Collocation
Collocation is the tendency of words to co-occur in natural language with a frequency greater than chance. Native speakers say "make a decision" not "do a decision," "heavy rain" not "strong rain," "deeply concerned" not "very concerned." These combinations are not governed by grammar rules — they are conventions of use, stored and retrieved as units.
The concept was first formalized by J.R. Firth (1957): "You shall know a word by the company it keeps." It became central to ELT through Michael Lewis's Lexical Approach (1993), which argued that fluent language use depends more on retrieving pre-fabricated chunks than on generating sentences from grammar rules.
Types of Collocation
Grammatical collocations — a content word + a grammatical word (preposition, infinitive):
- depend on, interested in, succeed in, responsible for
- a reason to, difficulty in, afraid of
Lexical collocations — content word + content word:
| Pattern | Examples |
|---|---|
| Adjective + noun | strong coffee, heavy traffic, bitter disappointment |
| Verb + noun | make progress, take action, pay attention, raise concerns |
| Adverb + adjective | highly unlikely, deeply moved, utterly ridiculous |
| Verb + adverb | decline sharply, strongly recommend, flatly refuse |
| Noun + noun | birth rate, side effect, power supply |
The Collocational Continuum
Collocations are not binary (fixed or free) — they sit on a continuum:
- Free combinations — any adjective can modify the noun (a red/blue/large/small car)
- Collocations — statistically preferred combinations (strong tea but not powerful tea)
- Fixed expressions / idioms — completely frozen (kick the bucket, by and large)
Most teaching attention should focus on the middle zone — collocations that are frequent enough to sound natural but not so fixed that they are simply memorized as idioms.
Why Collocations Matter
Naturalness — collocational errors rarely cause misunderstanding, but they mark a speaker as non-native. "Do a mistake" is intelligible but immediately signals a learner. Building collocational knowledge is one of the most efficient routes to sounding natural.
Processing speed — collocations stored as chunks are retrieved faster than language assembled word by word. This is why collocational knowledge correlates strongly with fluency (Boers et al. 2006).
Receptive depth — knowing a word's collocational profile means knowing it deeply. A learner who knows "make" only as "create/produce" will be confused by make a decision, make progress, make an effort, make a mistake. Collocational knowledge is vocabulary depth.
Teaching Collocations
- Notice and record — train learners to notice collocations when reading/listening and record them as chunks, not isolated words. A vocabulary notebook entry for "decision" should include make a decision, reach a decision, tough decision, final decision
- Corpus tools — use concordance lines from corpora (COCA, BNC, SkELL) to show learners which words naturally co-occur
- Collocation matching — give learners two columns (verbs + nouns, adjectives + nouns) and ask them to match natural combinations
- Error correction — when learners produce unnatural combinations (do a travel, big rain), reformulate with the natural collocation and draw attention to it
- Deliberate learning — at higher levels, teach collocational profiles of high-frequency words systematically, especially verb-noun and adjective-noun patterns
Collocation is the connective tissue of natural language. It links to Lexical Sets (but is a more productive organizing principle for vocabulary teaching), to MFP (collocational information is part of form analysis), and to The Lexical Approach (which places collocations at the centre of language learning).
