Mubarrad, or Mobarrad [Abu-1 `Abbas Mahommed ibn Yazid ul-Azdi] (c. 826-898), Arabian grammarian, was born in Basra, and became the leader of the Basran grammarians against the Kufan school. His judgment, however, was independent, as is shown by his attack on some points in the grammar of Sibawaihi, the greatest writer of his own school. He died at Bagdad.
His main work is the grammatical one known as the Kamil (Perfect), which has been edited by W. Wright (Leipzig, 1864 seq.), and published at Constantinople (1869) and Cairo (1891). Two or three other works exist in MS.; cf. C. Brockelmann, Gesch. der arabischen Litteratur, i. 109 (Weimar, 1898). (G. W. T.)
