This article is part of our Complete English Grammar Practice Guide — explore all grammar and vocabulary topics with interactive exercises.
You can have perfect grammar and still write an essay that sounds unnatural — because individual words alone are not enough. Native speakers and academic writers rely on collocations: word partnerships that habitually go together. Getting these right is one of the fastest ways to make your writing sound more academic and to raise your IELTS band score.
This guide explains what collocations are, then gives you the highest-value academic collocations grouped by function — research verbs, argument verbs, adjective and noun pairings, hedging language, and the errors to avoid. Build these into your active vocabulary and your essays will instantly sound more fluent.
Key Takeaways
- A collocation is a pair or group of words that naturally combine, such as conduct research or a significant difference.
- Academic collocations make essays sound precise and formal — vague words like big become significant or considerable.
- IELTS Writing Task 2 rewards collocations directly through the Lexical Resource criterion.
- Learn collocations as fixed chunks, not single words: note draw a conclusion, not just conclusion.
- Avoid translation errors such as make research — the correct forms are do, conduct, or carry out research.
What Are Collocations?
A collocation is a combination of words that English speakers habitually use together. There is no grammatical rule that forces these combinations — they are simply the pairings that sound natural to fluent users. We say make a decision, not do a decision; we say heavy rain, not strong rain; and in academic English we say a significant difference rather than a big difference.
Collocations matter because language is stored and produced in chunks, not single words. When you learn a noun like conclusion, you also need to learn the verbs that go with it: you draw or reach a conclusion. Mastering these partnerships is what separates writing that is merely correct from writing that sounds genuinely fluent and academic.
In IELTS Writing Task 2, one quarter of your score comes from Lexical Resource, which explicitly rewards the accurate use of less common collocations. The same is true of university essays, where natural word pairings signal academic maturity.
Research Verb Collocations
When describing studies, data, and methods, certain verb–noun pairings appear again and again in academic texts. These are essential for essays that discuss evidence or research.
| Collocation | Example |
|---|---|
| conduct / carry out research | The team carried out research over three years. |
| gather / collect data | Surveys were used to collect data from participants. |
| analyse / interpret data | Statisticians analysed the data using software. |
| present / report findings | The article presents its findings in three sections. |
| obtain results | The experiment obtained surprising results. |
| review the literature | The author reviews the literature on climate policy. |
Notice how these allow you to write a full sentence chain naturally: “The researchers conducted a study, collected data from 500 participants, and analysed the results before presenting their findings.”
Argument Verb Collocations
Essays are built on argument, so the verbs you use to introduce claims, evidence, and conclusions are central to a strong academic style. These collocations help you structure a clear line of reasoning.
| Collocation | Example |
|---|---|
| draw / reach a conclusion | From this evidence we can draw a conclusion. |
| make / put forward an argument | Critics put forward a strong argument against the policy. |
| present / provide evidence | The study provides evidence for this view. |
| raise an issue / question | This raises an important question about ethics. |
| address a problem | Governments must address this problem directly. |
| support / challenge a claim | The data supports the claim that costs are rising. |
This essay puts forward the argument that remote work improves productivity and provides evidence to support this view.
Having weighed both sides, we can reach a balanced conclusion.
Adjective + Noun Collocations
This group transforms vague, everyday writing into precise academic prose. Instead of writing that something is big or important, choose the academic partner that fits.
| Collocation | Meaning / Use |
|---|---|
| a significant difference | a difference large enough to matter |
| a considerable impact | a large effect on something |
| a key / crucial factor | a very important cause or element |
| a crucial role | an essential part something plays |
| a growing concern | a worry that is increasing over time |
| a widespread belief | an opinion held by many people |
| a valuable insight | a useful understanding of something |
Replace weak everyday adjectives with their academic partners: big difference → significant difference; big effect → considerable impact; main reason → key factor. This single habit noticeably raises the tone of an essay.
Verb + Noun Collocations
These flexible verb–noun pairings express common academic ideas concisely. They appear across almost every essay topic, from technology to the environment.
| Collocation | Example |
|---|---|
| play a role | Education plays a vital role in development. |
| meet a need | The service meets a growing need for support. |
| pose a threat | Pollution poses a serious threat to health. |
| have an effect / impact on | Diet has a major impact on wellbeing. |
| gain / provide an insight | The interviews provide an insight into behaviour. |
| raise awareness | Campaigns raise awareness of the issue. |
Hedging Collocations
Academic writing values caution. Rather than making absolute claims, skilled writers hedge — they soften statements so they are easier to defend. Hedging collocations are some of the most useful phrases you can memorise for essays and IELTS.
Too strong (avoid)
- Technology has definitely improved education.
- Everyone believes that exercise is good.
- This proves the theory is true.
Hedged (academic)
- It could be argued that technology has improved education.
- It is widely accepted that exercise is beneficial.
- This suggests that the theory may be correct.
Other high-value hedging phrases include it is generally believed that, this may indicate that, there is a tendency for, and to a certain extent. They show examiners that you can write with academic balance rather than overstating your case.
Common Collocation Errors
Most collocation mistakes come from translating word-for-word from a first language. Learning the correct chunk prevents them.
make research → say: do / conduct / carry out research
make an experiment → say: do / carry out an experiment
say an opinion → say: give / express an opinion
do a mistake → say: make a mistake
high importance → say: great importance
get a conclusion → say: draw / reach a conclusion
Before an exam, prepare a short list of topic collocations for common themes (education, environment, technology, health). Knowing five strong collocations per topic gives you ready-made academic phrasing under time pressure.

Frequently Asked Questions
Collocations are words that naturally go together because native speakers habitually combine them. For example, we say make a decision rather than do a decision, and a significant difference rather than a big difference in academic writing. Collocations are not governed by strict grammar rules; they are simply the combinations that sound natural to fluent speakers. Learning them as fixed chunks helps you write more accurately and fluently.
Collocations are important because IELTS and academic essays are partly assessed on the range and accuracy of your vocabulary. Using natural academic collocations such as conduct research, draw a conclusion, and play a crucial role signals advanced lexical resource. In IELTS Writing Task 2, the Lexical Resource criterion explicitly rewards the accurate use of less common collocations, so they can directly raise your band score.
The correct collocations are do research, conduct research, or carry out research. Make research is a common error and is incorrect in English. In formal academic writing, conduct research and carry out research sound more precise than do research, though all three involving do, conduct, or carry out are acceptable. Never use make with research.
Strong research collocations include: conduct research, carry out research, gather data, collect data, analyse data, interpret data, present findings, obtain results, and review the literature. These verb-noun pairings appear constantly in academic articles and reports, so using them makes your writing sound authentic. For example: “The researchers conducted a study and collected data from 500 participants before analysing the results.”
Useful argument collocations include: make an argument, put forward an argument, present evidence, provide evidence, draw a conclusion, reach a conclusion, raise an issue, raise a question, and address a problem. For example: “This essay puts forward the argument that... and provides evidence to support this view, before reaching a balanced conclusion.” These verbs help structure a clear, academic line of reasoning.
High-value adjective-noun collocations include: a significant difference, a considerable impact, a key factor, a crucial role, a growing concern, a widespread belief, and a valuable insight. These replace vague everyday words with precise academic ones — for instance, a significant difference instead of a big difference, or a growing concern instead of a problem that is getting bigger. They add precision and formality to essays.
Hedging is cautious language that avoids overly strong claims, which is highly valued in academic writing. Common hedging collocations include: it could be argued that, it is widely accepted that, it is generally believed that, this suggests that, and this may indicate that. For example, “It could be argued that technology has improved education” is more academic and defensible than “Technology has definitely improved education.”
In IELTS Writing Task 2, one quarter of your score comes from Lexical Resource, which rewards a wide range of accurate vocabulary including collocations. Using natural collocations such as pose a threat, have a positive effect on, and play a vital role demonstrates that you can use ‘less common lexical items’, a key descriptor for Band 7 and above. Memorising and accurately deploying topic collocations is one of the fastest ways to raise this score.
Frequently used verb-noun collocations include: play a role, meet a need, pose a threat, have an effect on, have an impact on, gain an insight, provide an insight, raise awareness, and address an issue. For example: “Renewable energy can meet a growing need for power while posing fewer threats to the environment.” These collocations make abstract academic ideas sound natural and concise.
Common errors include make research (should be do or conduct research), make an experiment (should be do or carry out an experiment), say an opinion (should be give or express an opinion), do a mistake (should be make a mistake), and high importance (should be great importance). These mistakes usually come from translating word-for-word from a first language, so learning collocations as fixed chunks prevents them.
