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 morphology
There are significant differences in morphology between Tunisian and Standard Arabic. Standard Arabic marks 13 person/number/gender distinctions in the verbal paradigm, whereas the dialect of Tunis marks only 7 (the gender distinction is found only in the third person singular). Nomadic Tunisian Arabic dialects also mark gender for the second person in singular, in common with most spoken varieties of Arabic elsewhere in the Arabic world.
