Abstract
This article seeks to highlight the general features of the Kufan school of grammar, which distinguished it from the Basran school and qualified it to be recognized as a distinct school of thought. It addresses the issue of disagreement that arose at the levels of methodology and terminology despite sharing a common source. The article aims to introduce the key figures of this school and emphasize their role in opening the door to grammatical debate in the Arab world. Thanks to their contributions, various schools of thought emerged in both the East and the West, leading to positive outcomes in terms of content and methodology. This development matured Arabic grammar, completed its structure, expanded its topics, diversified research methods, and broadened the approaches to reasoning among scholars in the field. As a result, numerous works were produced, enriching its content and establishing it as a legacy worthy of respect.
