+그의 저서 ''Syntactic Structures''에서 시작되는 촘스키 언어학은 구조적인 언어학에 도전하며, 변형 문법을 소개한다. 이 이론은 일반 문법에 의해 특징지을 수 있는<ref>특히 변형문법과 같이 확장된 [[문맥자유문법]]</ref>  통사론을 가지는 말(단어의 순서)로 여긴다.
+Children are hypothesized to have an innate knowledge of the basic grammatical structure common to all human languages (i.e., they assume that any language which they encounter is of a certain restricted kind). This innate knowledge is often referred to as universal grammar. It is argued that modeling knowledge of language using a formal grammar accounts for the "productivity" of language: with a limited set of grammar rules and a finite set of terms, humans are able to produce an infinite number of sentences, including sentences no one has previously said. He has always acknowledged his debt to Pāṇini for his modern notion of an explicit generative grammar. This is related to Rationalist ideas of a priori knowledge, in that it is not due to experience.
+The Principles and Parameters approach (P&P)—developed in his Pisa 1979 Lectures, later published as Lectures on Government and Binding (LGB)—make strong claims regarding universal grammar: that the grammatical principles underlying languages are innate and fixed, and the differences among the world's languages can be characterized in terms of parameter settings in the brain (such as the pro-drop parameter, which indicates whether an explicit subject is always required, as in English, or can be optionally dropped, as in Spanish), which are often likened to switches. (Hence the term principles and parameters, often given to this approach.) In this view, a child learning a language need only acquire the necessary lexical items (words, grammatical morphemes, and idioms), and determine the appropriate parameter settings, which can be done based on a few key examples.
+Proponents of this view argue that the pace at which children learn languages is inexplicably rapid, unless children have an innate ability to learn languages. The similar steps followed by children all across the world when learning languages, and the fact that children make certain characteristic errors as they learn their first language, whereas other seemingly logical kinds of errors never occur (and, according to Chomsky, should be attested if a purely general, rather than language-specific, learning mechanism were being employed), are also pointed to as motivation for innateness.
+More recently, in his Minimalist Program (1995), while retaining the core concept of "principles and parameters", Chomsky attempts a major overhaul of the linguistic machinery involved in the LGB model, stripping from it all but the barest necessary elements, while advocating a general approach to the architecture of the human language faculty that emphasizes principles of economy and optimal design, reverting to a derivational approach to generation, in contrast with the largely representational approach of classic P&P.
+Chomsky's ideas have had a strong influence on researchers investigating the acquisition of language in children, though some[specify] researchers who work in this area today do not support Chomsky's theories, instead advocating emergentist or connectionist theories reducing language to an instance of general processing mechanisms in the brain.
+He also theorizes that unlimited extension of a language such as English is possible only by the recursive device of embedding sentences in sentences.[citation needed]
+His best-known work in phonology is The Sound Pattern of English (1968), written with Morris Halle (and often known as simply SPE). This work has had a great significance for the development in the field. While phonological theory has since moved beyond "SPE phonology" in many important respects, the SPE system is considered the precursor of some of the most influential phonological theories today, including autosegmental phonology, lexical phonology and optimality theory. Chomsky does not publish on phonology anymore.-->
