it moves more people efficiently and makes cities less dependent on private vehicles.
Paraphrase'transport spending', 'public money', and 'private cars and freight' rephrase the prompt without copying it
Thesis'I believe public transport deserves greater investment' gives a direct position
Cohesive device'While' introduces a limited concession before the writer's judgement
Complex grammar'whether public money should prioritise...' uses a noun clause to frame the debate
Lexical upgrade'bottlenecks', 'efficiently', and 'dependent on private vehicles' are precise transport terms
[ Topic sentence ]Paragraph 2 - Road-investment view
The case for road investment is strongest where existing routes are unsafe or seriously congested. In rural districts, for example, a poorly maintained road may delay ambulances, increase delivery costs, and isolate residents from work or education. Upgrading such routes can therefore bring immediate economic and social benefits. This argument is reasonable, especially when a road serves communities with few realistic transport alternatives.
Topic sentence'The case for road investment is strongest...' clearly limits the paragraph to the first view
Cohesive device'for example' introduces evidence, while 'therefore' marks the result of upgrading roads
Reference'such routes' and 'This argument' connect back to the same road example without repeating the full noun phrase
Complex grammar'where existing routes are unsafe...' and 'when a road serves...' add precise conditions
Lexical upgrade'seriously congested', 'isolate residents', and 'transport alternatives' make the support concrete
[ Contrast + support ]Paragraph 3 - Public-transport view
However, in dense towns and cities, public transport usually creates stronger long-term gains. A full bus lane or train line can carry far more passengers than the same space filled with individual cars, so investment in these services reduces congestion rather than simply making room for more traffic. It also gives low-income residents, students, and older people reliable access to jobs and public services. If fares remain affordable and services run frequently, the benefits extend beyond convenience to cleaner air and a more equal city.
Topic sentence'public transport usually creates stronger long-term gains' states the stronger side of the thesis
Cohesive device'However' marks a genuine shift from road spending to public transport
Reference'these services' refers back to bus lanes and train lines, creating cohesion without another heavy linker
Complex grammar'If fares remain affordable...' uses a conditional clause to qualify the claim
Lexical upgrade'long-term gains', 'reliable access', and 'cleaner air' develop the argument with precise outcomes
[ Conclusion ]Paragraph 4 - Conclusion
For these reasons, road repairs should not be ignored, particularly outside major urban centres. Nevertheless, the main priority should be public transport, with road spending reserved for safety and essential connectivity. This approach links each project to a clear purpose instead of treating every journey as another reason to expand roads.
Thesis restated'the main priority should be public transport' repeats the position in fresh wording
Cohesive device'For these reasons' summarises the body logic; 'Nevertheless' returns from concession to judgement
Complex grammar'with road spending reserved for safety...' adds a controlled qualifying phrase
Lexical upgrade'essential connectivity' and 'clear purpose' make the policy judgement more specific
No new ideaThe conclusion does not introduce another example; it ties the two spending choices together

Self-Check

Answer these from memory before looking back. If you cannot answer all, re-read the relevant section.

  1. Why can too many linking words reduce Coherence and Cohesion rather than improve it?
  2. What is the difference between 'however' and 'therefore'?
  3. Replace the second 'Moreover' in this sequence: 'Public transport reduces traffic. Moreover, it carries more people in less space. Moreover, it helps low-income residents reach work.'
Answers: (1) Too many linkers sound mechanical and may hide weak logic; cohesion should come from clear relationships, reference words, and controlled paragraphing. (2) 'However' shows contrast, while 'therefore' shows result. (3) Sample: 'Public transport reduces traffic because it carries more people in less space. It also helps low-income residents reach work.'
