The Arabic language is considered to exist in multiple forms: formal Arabic, commonly known as Modern Standard Arabic (a modern incarnation of Koranic or Classical Arabic), which is used in written documents and formal contexts; and dialectal variants, numbering some thirty vernacular speech forms, used in day-to-day contexts, and varying widely from country to country. The one spoken in Lebanon is called "Lebanese Arabic" or simply "Lebanese", and it is a type of Levantine Arabic, which, together with Mesopotamian Arabic, is classed by matter of convenience as a type of Northern Arabic.
