Read this paragraph from a practice essay and tell me what feels wrong:

Firstly, grammar is the foundation of good writing. Moreover, vocabulary plays an equally important role. In addition, regular practice helps students improve. However, many learners study inefficiently. Therefore, a clear study plan is necessary. Furthermore, motivation matters too. In conclusion, success requires consistent effort.

Nothing in that paragraph is grammatically wrong, yet it is exhausting to read. Every sentence opens with a connector. The connectors do no real work — Moreover announces an added point, but the point has nothing to do with the sentence before it. By the final line, you have stopped trusting the words, because they keep signalling relationships that simply are not there.

When we mark practice essays together, this is the mistake I see most often: candidates have heard that linking words raise scores, so they push as many as possible onto the page. So here is the idea I want you to carry through this entire guide: linking words do not create logic — they reveal it. The connection between two ideas must already exist in your thinking; the connector's only job is to make that connection visible to your reader. Once that clicks, a small set of well-chosen words will do far more for your writing than a memorised list of fifty.

What Coherence and Cohesion Actually Mean

Linking words — sometimes called connectors or discourse markers — are signposts. They tell your reader how each sentence relates to the one before it: are we adding a point, contrasting with one, explaining a cause, or zooming in on an example?

They matter because Coherence and Cohesion is one of the four official criteria used to score IELTS writing, alongside Task Achievement in Task 1 (Task Response in Task 2), Lexical Resource, and Grammatical Range and Accuracy. And notice what the official descriptors actually reward: a Band 6 response is one where cohesion may be "faulty or mechanical", while a Band 7 response shows "clear progression throughout" and uses "a range of cohesive devices appropriately". The difference between those two bands is not the number of connectors — it is whether each one marks a genuine relationship.

Compare two versions of the same argument:

Version A: "Education is important. It helps people get jobs. Some people cannot afford it. The government should provide free education."

Version B: "Education is important because it helps people secure employment. However, some people cannot afford it. Therefore, the government should provide free education."

Version B contains no difficult vocabulary and no complex grammar. It simply uses three connectors (because, however, therefore) to expose the logic that Version A leaves hidden. The argument becomes easier to follow, and the tone becomes more academic — which is exactly what the examiner is trained to reward.

The rest of this guide walks you through twenty connectors, organised into the five jobs they do. For each one, you get a plain-English definition, a natural example, and one practical tip drawn from the errors I correct most often.

Job 1: Addition — Building on Your Ideas

Use these when your next point supports the same argument. Think of them as saying, "and here is one more reason."

1. Furthermore

Definition: Adds a stronger or more important supporting point to what you have just said.

Example: Regular exercise improves physical health. Furthermore, it has been shown to reduce symptoms of anxiety and depression.

Pattern: Furthermore, + full clause. Keep the comma after it.

2. Moreover

Definition: Very similar to furthermore, but often used to add a point that strengthens the argument even further.

Example: The new policy will reduce traffic congestion. Moreover, it will lower carbon emissions across the city centre.

Common mistake: Learners sometimes reach for moreover when they mean however. Remember: moreover adds; however contrasts. Mixing them up changes your meaning completely.

3. In addition

Definition: Introduces an extra piece of information or another supporting point.

Example: Learning a second language improves cognitive flexibility. In addition, it opens up career opportunities in a globalised economy.

Pattern: "In addition, + clause" starts a sentence cleanly, as in "The course covers grammar. In addition, it builds speaking confidence." You can also attach it mid-sentence: "The course covers grammar and, in addition, builds speaking confidence."

4. Not only ... but also

Definition: Links two parallel ideas and emphasises that both are true.

Example: Social media not only connects people across distances but also creates new opportunities for small businesses.

Advanced structure: When not only starts a sentence, the subject and verb swap places: "Not only did the scheme reduce traffic, but it also improved air quality." Used correctly once in an essay, this inversion makes a strong impression.

Job 2: Contrast — Showing the Other Side

These connectors let you present a counterargument or a surprising contrast. They are essential in Task 2 discussion essays, where you must deal with more than one viewpoint.

5. However

Definition: The workhorse of contrast. It signals that the next idea opposes or qualifies the previous one.

Example: Many people believe that a university degree guarantees a successful career. However, there are plenty of entrepreneurs who built their businesses without one.

Two positions: At the start of a sentence, follow it with a comma: "However, the evidence suggests otherwise." Between two clauses, use a semicolon before it and a comma after it: "The scheme was popular; however, it was expensive."

6. Nevertheless

Definition: Similar to however, but slightly stronger — it signals that what follows is surprising or goes against expectation.

Example: The initial cost of solar panels is high. Nevertheless, the long-term savings make them a worthwhile investment.

Tip: Reaching for nevertheless where another writer would automatically write however shows the examiner a wider range — which supports your Lexical Resource score.

7. On the other hand

Definition: Presents an alternative perspective, usually balanced against one already given.

Example: On the one hand, space exploration consumes enormous resources. On the other hand, the technologies developed for space programmes now benefit everyday life.

Common mistake: This phrase works best as a pair with on the one hand. If you are introducing only one contrasting point, however or nevertheless is usually the better choice.

8. In contrast

Definition: Highlights a sharp difference between two things being compared.

Example: Rural communities often have limited access to healthcare. In contrast, city residents can usually choose between several hospitals and clinics.

Pattern: "In contrast, + clause", or "In contrast to rural areas, cities offer..." — note that in contrast to attaches to a noun phrase, not a full clause.

9. Conversely

Definition: Signals a direct reversal: if the first statement is true, the opposite tends to be true as well.

Example: Countries with strict environmental laws tend to have cleaner air. Conversely, countries with weak regulations often struggle with pollution.

Tip: Conversely is formal and precise. It suits essays about cause-and-effect relationships between groups, systems, or countries.

Job 3: Cause and Effect — Explaining Why

Argument lives on cause and effect. These connectors show that one thing leads to another — the backbone of most Task 2 essays.

10. Therefore

Definition: Introduces a conclusion that follows logically from the previous statement.

Example: Childhood obesity rates have risen sharply in recent decades. Therefore, schools should prioritise nutrition education alongside physical activity.

Pattern: Sentence-initial Therefore, with a comma is the safest, clearest form.

11. Consequently

Definition: Like therefore, but emphasises that the result is a direct consequence of the cause.

Example: Air pollution exceeded safe limits for three months running. Consequently, the government issued a public health warning.

Tip: Consequently carries a slightly more formal register than therefore, which makes it a natural fit for academic essays.

12. As a result

Definition: A clear, direct way to show that one thing happened because of another.

Example: Many small businesses closed during the recession. As a result, unemployment in the region rose sharply.

Related form: "As a result of + noun phrase": "As a result of the factory closures, hundreds of families left the area." Note the difference: as a result introduces a clause; as a result of introduces a noun phrase.

13. Due to

Definition: Explains the cause of something. It is followed by a noun phrase, never a full clause.

Example: Due to rapid urbanisation, many cities are struggling to provide adequate housing.

Common mistake: "Due to the city is growing" is incorrect. Say "Due to the city's rapid growth" or "because the city is growing rapidly". If a full clause follows, you need because or since, not due to.

14. Hence

Definition: A compact, formal alternative to therefore, common in academic prose.

Example: Wind and solar farms generate electricity without burning fossil fuels. Hence, they sit at the centre of most national climate strategies.

Advanced structure: Hence can introduce a noun phrase without any verb: "Hence the government's growing interest in offshore wind." This fragment style is elegant when handled confidently — but if you are unsure, a full clause with therefore is safer.

Job 4: Example and Illustration — Making It Concrete

Abstract claims convince nobody until you ground them. These connectors introduce the evidence.

15. For instance

Definition: Introduces a specific case that illustrates a general statement. Interchangeable with for example in almost every context.

Example: Many cities have made their centres friendlier for pedestrians. For instance, several European capitals close main streets to cars on certain Sundays.

Pattern: "For instance, + comma + the example."

16. For example

Definition: The most common way to introduce an illustration. Clear, simple, always appropriate.

Example: Technology has transformed education. For example, students can now attend online lectures from universities on the other side of the world.

Tip: For example and for instance mean the same thing. Alternating between them gives you variety without repetition.

17. To illustrate

Definition: A slightly more formal way to introduce an example, often signalling that the example will be developed in detail.

Example: Investment in transport infrastructure can lift a whole economy. To illustrate, when a city builds a new metro line, goods and workers move faster, neighbourhoods near the stations attract new businesses, and jobs appear along the route.

Tip: Choose to illustrate when your example runs to two or three clauses. It prepares the reader for a longer development than for example would.

Job 5: Summary and Conclusion — Closing the Essay

Your final paragraph needs its own signals. These three do that job.

18. In conclusion

Definition: The standard signal that you are drawing your argument to a close.

Example: In conclusion, while technology brings clear benefits, its effects on mental health deserve far more attention from policymakers.

Tip: Some teachers discourage in conclusion because it is everywhere. The official descriptors do not penalise it. What matters is that the conclusion actually summarises your position rather than repeating the introduction word for word.

19. Overall

Definition: Summarises the main trend or message. In Task 1, this is the classic opener for your overview — the most important part of your whole report.

Example: Overall, visitor numbers increased across every age group over the decade shown.

Warning: Overall belongs in your Task 1 overview, but in conclusion does not. Task 1 reports describe data; they do not argue, so they have no concluding paragraph.

20. To sum up

Definition: A direct way to introduce a brief recap of your main points.

Example: To sum up, investing in early childhood education benefits individuals and society alike.

Tip: Marginally less formal than in conclusion. It suits a short, punchy closing sentence rather than a long final evaluation.

Five Habits That Quietly Cost Marks

Knowing the words is only half the job. When we review essays together, these five habits come up again and again:

1. Overloading every paragraph. If each sentence opens with a connector, the writing feels mechanical — remember that Band 6 warning about cohesion becoming "mechanical". Aim for roughly one connector every two or three sentences, and let other ideas flow without them.

2. Choosing a connector that contradicts your logic. Writing therefore when the relationship is really a contrast breaks your argument. Before you commit, ask yourself one question: am I adding, contrasting, showing a cause, or giving an example?

3. Dropping conversational connectors into academic prose. Plus, so, and besides feel chatty in an essay; prefer in addition, consequently, and furthermore. (Also is fine — just place it carefully, as in "The policy also reduced costs", rather than starting every sentence with it.)

4. Starting every sentence the same way. Vary the position of your connectors: "The scheme was popular; however, it was expensive" reads differently from "However, the scheme was expensive." That variety itself demonstrates grammatical control.

5. Forgetting the punctuation. Most sentence-initial connectors take a comma (However, ... / Therefore, ...), and a mid-sentence however needs a semicolon before it and a comma after it. Small slips like these accumulate under Grammatical Range and Accuracy.

Ten Minutes a Day: How to Build the Habit

Preparing for IELTS alongside work, family, or study is genuinely hard, so let us keep the practice plan realistic:

One connector a day. Pick a single word from the table each morning and write three sentences with it — on your commute, at lunch, before bed. Over a week, that is seven connectors practised in twenty-one sentences, which beats a three-hour cram on Sunday.

Read like a writer. Take any serious English-language news article and underline every linking word you find. For each one, ask why the writer chose that word at that moment. After a couple of weeks, your instincts start doing this automatically.

Run the upgrade pass. Take an old essay and find every bare and, but, and so. Replace only the ones sitting on top of a real relationship: a genuine addition becomes in addition, a real turn becomes however. Do not touch the rest — not every and needs upgrading, and forcing it creates the mechanical feel we started with.

Explain your choices out loud. Record sixty seconds on your phone explaining why nevertheless fits a sentence better than but. If you can justify a choice in speech, you truly own it — and articulating logic aloud feeds straight into the Speaking test.

Your Next Three Essays

You now have twenty connectors and, more importantly, a principle: reveal logic, do not decorate with it. Here is how to turn that into progress over your next three practice essays.

Essay one: choose three connectors — say because, however, and for example — and use each deliberately at least once. Nothing else. The goal is conscious control, not quantity.

Essay two: add one cause-effect connector and one summary connector. Afterwards, underline every linking word in the essay and check each one against the question: does it mark a relationship that genuinely exists?

Essay three: try the reverse exercise. Draft the essay with no connectors at all, read it, and only then insert the best ones. This forces the logic to stand on its own first — and clear progression through genuinely connected ideas is exactly what the higher-band descriptors reward.

Progress here is quiet but cumulative. One honest connector in the right place teaches you more than fifty scattered across your notes, and every essay you check against these criteria sharpens the instinct further. Keep going — your next draft is the best place to start.
