oeste m. (Noun) "west"
Late 15th cent. Old Spanish oüeste. Borrowed from French oeste 'id.,' itself borrowed from a Germanic source (compare English west). From Proto-Germanic *westera- "west," "western." The first element *wes- is of uncertain etymology, probably *u̯e-kwsp- "evening;" the second element *-tera- is a comparative suffix used in directions from Proto-Indo-European *-tero- (see -tr-).
