This study examines the foundations of Arabic grammar through philosophical influences that permeated linguistic thought since the Abbasid translation movement. It explores the relationship between grammar, as a linguistic science rooted in textual evidence, and philosophy, as a rational discipline seeking the causes and essences of things. The research employs a historical-analytical method, linking early grammatical texts to contemporary philosophical movements. It concludes that Arabic grammar, though deeply rooted in native linguistic tradition, employed philosophical and logical tools in its later theoretical development without losing its authenticity or linguistic foundation.
