TG grammar
and/or
Chomsky

TG stands for transformational - generative.

CJ
TG Grammar allows believes that potential learner minds can transform / change / modify any pre-learned structure/ sentence or even words, and generate / make / create their own novel / different expressions in the oral or written form. This is purely a cognitive based inferenctial approach.

The major advantage of this logically inferred approach for ELT purposes is that the teachers of Englsih and Students are freed from the tedious task of teaching / learning all the structues of Englsih to develop communicative ability as suggested by structural approach.
