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.
Tunisian Arabic
Nowadays and due to dialect leveling, the main dialect varieties of Tunisian Arabic are Northwestern Tunisian (also spoken in Northeastern Algeria), southwestern Tunisian, Tunis dialect, Sahil dialect, Sfax dialect and southeastern Tunisian. All of these varieties are Hilalian excepting the Sfax one.
