Arabic is a Central Semitic language that first emerged in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. It is named after the Arabs, a term initially used to describe peoples living in the area bounded by Mesopotamia in the east and the Anti-Lebanon mountains in the west, in northwestern Arabia, and in the Sinai Peninsula. Arabic is classified as a macro-language comprising 30 modern varieties, including its standard form, Modern Standard Arabic, which is derived from Classical Arabic.
