This document provides historical background on the Arabic language. It discusses the distinction between Arabic vernaculars, localized varieties used for everyday speech, and Standard Arabic, used throughout the Arabic-speaking world for written communication. It then briefly outlines the evolution of Arabic from ancient Semitic roots and pre-Islamic dialects in Arabia, through the development of the Quran and early Islamic literature, to its spread across a vast region following the Muslim conquests. This led to a blending of old dialectal distinctions and the emergence of Standard Arabic as a lingua franca.
