Ostrogoth (n.)
c. 1600, one of the "East Goths," who conquered Italy late 5c. and established, under Theodric, a kingdom there that lasted from 493 to 555 C.E., from Late Latin Ostrogothæ, from Germanic, perhaps literally "eastern Goths" from Proto-Germanic *austra- "east" (from PIE root *aus- (1) "to shine," on the notion of "toward sunrise"), but according to Klein's sources the first element might be literal: "shining" or "splendid." For second element, see Goth, and compare Visigoth.
