among the Turks, signifies a governor of a country or town. The Turks write it begh, or bek, but pronounce it bey.
This word is particularly applied to a lord of a banner, whom, in the same language, they call sangiac-beg or bey. Every province in Turkey is divided into seven sangiacs, or banners, each of which qualifies a bey; and these are all commanded by the governor of the province, whom they also call begler-beg, that is, lord of all the beghs or beys of the province: These beys are much the same as bannerets were formerly in England.
BEY of Tunis, the same with the dey of Algiers, is the prince or king of that kingdom.
