Abstract
This research is concerned with the criticism and analysis to what Khalil Ahmed Amaayra denied on the rules and verdicts of old Grammarians. That is he accounted for the possible deletion of the case endings in Arabic parsing. His different ideas were bused on the modern theories of grammar that are adopted by Chomsky – whose theory is called the generative transformational. Chomsky's theory depends on four syntactic trans formations they are addition, deletion, order, substitution and intonation.
The researcher has found differences of verdicts and meaning. Even in AL-Jurjanies' ideas are part of syntax.
It has been proven that the English theories of grammar cannot be applied on Arabic for its peculiar syntactic properties.
