IELTS grammar: Linking Words for Cohesion

Linking words sit at the centre of a common misunderstanding about the Coherence & Cohesion criterion, which many candidates treat as a checklist of "sophisticated" connector phrases to insert as often as possible, when it is actually assessing whether ideas connect logically and whether a reader can follow the argument without effort. The specific error pattern this misunderstanding produces is stacking multiple linking words into the same paragraph, often one at the start of nearly every sentence, which paradoxically makes an essay read as less coherent, not more, because heavy signposting draws attention to the seams between ideas rather than letting the ideas flow into each other.

Linking words fall into functional categories, and choosing the correct category for the actual logical relationship between two ideas matters far more than choosing an impressive-sounding word within the wrong category. Addition: "furthermore," "in addition," "moreover," "besides this." Contrast: "however," "on the other hand," "whereas," "nevertheless," "despite this." Cause and effect: "as a result," "consequently," "this means that," "therefore," "due to this." Example: "for instance," "for example," "a case in point is." Concession: "although," "even though," "while it is true that." Each category signals a distinct logical move, and using a contrast word to introduce what is actually an example, or a cause-effect word to introduce what is actually a simple addition, confuses the reader about the shape of the argument even when every individual sentence is grammatically correct.

The most common overuse error is opening consecutive sentences with linking words regardless of whether each one is actually needed: "Furthermore, this is an important issue. Moreover, it affects a large number of people. In addition, several solutions already exist." Every sentence here is grammatically fine in isolation, but the paragraph as a whole reads as mechanically signposted rather than genuinely connected, because "furthermore," "moreover," and "in addition" are all doing the same job (marking pure addition) three times in a row, which suggests the writer is padding a list of separate points rather than building a developing argument. A stronger version drops most of the explicit signposting and lets the content itself carry the connection: "This is a significant issue, affecting a large number of people, and several solutions already exist that could address it directly." One combined sentence, no linking words needed, arguably reads as more coherent than three short ones stitched together with connectors.

A second common error is choosing a linking word that doesn't match the actual logical relationship between the two ideas it joins. INCORRECT: "Remote work offers flexibility. However, employees often report higher job satisfaction." (There is no contrast here — higher satisfaction is a consequence or an additional benefit of flexibility, not something that opposes it.) CORRECT: "Remote work offers flexibility, and as a result, employees often report higher job satisfaction." Before inserting any linking word, it's worth explicitly checking: does the second idea genuinely contrast with the first, follow from it as a cause-and-effect result, add a separate but related point, or illustrate it with a specific example? Picking the category that actually matches the content, rather than picking whichever connector sounds most formal, is the entire skill here.
