Collocations That Lift Your IELTS Band Score

Two candidates can know exactly the same words, yet one sounds natural and the other sounds slightly "off". The difference is often collocation: the way certain words naturally go together. Learning IELTS collocations is one of the fastest ways to improve your Lexical Resource score, because examiners specifically look for awareness of collocation at the higher bands. This guide explains what collocations are, gives useful examples by topic and shows you how to practise them.

What is a collocation?

A collocation is a combination of words that native speakers use together frequently. There is often no logical rule; it is simply what sounds natural.

• We say make a decision, not do a decision.
• We say heavy traffic, not strong traffic.
• We say a strong argument, not a powerful argument (in most contexts).

Using the wrong partner word rarely makes your meaning unclear, but it signals a less natural command of English, which affects your score.

Common collocation patterns

Verb + noun

• raise awareness, pose a threat, meet a deadline, reach a conclusion, take responsibility

Adjective + noun

• a significant increase, a key factor, a growing concern, a widespread belief

Adverb + adjective

• highly effective, widely accepted, deeply concerned, increasingly common

Verb + adverb

• rise sharply, decline steadily, vary considerably, strongly recommend

Noun + noun

• traffic congestion, job satisfaction, public transport, climate change

Useful collocations by IELTS topic

Education

• acquire knowledge, attend lectures, tuition fees, vocational training, academic performance

Environment

• reduce carbon emissions, renewable energy, natural habitats, take urgent action, environmental damage

Work

• a demanding job, career prospects, a heavy workload, work-life balance, earn a living

Health

• a balanced diet, lead a sedentary lifestyle, take regular exercise, mental well-being, public health

Technology

• rapid technological advances, access information, social media platforms, heavily reliant on, online privacy

Worked example: fixing unnatural phrases

Original (Band 6 style):

Many people do a lot of stress in their work, and this makes big damage to their health. The government should make actions to solve this.

Improved (Band 7 style):

Many people experience high levels of stress at work, and this can cause serious damage to their health. The government should take action to address this issue.

The corrections:

• do a lot of stress → experience high levels of stress
• makes big damage → cause serious damage
• make actions → take action
• solve this → address this issue

The ideas have not changed at all, but the paragraph now reads naturally.

Collocations in Writing Task 1

Academic Task 1 relies heavily on verb + adverb and adjective + noun collocations for describing data: rose steadily, fell sharply, a slight decline, a dramatic increase, remained stable. Our guide to describing line graphs in Writing Task 1 has a full set.

Collocations in Speaking

Spoken collocations are often less formal: have a go, make friends, catch up with someone, take it easy, a quick bite to eat. Using these naturally helps you sound fluent and relaxed. Do not force them; one or two natural phrases per answer is plenty.

How to learn collocations effectively

1. Notice them: when reading or listening, highlight word partnerships, not just single words.
2. Record them in groups: organise by topic or by key word (for example, all collocations with decision).
3. Use a dictionary with examples: good learner dictionaries show typical collocations.
4. Recycle them: use new collocations in your own sentences within two days.
5. Test yourself: cover one half of the phrase and try to recall the partner word.

Our Daily Vocabulary feature is a convenient way to build this habit, and the IELTS vocabulary guide groups words by topic.

Common mistakes

• Direct translation from your first language: open the light instead of turn on the light.
• Mixing formal and informal collocations in the same essay.
• Overloading: packing every sentence with collocations until it sounds artificial.
• Learning lists without context: a phrase you cannot use in a sentence will not help in the test.

For a broader approach to building vocabulary, see our guide to vocabulary for Band 7. Grammar and collocation work together, too; complex sentences for IELTS shows how to combine good phrases into well-built sentences.
