Noam Chomsky's theory of linguistics, based on the fact that a single meaning may be expressed in different forms.

A theory of language proposed by Chomsky that explains how the structures of related statements are connected to each other.

the rules by which languages generate surface structures from deep structures, and deep structures from surface structures. (329)

the rules governing a proposition by Noam Chomsky that the most basic sentences, essentially SADDs are transformed into more complex sentences by a sequence of one or more transformations.

A generative grammar that uses rules which convert one phrase marker into another. The explicit rules ideally generate all and only the grammatical sentences of the language.

In linguistics, transformational grammar, or transformational-generative grammar (TGG), is grammar, especially of a natural language, that has been developed in a Chomskian tradition. Additionally, transformational grammar is the Chomskian tradition that gives rise to specific transformational grammars.
