Mediterranean

"the sea between southern Europe and northern Africa," c.1400, from Late Latin Mediterraneum mare "Mediterranean Sea" (7th-century), from Latin mediterraneus "midland;" the original sense being of "sea in the middle of the earth," from medius "middle" (see medial (adj.)) + terra "land, earth" (see terrain). The Old English name was Wendel-sæ, so called for the Vandals, Germanic tribe that settled on the southwest coast of it after the fall of Rome. The noun meaning "a person of Mediterranean race" is from 1888.
