Abstract: Translation is the basis of communication between cultures، and the carrier of knowledge of the cultural and scientific achievements of the era. It has contributed a great deal to the development of medical sciences among the ancient Arabs and the Arabs in recent times because they relied on translating the mothers of medical books of various civilizations in the development of this field of science، and this is what prompted me to interest in studying words The foreign language in the medical books of the Abbasid era، and the material of this research came in the Abbasid era، in which Arabization had a wide field in developing the verbal wealth of Arabic. The research explained the Arabs’ approach to using foreign words as they are or by changing them، or by derivation from them or by analogy with them.
