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.
Arabic
Within the non-peninsula varieties, the largest difference is between the non-Egyptian North African dialects (especially Moroccan Arabic) and the others. Moroccan Arabic in particular is hardly comprehensible to Arabic speakers east of Libya (although the converse is not true, in part due to the popularity of Egyptian films and other media).
