Compositionality
Pattern
Meaning of whole = f(parts + combination rules) — or breakdown thereof
Definition
The principle that the meaning of a complex expression is determined by the meanings of its parts and the way they are combined. When compositionality breaks down (idioms, metaphors), the phrase means something its parts don't predict.
Examples
Example 1
'Kick the bucket' — compositionally this means striking a pail with one's foot, but idiomatically it means 'to die.' The idiomatic meaning is non-compositional.
AI Detection Note
AI generally produces highly compositional language — phrases whose meaning is entirely predictable from their parts. Non-compositional language (creative metaphors, novel idioms, catachresis) is rare in AI output.
