A collocation is a pair or group of words that occur together more frequently than random association would predict — and whose combination feels natural to native speakers, even when alternatives are grammatically correct. Collocations are central to lexical competence: knowing a word fully means knowing what other words it typically appears with. See also Collocations.

What Makes a Collocation

Collocation is about statistical co-occurrence in real language, not just grammatical compatibility. Consider:

• ✓ make a decision (strong collocation)
• ✗ do a decision (grammatically possible, but non-collocating)

• ✓ strong tea (collocates)
• ✗ powerful tea (grammatically fine, but non-collocating)

• ✓ commit a crime (fixed collocation)
• ✗ perform a crime (unusual)

These preferences are largely arbitrary and must be learned — they are not predictable from word meaning alone.

Types of Collocations

Collocations range from strong (nearly fixed) to weak:

• Lexical collocations: noun + verb (make a mistake), adjective + noun (heavy rain), verb + adverb (deeply concerned)
• Grammatical collocations: word + specific preposition (interested in, depend on, result from)

Collocational strength can be measured using corpus tools with statistics like MI score or log-likelihood.

Why Learners Struggle with Collocations

Learners often know individual words but produce grammatically correct, non-native-sounding combinations — selecting plausible but un-collocating words based on first-language transfer or overgeneralization. This collocational failure is one of the chief markers distinguishing advanced learners from native speakers even at high proficiency levels.

Collocation and the Lexical Approach

Michael Lewis’s Lexical Approach (1993) placed collocation at the centre of language learning, arguing that language is primarily lexical rather than grammatical — that we should teach language in chunks rather than teaching rules and plugging in words. This has influenced how vocabulary and materials design are approached.

Practical Implications

• Dictionary entries should include collocational information
• Vocabulary lists should pair target words with their common collocates
• Learners benefit from large amounts of authentic input to absorb collocational patterns
• Corpus-informed learner dictionaries (Macmillan, OALD) and tools like SkELL or COCA help identify collocations
