What a collocation is
Words that habitually go together. Make a decision, not do a decision. Heavy rain, not strong rain. Take a photo, pay attention, reach a conclusion, strongly disagree.
There is rarely a rule. Do the washing up and make the bed are both housework, and swapping the verbs produces two sentences no English speaker has ever said. You cannot derive them; you can only know them.
Which is what makes them a good measure of language ability — and it is why every major rubric mentions them explicitly at the top of the vocabulary scale.
Why they make you fluent, not just accurate
This is the part that is rarely explained, and it is the reason collocations are worth more than any other vocabulary work.
A fluent speaker does not build make a decision out of make plus a plus decision. They retrieve it whole, as a single stored unit. The phrase costs them roughly what one word costs.
That is the whole argument. Collocations reduce the amount of sentence you have to construct in real time, which frees you to think about what you are saying rather than how to say it. They raise Lexical Resource because they are precise and natural, and they raise Fluency because they are cheap to retrieve.
Very little else in language study pays into two criteria at once.
Spoken collocations are not academic collocations
A common mistake: candidates learn collocations from an academic list — conduct research, pose a significant risk, a compelling body of evidence — and then use them in the speaking test, where they sound recited.
The collocations of spoken English are ordinary, verb-heavy, and mostly built from a small set of very common verbs. That is not a lesser vocabulary; it is the right one for the room.
| Function | Spoken collocations worth having |
|---|---|
| Opinion | I'd say, to be honest, the way I see it, it strikes me as |
| Hedging | it depends on, more or less, by and large, up to a point |
| Cause | it comes down to, it's mostly down to, that leads to, that's what causes |
| Degree | a huge difference, a slight improvement, nowhere near enough, far more likely |
| Time / habit | I tend to, I used to, every now and then, more and more |
| Contrast | having said that, then again, on the other hand, the trouble is |
| Experience | it made a real difference, it took some getting used to, I got the hang of it |
Notice how ordinary those are. It comes down to, having said that, I tend to — no rare words at all. And notice what they do to your grammar: I used to is a past habitual, having said that is a participle clause, it depends on whether introduces a conditional. The chunks carry complex grammar in with them, which is why they raise more than one score.
How to learn them so they arrive when you need them
The point of a collocation is retrieval under pressure. So the way you store it matters more than how many you store.
- Never learn a word alone. When you meet decision, learn make a decision. When you meet risk, learn pose a risk and take a risk — which mean different things. A word learned alone is a word you will use with the wrong verb.
- Learn them in a whole sentence you would actually say. Not make a decision on a flashcard, but I had to make a decision pretty quickly. You are training retrieval in context, and the context is what triggers it.
- Say them out loud, many times. This is motor memory, not knowledge. A chunk you have read is not a chunk you can produce — you need the phrase to come out as one movement.
- Collect from real speech, not from lists. When you hear a native speaker say something you would not have said, write down the whole phrase. That is a collocation you were missing, and it arrived with proof that people really say it.
- Force ten of them into your next practice answer, deliberately and awkwardly. They stop being awkward after about the third use.
For the test, and for real English
For the test: collocations are the highest-return vocabulary work available, because they raise Lexical Resource and Fluency together — one habit, two criteria. Learn spoken chunks for speaking and academic ones for writing, and do not mix the rooms.
For real English: this is what fluency is. Native speakers are not fast because they think faster; they are fast because most of what they say is retrieved rather than constructed. Every chunk you acquire is a small piece of sentence you will never have to build again, and they accumulate for the rest of your life.
It is also the difference between English that is correct and English that sounds like a person. Strong rain is comprehensible, grammatical, and marks you instantly as a learner. Heavy rain costs nothing more to say.
Frequently asked questions
Do collocations improve fluency or just vocabulary?
Both, and the fluency effect is the bigger one. A fluent speaker retrieves 'make a decision' as a single stored chunk rather than assembling it from parts, so the phrase costs about what one word costs. Everything you have to construct in real time is planning load, and planning load is what produces mid-phrase pauses — exactly what the fluency descriptors penalise. A speaker with a good stock of chunks pauses less, and pauses in better places, without speaking any faster.
What collocations should I learn for the speaking test?
Spoken ones, which are ordinary and verb-heavy rather than academic: 'it depends on', 'it comes down to', 'having said that', 'I tend to', 'more or less', 'nowhere near enough', 'it took some getting used to'. Academic collocations like 'conduct research' or 'pose a significant risk' belong in writing, and spoken aloud they sound recited, which examiners discount.
How do I learn collocations effectively?
Never learn a word alone — when you meet 'decision', learn 'make a decision'. Store them inside a whole sentence you would actually say, because you are training retrieval in context. Say them out loud repeatedly, since this is motor memory rather than knowledge. And collect them from real speech: when a native speaker says something you would not have said, write down the whole phrase.
Are collocations the same as memorised answers?
No, and the distinction matters because memorised answers are discounted. A collocation is a building block that attaches to anything you want to say; a script is a fixed answer to a question you hope you are asked. Ten collocations dropped into a memorised paragraph is still a memorised paragraph. Learn the blocks, but do not pre-assemble the wall.
Why do collocations matter if my grammar is already correct?
Because 'strong rain' is grammatical, comprehensible, and marks you instantly as a learner, while 'heavy rain' costs nothing more to say. Every major rubric names collocation explicitly at the top of the vocabulary scale, since word partnerships cannot be derived from rules — you can only know them, which makes them a good measure of real ability. They also carry grammar with them: 'I used to' is a past habitual and 'having said that' is a participle clause.
