Methodology of TGG

The description of sentences in TGG is based on the operation of several types of rules which constitute the components of grammar. It is important to note that there are differences between the two versions of TGG, the Classical Theory of 1957 and the Standard Theory of 1965, in the types, the number, the status and the order of components.

1. The Classical Theory

In this version, grammar consisted of three components:

1. The phrase structure component ( consists of phrase structure rules)
2. The transformational component ( consists of transformational rules)
3. The morphophonemic component (consists of morphophonemic rules)

The following diagram shows how the grammar outlined in this version was organised:
