"in or toward the west, in a westerly direction," from Proto-Germanic *west- (source also of Old Norse vestr, Old Frisian, Middle Dutch, Dutch west, Old High German -west, only in compounds, German west), which is of uncertain origin. Perhaps from PIE *wes-, reduced form of *wes-pero- "evening, night" (source also of Greek hesperos, Latin vesper "evening, west;" see vesper).
