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.
Gulf Arabic
Gulf varieties' closest related relatives are other dialects native to the Arabian Peninsula, i.e. Najdi Arabic and Bahrani Arabic. Although spoken over much of Saudi Arabia's area, Gulf Arabic is not the native tongue of most Saudis, as the majority of them do not live in Eastern Arabia. There are some 200,000 Gulf Arabic speakers in the country, out of a population of over 30 million, mostly in the aforementioned Eastern Province.
