sentences:  This term was introduced by Marçais  and Colin, who argued that the first arabicization of Northern Africa took place long before the migration of the famous Yemeni Bani Hilal tribe in 12th-13th centuries.The pre-Hilali group consists of the Jebli dialect together with the dialects spoken in other North African cities.The Jbala, together with several groups of population, inhabiting the Algerian and Tunisian part of the Tell Atlas, were the first Imazighen (Berbers) who arabicised their language, probably due to their proximity to the old route that once connected Fes (as well as Tlemcen and Constantine) with Mediterranean ports, especially with those located in al-Andalus.
