Word Origin & History
west
O.E. west "in or toward the west," from P.Gmc. *wes-t- (cf. O.N. vestr, O.Fris., M.Du., Du. west, O.H.G. -west, only in compounds, Ger. west), from PIE *wes- (source of Gk. hesperos, L. vesper "evening, west"), perhaps an enlarged form of base *we- "to go down" (cf. Skt. avah "downward"), and thus lit. "direction in which the sun sets." Cf. also High Ger. dial. abend "west," lit. "evening." Fr. ouest, Sp. oeste are from Eng. West used in geopolitical sense from World War I (Britain, France, Italy, as opposed to Germany and Austria-Hungary); as contrast to Communist Russia (later to the Soviet bloc) it is first recorded in 1918. West Indies is recorded from 1555. The verb wester "to go west" is recorded from c.1374; westerly first recorded 1577 in both its (somewhat contradictory) senses of "coming from the west" and "facing toward the west."
