What does collocation mean?
Collocation refers to the way certain words habitually appear together in a language, forming partnerships so familiar that they feel inevitable: we say 'heavy rain' rather than 'strong rain', and 'make a decision' rather than 'do a decision'. In linguistics, a collocation is a combination of words that occurs far more frequently than random chance would predict, reflecting the conventional patterns every fluent speaker absorbs unconsciously. The term also carries an older, broader sense: the act of placing things side by side, as in the juxtaposition of ideas or objects. Knowledge of collocations is central to vocabulary teaching, since learners who know individual words may still produce sentences that sound unnatural if their word pairings violate convention. Writers and translators rely on collocational awareness to achieve phrasing that seems effortless and idiomatic.
nounA habitual combination of words that occur together more frequently than chance would suggest, such as 'heavy rain' or 'make a decision'. More broadly, the act or fact of placing things side by side, especially in a way that creates a meaningful relationship.
- Linguistics: a pair or group of words that are habitually used together, such as 'heavy rain' or 'fast asleep'.

The regular English plural, formed by adding -s; standard in all varieties.
"The textbook lists fifty essential collocations for advanced learners."
'Strong tea' sounds fine but 'powerful tea' sounds wrong — that invisible grammar of habit is what linguists call collocation, and native speakers obey it without ever being taught.

Etymology of collocation
The word derives from Latin roots: 'com-' (together) combined with 'locare' (to place), via the past participle 'locatus'. It entered English in the early modern period, first appearing in the seventeenth century in the literal sense of placing things together. Its specialized linguistic sense, referring to habitual word pairings, was popularized in the twentieth century by linguists such as J.R. Firth, who famously observed that 'you shall know a word by the company it keeps'. It shares its Latin root with words like 'colleague', 'collect', and 'collate'.
