Abstract

This research deals with the difference between Sibawaieh’s making in the Multiplicity of the grammatical faces in the case issues. And the making of late grammarians in that Multiplicity. It stands at the reality of the transformation from multiple faces to monotheism and reveals the causes of this multiplicity and how it appeared in contextual and linguistic conditions, and shows how it absent and defaced by all the late grammarians. The research shows that both makings relate to the nature of the language whose grammar was written, and the extent to which its people at all times need that plurality. During the time of Sibawaieh, it was needed while this is no longer the case for late grammarians. This led them to not care about the multiple settings.
