Mohammed ibn Adjurrum

Ibn Ād̲j̲urrūm or (Berber: Ajeṛṛom or Ajerrum) and his full name: Abu Abdallah Mohammed ibn Mohammed ibn Dawud ibn Adjurrum es-Sanhadji (1273–1323) was a famous grammarian from Morocco whose synopsis of Arabic grammar Al-Muqadimma al-Adjurrumiya fi Mabadi Ilm al-Arabiya (most commonly abbreviated to al-Ajurrumiyya) was published in twelve different European versions and editions. As his name indicates he was of Berber Sanhadja origin, but little is known about his life, except that he died in Fes. "Adjurrum" is said to mean the "poor Sufi" in the Senhaja Berber language.

Ibn Adjurrum is the author of a celebrated Muḳaddima which bears his name, a little treatise of a few pages in which he sets out the system of the iʿrāb of words. This summary syntax, easy to memorize, has enjoyed to the present day great popularity in all the Arabic-speaking countries, in the west as well as in the east. Because of its extreme conciseness, the Muḳaddima has provoked about 60 commentaries by subsequent grammarians, which testify to its wide diffusion among teachers. The Muḳaddima has been known in Europe since the 10th/16th century, being one of the first treatises available to Arabists for the study of the Arabic grammatical system. It has been published a dozen times and translated into most European languages. It is to be remarked that al-Suyuti (Bug̲h̲ya, 102) considers Ibn Ād̲j̲urrūm to represent the Kūfa grammatical school, basing himself on the fact that he uses the term k̲h̲afḍ , and that he considers the imperative to be muʿrab and the particle kayfamā to govern the d̲j̲azm.
