2.1. The Types of Components

The syntactic component has two components: the base and the transformational component. This organization is outlined below:

         A. Syntactic Component

                  (i) The Base

                        (a) PSG rules

                         (b) Lexicon (with rules of lexical insertion)

                  (ii) Transformational Component

        B. Semantic Component

        C. Phonological Component

In this model Chomsky added the Semantic component because meaning should have the same formal treatment as syntax. Semantics was introduced as an essential part of the grammatical analysis of a language.
