1 Spanish: nickname from abad ‘priest’ (from Late Latin abbas ‘priest’, genitive abbatis, from the Aramaic word meaning ‘father’). The application is uncertain: it could be a nickname, an occupational name for the servant of a priest, or denote an (illegitimate) son of a priest.2 Muslim: from a personal name based on Arabic ῾Abbād ‘devoted worshiper’ or ‘servant’. The banu (tribe) ῾Abbād claims descent from the ancient Lakhmid kings of al-Ḥirah. The founder of the ῾Abbadids of Seville was Muhammad bin ῾Abbād ( 1023–42 ), whose son ῾Abbād succeeded his father as chamberlain to the pretended khalif, but was soon ruling in his own right under the honorific title al-Muta῾id ‘petitioner for justice (from Allah)’.
