Arab Trick Makers, Saudi Arabia

The most popular Arab account holds that the word 'Arab' came from an eponymous father called Yarab, who was supposedly the first to speak Arabic. Al-Hamdani had another view; he states that Arabs were called GhArab (West in Semitic) by Mesopotamians because Arabs resided to the west of Mesopotamia; the term was then corrupted into Arab. Yet another view is held by Al-Masudi that the word Arabs was initially applied to the Ishmaelites of the "Arabah" valley.
The root of the word has many meanings in Semitic languages including "west/sunset," "desert," "mingle," "merchant," "raven" and are "comprehensible" with all of these having varying degrees of relevance to the emergence of the name. It is also possible that some forms were metathetical from ʿ-B-R "moving around" (Arabic ʿ-B-R "traverse"), and hence, it is alleged, "nomadic."
