جذور التفكير الوظيفي في الفكر اللغوي العربي القديم

As it appears from the title of the research, its topic revolves around an important and sensitive issue, which is the issue of re-reading the Arabic linguistic heritage, and linking it to modern linguistic thought in order to highlight its scientific and civilized value. Enriching the modern linguistic lesson with conceptual and methodological data derived from the ancient linguistic heritage. We have seen that we treat this subject according to three axes: The first axis: we dealt with the concept of heritage linguistics and its scientific foundations. As for the second axis, we dealt with the theoretical and methodological foundations of modern functional linguistic thought. As for the third axis: we dealt with the disclosure of some aspects of functional thinking in the Arabic linguistic heritage. Finally, we conclude that the ancient Arabic linguistic thought was, in its entirety, a functional thought by dealing with language as a tool for communication.
