athwart

Origin

From Late Middle English athwert, athirt, from a- (prefix meaning ‘in the direction of, toward’) + thwert (“crosswise; (cooking) across the grain”, adverb). Thwert is derived from thwert (“crosswise, transverse; counter, opposing; contrary, obstinate, stubborn”, adjective), borrowed from Old Norse þvert (“across, athwart”), originally the neuter form of þverr (“across, transverse”), from Proto-Germanic *þwerhaz (“cross; adverse”) (altered or influenced by Proto-Germanic *þweraną (“to stir; to swirl; to turn”)), from Proto-Germanic *þerh-, probably from Proto-Indo-European *terkʷ- (“to spin; to turn”). The English word is analysable as a- (prefix meaning ‘in the direction of, toward’) + thwart (“placed or situated across something else”). Cognates * Scots athort (“athwart”)
