In the present article relationship of thought and language for the priority aspect, from al-Fārābī’s point of view is discussed. Based on the three meanings of nuṭq (: speech), speaking is a process in which human soul is concerned with the three levels of intellectual faculty, apprehended objects in the mind as well as the expression by language. Then, this reveals a close and inseparable relationship between language and thought. Again it is suggested that relying on the tripartite theory of (...) word, world, and intelligibles, by Al-Fārābī, at the time of the process of speaking, human soul makes use of all knowledge either acquired previously, or the knowledge obtaining as the content of experience in the actual speech situation. Thus, in connection with the priority aspect of the relationship between thought and language, I suppose, in an analytical aspect of priority, there is no priority relation between them, namely, they are interdependent. It can be supported by this view that thought and gaining knowledge are continued even while speaking. Besides, it has been argued that the human soul, as the chief agent of thinking and obtaining knowledge, is not completely passive; then human thought cannot have transcendental supremacy over language.
