ABSTRACT
An abbreviated name for the model proposed in Chomsky’s (1965) book Aspects of the Theory of Syntax, in which he revised his suggested model for transformational grammar published in Syntactic Structures in 1957. The most important changes and extensions of the aspects model are: (a) the differentiation between the terms competence and performance ( competence vs performance), grammaticality and acceptability, surface structure and deep structure; (b) instead of generalized transformations, recursiveness is part of the base components of the grammar; (c) the lexicon is added to the grammar as a base component and the level of semantics is treated as an interpretive component. transformational grammar for the extensions of the aspects model.
