English Collocations: Why Familiar Words Do Not Always Fit Together
You are writing an email about a class you want to organise. You know the words do and decision, so you write: “We need to do a decision by Friday.”
The message is understandable. The verb tense and sentence structure may look familiar, yet the combination needs attention: in this sentence, make a decision is the usual expression.
English collocations are word combinations that are commonly used together. They help explain why knowing the meaning of each word does not always tell you how to combine those words in a sentence. Learning these combinations gives you more reliable ways to express an idea with vocabulary you already know.

What are English collocations?
A collocation is a combination of words that regularly occur together in a particular meaning or use. You meet them in ordinary conversations, emails, news reports and books.
They can take different forms:
Verb + noun: “We reached an agreement about the repairs.”
Adjective + noun: “Heavy rain delayed the match.”
Adverb + adjective: “The organiser was deeply concerned about the cost.”
The individual words may be familiar. What you are learning is the relationship between them.
Knowing agreement, for example, includes knowing that people can reach an agreement. That phrase gives you a way to describe the outcome of a discussion. You still choose the tense and add the details your message needs: “They reached an agreement yesterday” or “We hope to reach an agreement soon.”
A collocation gives you a useful pattern within which you can build your own sentence.
Why familiar words can be difficult to combine
A dictionary definition answers one question: what does this word mean? Writing or speaking introduces another: which words usually accompany it here?
Consider weather descriptions. English commonly uses heavy rain and strong winds. Both descriptions concern intensity, but the preferred adjective changes with the noun. A general understanding of heavy and strong does not automatically supply that information.
Translation can also leave a gap. A combination that works in your first language may use a different verb or adjective in English. Cambridge’s guidance on collocation errors highlights differences between languages and the difficulty of predicting these combinations from rules.
This is a useful reason to revisit familiar vocabulary. When you encounter an ordinary word in an unfamiliar combination, you have found something worth checking, even if you understood the sentence immediately.
A short message before and after editing
Imagine someone preparing a proposal for evening classes. Here is an illustrative first draft:
“Before we do a decision about the evening classes, we should make a survey of local residents. Their answers will help us choose a suitable day.”
The purpose is clear, but two verb choices need attention. A revised version reads:
“Before we make a decision about the evening classes, we should conduct a survey of local residents. Their answers will help us choose a suitable day.”
The changes are small. The writer keeps the same proposal, sequence and level of detail while choosing verbs that fit the nouns.
There are other acceptable choices. Do a survey and carry out a survey are also established combinations. Cambridge’s guide to using survey gives these alternatives alongside conduct a survey.
You do not need to replace every simple verb with a more formal one. For a short message to a colleague, “Let’s do a survey” may communicate exactly what you need.
How to check an English collocation
When a phrase seems uncertain, give yourself a specific question to investigate. In the example above, that question is: “Which verb can I use with survey when I mean asking people for information?”
A practical checking process has four parts:
Identify the intended meaning. A word can have several meanings. Make sure the dictionary entry matches what you want to say.
Read the examples around the key word. Look for the verb, adjective or other word that accompanies it. With survey, an example may give you conduct a survey.
Check the surrounding language. Notice articles, prepositions and any labels indicating formal, informal, British or American usage.
Write a sentence for your own situation. Preserve the useful combination while changing the details: “We will conduct a survey of evening students.”
A learner’s dictionary is a useful starting point; a collocations dictionary can offer a wider selection of combinations. If one entry does not answer your question, compare another reliable reference or several edited texts using the same meaning.
Avoid treating the first phrase you find online as a rule. Check what the phrase means in that particular sentence.
More than one combination can be correct
Learning collocations does not mean assigning one permanent partner to every word.
For example, Cambridge’s entry for decision includes both make a decision and reach a decision. Both are established expressions. Your choice depends on the sentence and what you want to emphasise.
The British Council’s overview of collocation also distinguishes combinations that allow relatively little substitution from those with more flexibility.
That distinction matters when you receive a correction. If someone changes your wording, ask whether the original was unsuitable, whether the revision fits the context better, or whether both versions are possible.
A useful correction explains the choice. It should help you decide what to write next time.
Record the expression with enough context
A vocabulary note that says only “survey = a way of collecting information” leaves out the verb you may need later.
A more useful note could contain:
Expression: conduct a survey of local residents
Purpose: collect information about their preferences
My example: “The library conducted a survey of local residents before changing its opening hours.”
You now have a combination, a meaning and a situation in which to use it. The example also shows how the verb changes in the past tense.
Keep the record selective. Choose expressions you are likely to need in your own work, study or everyday life. When you review them, try creating a different message with the same combination, then check it against your reference.
For make a decision, you might describe a choice about a course, a purchase or a travel plan. Changing the situation helps you check whether you can use the expression beyond the sentence in your notes.
Notice combinations while you read
When you understand a sentence easily, it is possible to overlook the way its words fit together.
During a second reading, pause over a few useful expressions. Which verb accompanies the noun? Is there an adjective you would not have chosen yourself? Would this combination help you describe something in your own life?
Our guide to improving vocabulary through reading explains how to select useful language and record it in context. Add attention to collocations by keeping the relevant words together in your notes.
You can then use one expression in a short message or spoken response. If you recognise it on the page but struggle to use it in conversation, our article on knowing grammar rules and using them when speaking explores that wider gap between understanding and use.
Choose support for the difficulty you have
For a particular word combination, consult a dictionary and examples of actual usage. If your uncertainty also involves recurring choices such as make and do, a focused explanation with practice can complement that checking.
For B2 learners, Mastering English Grammar B2 Through Confusions covers choices including make or do, with explanations, contrasting examples, practice and explained answers. Use it to investigate the distinction, then check combinations connected to what you want to communicate.
The next time a sentence feels uncertain, identify the words that need to work together. Check their combination, keep a useful example and try the expression in a message of your own.
