The Historical Origins of Arabic Grammar: Abu al-Aswad al-Du’ali and the Development of the Basrah Tradition

The historical origins of Arabic grammar (nahw) involve interconnected developments in linguistic scholarship, Qur’anic recitation, and Arabic writing. This study examines the emergence of grammatical thought during the first century after the Hijrah, focusing on contributions attributed to Abu al-Aswad al-Du’ali, Yahya ibn Ya‘mar, and Nasr ibn ‘Asim, alongside the subsequent development of the Basrah grammatical tradition. It aims to contextualize early grammatical initiatives, critically examine traditional accounts, and explain the relationship between early linguistic practices and later grammatical systematization. A qualitative historical approach based on library research was employed, drawing on classical Arabic sources and modern scholarly literature. The analysis examined historical narratives and scholarly interpretations concerning the circumstances, attribution, and development of early grammatical knowledge. The findings identify several interconnected factors associated with the emergence of nahw: the expansion of Islam, the increasing use of Arabic among linguistically diverse communities, the preservation of Qur’anic recitation, and concerns about linguistic error (lahn). Abu al-Aswad al-Du’ali occupies a prominent position in traditional narratives, while Yahya ibn Ya‘mar and Nasr ibn ‘Asim are associated with subsequent developments in grammatical inquiry and Arabic writing. The analysis distinguishes naqṭ al-i‘rāb, which marks vowel or inflectional features, from i‘jām al-ḥurūf, which differentiates letters through dots. The later development of the Basrah tradition, particularly the systematic scholarship associated with Sibawayh, is interpreted as a gradual intellectual process. The study concludes that accounts of Arabic grammar’s origins require critical historical interpretation because their attributions and details vary. Its contribution lies in connecting early linguistic practices with subsequent grammatical scholarship while maintaining distinctions among different forms of innovation. Further comparative research should clarify the chronology and transmission of early Arabic grammatical knowledge.
