Fixed Expressions
Fixed expressions are multi-word sequences that permit no or virtually no variation in their form. They are stored and retrieved as unanalysed wholes rather than generated from grammatical rules. They sit at the most frozen end of the Formulaic Language continuum.
Characteristics
- Non-substitutable — Individual words cannot be swapped: by the way but not by a way or by the road
- Non-modifiable — No insertion or rearrangement: as a matter of fact but not as a small matter of fact
- Semantically opaque to varying degrees — Some are transparent (on the other hand), others fully idiomatic (by and large)
- Pragmatically specialised — Many serve discourse or social functions: greeting, hedging, turn-taking
Categories
| Type | Examples | Function |
|---|---|---|
| Discourse markers | by the way, as a matter of fact, on the other hand | Organise talk |
| Social formulae | how do you do, nice to meet you, see you later | Social rituals |
| Sentence builders | the thing is..., the point is... | Frame arguments |
| Proverbs/sayings | better late than never, actions speak louder than words | Cultural wisdom |
| Idioms (fully fixed) | kick the bucket, spill the beans | Figurative meaning |
Distinction from Other Multi-word Units
Fixed expressions differ from Semi-fixed Expressions in that they have no variable slots. They differ from Collocations in that collocations are probabilistic co-occurrences (words that tend to go together) while fixed expressions are invariable sequences. Many Idioms are fixed expressions, but not all fixed expressions are idiomatic — as a result is fixed and transparent.
Teaching Relevance
Nattinger and DeCarrico (1992) argued that fixed expressions are central to fluency because they reduce processing load — speakers retrieve them as single units rather than constructing them word by word. Lewis (1993) placed fixed expressions within the broader Lexical Approach, advocating that teachers raise awareness of these patterns through noticing activities, concordance work, and collocation exercises.
For learners, fixed expressions are best acquired as whole chunks. Attempts to translate them word for word typically fail, and grammatical analysis of their internal structure is often unhelpful (by and large defies standard parsing). Exposure through reading and listening, combined with explicit attention, is the most effective route to acquisition.
