## Start with the relationship between ideas

Cohesion is how the language connects parts of a response; coherence concerns whether the message follows a sensible path. The public Writing descriptors assess organisation and connections together. For preparation, distinguish the two: first decide what the paragraph means, then choose language that makes its sequence easy to follow.

Consider this original sequence: “The library closes early. Therefore, students need transport. Moreover, books are expensive.” Each sentence could be grammatical, yet the relationships are unexplained. Does early closure force a journey to another library? Are expensive books the reason students need the library? The reader should not have to invent those missing links.

A clearer plan might be: early closing limits evening access; buying the same materials is costly; extending opening hours gives students a practical alternative. That plan supplies a causal chain. You can then write it without putting a connector at the beginning of every sentence. Clear content gives the cohesive language something useful to connect.

Use the [Task 2 guide](/ielts/writing/task-2) for the whole essay. This page focuses on sentence connections within and between paragraphs. The teaching examples are original and illustrate revisions rather than carry an official band score. The same clarity check helps an Academic report and a General Training letter, although their purposes differ.

## Give every pronoun one recoverable meaning

Original sentence: “The council told the residents that they should change its policy.” Who should change the policy, and whose policy is it? The sentence contains multiple possible groups and an unclear possessive. A useful revision is: “The residents asked the council to change its parking policy.” The revision clarifies both the actor and the object.

Pronouns such as it, they and this save repetition only when the reader can recover their meaning. After two plural nouns, they may point to either. After a whole paragraph, this may point to one action, an argument or the entire situation. Add a defining noun when needed: this restriction, this funding proposal or these evening classes.

Original pair: “Students can borrow tablets from the library. This is useful.” Better pair: “Students can borrow tablets from the library. This loan scheme gives pupils without suitable devices a way to complete digital assignments.” The second version identifies the reference and explains the benefit instead of labelling the first sentence useful.

Do not replace every repeated noun. Repeating a precise term can be clearer than introducing a vague substitute. If a report compares bus passengers and train passengers, a later reference to travellers may wrongly include people travelling by other modes. Keep the noun when substitution would broaden or blur the category.

Check number agreement as well as meaning. A singular service needs it; plural services need they. If you change the noun during revision, inspect later references again. Grammar and reference can drift when a sentence is removed or moved. Read at least the surrounding pair of sentences after each substantial edit.

## Reduce repetition without changing the claim

Substitution replaces material the reader already understands. In an original comparison, “The morning class is larger than the evening one” uses one for class. That works because both items are clearly classes. In “The morning class is larger than the evening programme”, the nouns may describe different units, so the comparison needs clarification rather than a synonym.

A useful general reference can summarise a specific action. “The college extended opening hours and introduced weekend access. These changes allow more students to use the workshop.” Here changes refers to the two preceding actions. If the previous paragraph also discussed staff recruitment, the reference could become unclear; specify the access changes if necessary.

The [British Council coherence and cohesion tips](https://takeielts.britishcouncil.org/prepare/ielts-academic/writing/tips-coherence-cohesion) help connect planning and development. Use a paragraph's central claim as the boundary for substitution. Moving from some commuters to everyone changes the scope, even if both expressions avoid repeating the same words. Variety should not quietly enlarge the argument.

In an Academic report, preserve categories and time periods. “The figure for buses” can replace “the percentage of journeys made by bus” after the measure is established. It should not replace passenger numbers when the chart only gives percentages. The [numerical comparison guide](/articles/ielts-task-1-percentages-comparisons) works through that distinction.

## Choose a connector after identifying its function

Before writing however, ask what contrasts. Before writing therefore, ask what conclusion follows. Before writing for example, identify the general claim the example demonstrates. A connector signals a relationship; it does not create one. If you cannot explain that relationship without the connector, strengthen the reasoning first.

Original pair: “Public transport is cheaper than taxis. However, it can reduce commuting costs.” The second sentence supports the first, so however misleads. A repair is: “Public transport is often cheaper than taxis, which can reduce commuting costs for regular travellers.” The qualification often also avoids making a universal fare claim.

Original pair: “The school bought new computers. Therefore, every pupil achieved better results.” The conclusion exceeds the evidence. A more careful version is: “The school bought new computers, giving pupils more opportunities to practise digital tasks. Whether this improves examination results also depends on teaching and how the equipment is used.” This repairs the causal claim, not just the transition.

Punctuation matters when joining independent clauses. “The centre is accessible, however it closes early” needs repair. Write “The centre is accessible; however, it closes early” or use two sentences. Do not make every connection with a semicolon; choose sentence forms you can control accurately under the test clock.

Avoid a connector quota. A paragraph with five visible linking phrases can still be confusing, and a paragraph with fewer can flow clearly through repeated subjects and precise references. Assess the relationship and readability, not the count. The descriptors explicitly allow assessment of inappropriate or excessive cohesive-device use.

## Repair a paragraph in three passes

Original weak paragraph: “Online courses help workers. They give them flexibility. Moreover, they are convenient. However, travel is reduced. This is good because they can learn. Therefore, all colleges should move online.” The references are crowded, the contrast is unsupported, and the final policy is broader than the paragraph's evidence.

First pass, reasoning: identify one benefit and its mechanism. Workers can study around variable shifts because some courses offer recorded sessions. Removing a campus journey may also free time, but this does not prove that every course should be online. Practical subjects and access limitations need consideration before such a broad conclusion.

Second pass, references: identify courses, workers and sessions explicitly where ambiguity would arise. Revised original paragraph: “Recorded online courses can help workers whose shifts prevent them from attending a fixed evening class. These learners can review a lesson after work rather than miss it entirely. Studying at home also removes the journey to campus. This flexibility can make participation more practical, provided learners have suitable internet access and the course does not require regular use of specialist facilities.”

Third pass, connectors: the paragraph uses also to add a related benefit and provided to introduce conditions. It does not need moreover, furthermore and in addition together. Read the revised paragraph aloud and note whether each sentence has a distinct job. Keep an explanation, example or qualification only when it advances the point.

Use the [original example guide](/articles/ielts-task-2-original-examples) to develop the mechanism further if the essay needs it. This paragraph is a teaching illustration, not a complete answer to an unspecified question. Its quality in a real essay depends on whether it addresses that essay's exact prompt and position.

## Use a focused editing check under time pressure

__Original cohesion repairs__
| Problem               | Repair                            | Reason                                  |
| --------------------- | --------------------------------- | --------------------------------------- |
| Ambiguous they        | Name the residents or the council | Identifies the actor                    |
| Vague this            | Write this loan scheme            | Names the preceding idea                |
| Unsupported therefore | Explain the mechanism and limits  | Avoids a conclusion beyond the evidence |
| Misleading however    | Use a supporting connection       | Matches the actual relationship         |
| Overbroad substitute  | Keep the precise category         | Preserves the claim’s scope             |

In untimed practice, underline each pronoun and draw an arrow to the noun or idea it represents. Circle each connector and label its job: contrast, result, addition, example or condition. If an arrow has two possible destinations or a label does not fit, revise the sentence. The table gives concrete repairs to practise.

Then remove one connector at a time. If the relationship remains obvious, consider whether the word is necessary. If the relationship disappears, check whether you have relied on a label instead of explaining the connection. This drill is a teaching method, not an official marking procedure or a formula for a particular score.

For timed work, keep the check shorter: vague this, ambiguous they, unsupported therefore, repeated moreover. Review these after checking task coverage and the minimum length. There is little value in polished referencing if the essay has ignored half the question or the letter has omitted a required point.

[topin's free IELTS Academic mock](/ielts/practice-test), marked on the official scale, lets you test whether clear references survive the Writing clock. General Training candidates should also practise original letters using the official General Training specification. Save one before-and-after paragraph from each review and explain why each change improves the meaning.

## FAQs

Do more linking words mean a higher Writing score?

No. Connections must be accurate and appropriate. Excessive or mechanical use can weaken the response.

Is it wrong to repeat a noun?

No. Repeat a precise noun when a substitute would make the reference or category unclear.

How can I repair an unclear “this”?

Add a defining noun such as this restriction or this loan scheme, then check that it accurately summarises the preceding idea.

Does this apply to General Training letters?

Yes. References and logical connections need to be clear in letters too, while the tone and required content must fit the situation.

Can I memorise a connector list?

A list can help you study meanings, but choose a connector from the actual relationship between ideas rather than inserting it to meet a quota.
