Collocation
Why is it heavy rain and not strong rain?
Collocation is the tendency of words to occur together more often than chance would predict, as in *make a decision* or *heavy rain*, so part of a word’s meaning lies in its usual partners.
A student writes I did a mistake in the test. Every word is right and the grammar is fine, yet it sounds wrong, because English speakers make mistakes, do homework and take photos. In 1957 J. R. Firth summed up the idea in a line corpus linguists still quote: “You shall know a word by the company it keeps!”
Collocation is the habitual co-occurrence of words, such as make a decision, heavy traffic or strong coffee. John Sinclair turned Firth’s insight into a method. Take a node word, gather every example from a corpus, and count which words, its collocates, appear a few words either side; a concordance lays these out line by line. Raw counts mislead, because the keeps company with everything, so researchers use association measures, statistics of how strongly two words attract each other. Mutual information (MI) asks how much more often a pair occurs than chance would predict, so it favours tight, rarer pairs like densely populated. The t-score asks how sure we can be that a pairing is no accident, so it favours frequent pairs like hard work.
Learner research shows why this matters. Nesselhauf (2003) found that the first language shaped advanced German-speaking learners’ verb–noun collocations much more than earlier, smaller studies had suggested. Durrant and Schmitt (2009) found that non-native writers rely heavily on frequent collocations but underuse less frequent, strongly associated ones. Collocation is also the everyday face of Sinclair’s idiom principle: fluent speakers choose words in partnerships, not one at a time.
In actionRight words, wrong company
- S
- Is strong rain wrong? The grammar is fine.
- T
- The grammar is fine. But English speakers usually say heavy rain.
- S
- But we say strong wind.
- T
- Yes. Strong wind, heavy rain. Each word has favourite partners. Let’s check a few more in the corpus.
Invented exchange. The problem is not meaning or grammar but company, which is exactly what corpus searches make visible.
In the classroom
- 1
Record vocabulary as partnerships, not single words: when decision comes up, note make, reach and tough with it, and recycle the whole chunks in later lessons.
- 2
Settle doubtful pairs with evidence: compare do a mistake and make a mistake in a free corpus tool such as SkELL, and let learners see the difference in frequency for themselves.
- 3
Present target collocations as intact wholes rather than relying only on verb–noun matching exercises, which Boers and colleagues (2014) found can leave learners remembering the wrong pairings.
Myth and reality
Collocations are colourful fixed expressions, like idioms, that only advanced learners need.
Most collocations are ordinary and transparent, like heavy traffic or take a break, and they run through everyday text. Learners who lack them sound unnatural even when their grammar is accurate.
Reflect
Which of your learners’ recent “correct but strange” sentences were really collocation problems, and did your feedback treat them as grammar, vocabulary or something else?
Worth a minute before your next lesson, or a conversation in the staffroom.

Firth introduced “meaning by collocation” in his 1951 paper “Modes of meaning”, reprinted in this collection. The “company it keeps” line comes from his 1957 “Synopsis of linguistic theory” (p. 11), published in a separate volume. Harold Palmer’s 1933 report on English collocations, written in Japan for teachers, had already used the term.
