Abstract
If the two terms within the theory (generative and transformative) are so closely related that they are not separated unless the need requires, but still each of them can be defined as follows: Generative rules: are the rules that generate acceptable sentences in the language, while they do not generate sentences that are unacceptable in the language; Because language, in Chomsky's words, consists of "(a finite or infinite set of sentences), every sentence of finite length and composed of a finite set of elements, and all natural languages in their spoken or written form conform to this definition, because every natural language consists of a finite set of sounds (or a finite set of written symbols), yet it produces or generates endless sentences. Generative, then, is relative to the production of sentences in a large and infinite amount, noting that it is linked in its basis to the mental aspect of the production of sentences or what is called the deep structure of language. As for the transformational rules: they are the rules that transform the deep structure of the language into the structure by means of various elements: such as deletion, addition, and order change. Meaning, it moves from the mental stage to the materialistic stage in written and the spoken. As for the reason for calling it chomsky's theory, According to the American researcher Avram Noam Chomsky the founder of the generative transformational theory in the language, Accordingly, we must introduce the father of this modern theory of language, with a focus on the influences that helped Chomsky to produce an independent linguistic approach.
