Arabic is perhaps spoken by as many as 420 million speakers (native) in the Arab world, making it one of the six most-spoken languages in the world. Arabic also is a liturgical language of 1.6 billion Muslims. It is one of six official languages of the United Nations.
The modern written Arabic language (Modern Standard Arabic) is derived from the language of the Quran (known as Classical Arabic or Quranic Arabic). It is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the official language of 26 states and the liturgical language of Islam. Modern Standard Arabic largely follows the grammatical standards of Quranic Arabic and uses much of the same vocabulary. However, it has discarded some grammatical constructions and vocabulary that no longer have any counterpart in the spoken varieties, and has adopted certain new constructions and vocabulary from the spoken varieties.
