Generative Grammar

Generative grammar is Noam Chomsky's framework for describing linguistic competence as a system of formal rules that recursively generate all and only the grammatical sentences of a language. Introduced in Syntactic Structures (1957), the approach treats grammar as a computational procedure — a finite set of operations that can produce an infinite set of structured outputs.

The core claim: knowing a language is not knowing a list of sentences but knowing the rules that generate them. A native speaker can produce and understand sentences they have never encountered, which implies they have internalized a generative system, not a static inventory. Linguistics, on this view, is the study of the formal properties of these generative systems.

The framework revolutionized linguistics by making syntax mathematically precise and empirically testable. It also entrenched a division between syntax (structure) and other dimensions of language (meaning, use, variation) that later frameworks challenged. Whether generative grammar discovered the structure of linguistic competence or imposed a formalist template onto linguistic data remains debated.
