Varieties of Arabic
There are many varieties of Arabic (also called dialects of Arabic or vernacular languages) in existence. Arabic is a Semitic language within the Afroasiatic family that originated on the Arabian Peninsula. It is classified as a macrolanguage comprising 30 modern varieties, including its standard form. The largest divisions occur between the spoken languages of different regions. Some varieties of Arabic in North Africa, for example, are not easily comprehensible to an Arabic speaker from the Levant or the Persian Gulf. Within these broad regions further and considerable geographic distinctions exist, within countries, across country borders, even between cities and villages.
Sudan
Sudan has 597 groups that speak over 400 different languages and dialects. Sudanese Arabs are by far the largest ethnic group in Sudan. They are almost entirely Muslims; while the majority speak Sudanese Arabic, some other Arab tribes speak different Arabic dialects like Awadia and Fadnia tribes and Bani Arak tribes who speak Najdi Arabic; and Rufa'a, Beni Ḥassān, Al-Ashraf, Kinanah and Rashaida who speak Hejazi Arabic. In addition, the Western province comprises various ethnic groups, while a few Arab Bedouin of the northern Rizeigat and others who speak Sudanese Arabic share the same culture and backgrounds of the Sudanese Arabs.
