Nasr ibn 'Asim al-Laythi

Naṣr bn ʿĀṣim al-Laythī or al-Duʾalī (Arabic: نصر بن عاصم اليثي; died 708/709) was an Arabic grammarian from Basra.[1] He is known as one of the first Arabic grammarians.[2]

Nasr ibn 'Asimm along with another famous Arabic grammarian from Basra, Yahya ibn Ya'mar, were asked to solve problems within the language. Nasr and Yahya invented a system of dots to distinguish each of these letters.[2]

Regarding who is the father of Arabic grammar: most scholars are of the view that Arabic grammar was invented by Abu al-Aswad al-Duʾalī, and that he had been taught by the Commander of the Faithful, Ali ibn Abi Talib. Others say that Naṣr ibn 'Āṣim developed grammar.
