CORE DEFINITION

Chomsky's linguistic theory, which holds that human language ability is based on a finite set of grammatical rules, through "transformational" operations can generate an infinite number of grammatical sentences, emphasizing the distinction between deep structure and surface structure.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Reveals the generative mechanism of language. This theory explains why humans can understand and produce sentences never heard before—because we master generative rules, not a fixed repository of sentences.

Anchor fast decisions

Chomsky proposed that language is generated from "deep structure" to "surface structure" through transformational rules. The mechanism is that the human brain is endowed with "universal grammar," using finite rules to generate infinite sentences.
