abhor: [15] Abhor comes from Latin abhorrēre, which literally meant ‘shrink back in terror’ (from the prefix ab- ‘away’ and horrēre ‘tremble’ – which also gave English horror and horrid). The word used to have this intransitive meaning ‘be repelled’ in English too, but the transitive usage ‘loathe’ (which was probably introduced from Old French in the 15th century) has completely taken its place. => horrid, horror[abhor etymology, abhor origin, 英语词源]
