linguistic research program proposed by N. Chomsky; radically revises the Government and Binding approach; asserts that Universal Grammar is a “perfect” system, i.e. optimal according to several global metrics; abandons concepts such as government

framework for describing the syntax and semantics of natural languages

rewrite rule used to describe a given language's syntax, used to break down a natural language sentence into its syntactic categories (both lexical and phrasal); used in transformational grammar; first proposed by Noam Chomsky in 1957
