ما اتفق فيه الخليل وسيبويه وما اختلفا فيه

Abstract

In Sibawaihs’ book El-kitaab"El-khalil ben Ahmed El-farahidi points of view seems to be clear in different linguistic domains. Since Sibawaih is a student of EL-khalil he used to agree with him sometimes and disagree with him in others. The word disagreement does not mean that Sibawaih wants to prove that his teacher is totally wrong but to show that there is another view. This view serves the linguistic domain positively. We focus on collecting the previous points of view making the researchers getting what they want.
