What is the use of Transformational Grammar?
Transformational grammar is used routinely to understand the grouping of words in a particular context. For example look at the sentences, “John wrote a poem on the spring season” and “A poem on the spring season was written by John”. According to Chomsky these sentences originate from a deeper and more abstract grammatical structure. Transformational grammar explains how actual sentences evolve by manipulating the common form of sentence structures. A number of different theories have since evolved but they are all based on the Chomsky’s original theory of transformational grammar.
