Sibawayh (Arabic: سِيبَوَيْه IPA: [siːbæˈwæjh] (also pronounced [siːbæˈweː(h)] in many modern dialects) Sībawayh; Persian: سیبُویه Sēbūyeh [seːbuːˈje]; c. 760–796), whose full name is Abu Bishr Amr ibn Uthman ibn Qanbar al-Basri (أَبُو بِشْر عَمْرو بْن عُثْمَان بْن قَنْبَر ٱلْبَصْرِيّ, ʾAbū Bišr ʿAmr ibn ʿUṯmān ibn Qanbar al-Baṣrī), was a Persian leading grammarian of Basra and author of the Third book on Arabic grammar. His famous unnamed work, referred to as Al-Kitāb, or "The Book", is a five-volume seminal discussion of the Arabic language.
Ibn Qutaybah, the earliest extant source, in his biographical entry under Sibawayh simply wrote:
He is Amr ibn Uthman, and he was mainly a grammarian. He arrived in Baghdad, fell out with the local grammarians, was humiliated, went back to some town in Persia, and died there while still a young man.
The tenth-century biographers Ibn al-Nadim and Abu Bakr al-Zubaydi, and in the 13th-century Ibn Khallikan, attribute Sibawayh with contributions to the science of the Arabic language and linguistics that were unsurpassed by those of earlier and later times.
