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
"Arabic" usually designates one of three main variants: Classical Arabic, Modern Standard Arabic and "colloquial" or "dialectal" Arabic. Classical Arabic is the language found in the Quran, used from the period of Pre-Islamic Arabia to that of the Abbasid Caliphate. Theoretically, Classical Arabic is considered normative, according to the syntactic and grammatical norms laid down by classical grammarians (such as Sibawayh) and the vocabulary defined in classical dictionaries (such as the Lisān al-ʻArab). In practice, however, modern authors almost never write in pure Classical Arabic, instead using a literary language with its own grammatical norms and vocabulary, commonly known as Modern Standard Arabic (MSA).
