Grammatical Reasoning in Inflected Nouns According to Ibn al-Hajib and the Commentators of Al-Kafi in the Seventh Hijri Century

Abstract

Grammarians have sought the reasons from the speech of the Arabs and derived their rules and analogies from it, following the differences in their dialects and the grammatical indicators they provide. In turn, this leads to variations in the application of the rules' principles, resulting in the emergence of secondary and tertiary reasons.   In its early stages, grammatical causation was characterized by simplicity, reflecting both the simplicity of learners’ questions and the limited objectives for which such explanations were provided. However, as grammatical schools became established and their foundations solidified, scholars began to differ in their views. This led to disputes among them on numerous issues, prompting each school to defend its perspective through arguments and evidence aimed at refuting opposing views that challenged their interpretations. As a result, grammatical causation expanded significantly, encompassing nearly every grammatical rule and principle. Each rule came to be associated with a form of justification—whether brief or extensive, straightforward or complex—depending on the grammarian’s proficiency, linguistic mastery, argumentative skill, and desire to demonstrate intellectual sophistication. Grammarians start to explain everything related to syntactic structure, among them Ibn al-Hajib, who composed his 'Kafiyah,' a concise and valuable grammatical work. Due to its scientific significance in the field of grammar, the book encouraged grammarians to hasten to explain it and study it closely.

What distinguished Ibn al-Hajib in his educational research approach, which included the chapters of the book dividing 'cause' into the parts of speech, namely nouns, verbs, and letters, is what the commentators of Al-Kafiyah have followed. This research was limited to the chapter on nouns to address a model of these instances. In it, he followed the descriptive-analytical method, which Ibn al-Hajib and the commentators of Al-Kafiyah adopted in the seventh century AH to follow the visual method in directing causes. Thus, their reasoning displayed a philosophical and logical perspective, which is a distinguishing feature of the methodology of Ibn al-Hajib and the commentators of Al-Kafiyah.

The integration of logic and philosophy into Arab intellectual life had a significant impact on the expansion and elevation of grammatical causation, moving it beyond its original simplicity and purpose. Consequently, analogical and dialectical causes emerged alongside pedagogical ones. Scholars of the seventh century AH undertook efforts to review and weigh these types of causation, as demonstrated by Ibn al-Ḥājib and the commentators of the Kāfiyah, whose work played a prominent and effective role in the development of grammatical theory.
