"of or pertaining to blacks on the sea-islands of Georgia and South Carolina," 1739 (first attested as a male slave's proper name), of uncertain origin. Early 19c. folk etymology made it a shortening of Angola (homeland of many slaves) or traced it to a West African tribal group called the Golas.[Gullah etymology, Gullah origin, 英语词源]
