Construction Grammar

Construction grammar is a family of linguistic frameworks that treat the basic unit of grammatical knowledge not as an abstract rule but as a construction — a pairing of form and meaning stored directly in the speaker's linguistic knowledge. Where generative grammar derives sentences by applying rules to abstract categories, construction grammar holds that speakers know thousands of form-meaning pairings directly, from morphemes to idioms to complex clause patterns, and that all of these are constructions in the same fundamental sense.

The framework emerged from work by Charles Fillmore, Paul Kay, and Adele Goldberg in the 1980s and 1990s as a direct response to the poverty of formal semantics in capturing idiomatic and partially regular patterns that rule-based grammars struggle with. The English caused-motion construction (She sneezed the napkin off the table) licenses verbs in argument structures their standard meaning does not support — a fact that construction grammar captures by positing that the construction itself contributes meaning, not merely the verb.

The radical implication: there is no principled distinction between grammar and lexicon. Both are inventories of constructions, differing in schematicity and productivity, not in kind. Syntax, on this view, is not a separate module but a continuum of stored patterns that ranges from fixed phrases to fully schematic clause templates. This threatens the modularity assumption that underpins cognitive science's division of the language faculty into separate components.

Whether construction grammar constitutes a complete theory of language or a useful descriptive vocabulary that avoids the hard questions about language acquisition remains contested.
