Moroccan Arabic (العربية المغربية الدارجة Moroccan vernacular Arabic), also known as Darija (الدارجة), is the dialectal, vernacular form or forms of Arabic spoken in Morocco. It is part of the Maghrebi Arabic dialect continuum and as such is mutually intelligible to some extent with Algerian Arabic and to a lesser extent with Tunisian Arabic. It is spoken by 90.9% of the population of Morocco. While Modern Standard Arabic is used to varying degrees in formal situations such as religious sermons, books, newspapers, government communications, news broadcasts and political talk shows, Moroccan Arabic is the predominant spoken language of the country and has a strong presence in Moroccan television entertainment, cinema and commercial advertising. Moroccan Arabic has many regional dialects and accents as well, with its mainstream dialect being the one used in Casablanca, Rabat, Tangier, Marrakesh and Fez, and therefore it dominates the media and eclipses most of the other regional accents.
SIL International classifies Moroccan Arabic, Hassaniya Arabic and Judeo-Moroccan Arabic as different varieties of Arabic.
Moroccan Arabic was formed of several dialects of Arabic belonging to two genetically different groups: pre-Hilalian and Hilalian dialects.
Pre-Hilalian dialects are a result of early Arabization phases of the Maghreb, from the 7th to the 12th centuries, concerning the main urban settlements, the harbors, the religious centres (zaouias) as well as the main trade routes. The dialects are generally classified in three types: (old) urban, "village" and "mountain" sedentary and Jewish dialects. In Morocco, several pre-Hilalian dialects are spoken:
Urban dialects: Old dialects of Fes, Rabat, Salé, Taza, Tétouan, Wezzan, Chefchaouen, Tangier, Asilah, Larache, Ksar el-Kebir, Meknes and Marrakesh.
Jebli dialects: Dialects of the southern and western Rif and the plains of northwestern Morocco, spoken by the Jebala, Masmuda, Ghomara, and Zenata.
