What is an Arab?

[Adisa]

As I read in one of the dictionaries, the etymology of the word Arab, lead back to the Greek word "Arap." When I typed in the word Arap into wikipedia, I was taken to "Isaaq"

 The Isaaq (also Isaq, Ishaak) (Somali: Reer Sheik Isaxaaq, Arabic: إسحاق‎) are one of the main clans of the Somali people. Members principally live in the northwestern Somaliland region of Somalia and the Somali Region of Ethiopia.

When I typed in the word "Arab" into wikipedia, I read that originally, "Arabs" were synonymous with the Tribes of Arabia, until the Arabisation of people outside the Arabian peninsula, mostly during the Abbasid Caliphate. Therefore, all uses of the word "Arab" prior to the 6th century, and most of those prior to the 13th century AD refer specifically to Arabians. Later uses of the word "Arab" could refer to any individual whose familial ancestry corresponds to the wider linguistic and panethnic definitions of Arabs. The earliest documented use of the word "Arab" to refer to a people appears in the Monolith Inscription, an Akkadian language record of the 9th century BC Assyrian Conquest of Syria, which referred to Bedouins of the Arabian peninsula underKing Gindibu who fought as part of a coalition opposed to the Assyrian empire.^[31]
