abomination comes from Latin abōminātiō, abōminātiōn- ('an abhorrence'), from abōminārī ('to abhor as an ill omen'), from ab- ('away') + ōmen ('omen'). Morphologically, the word is transparent as a compound: its parts remain visible in the modern spelling, while the older history of those parts supplies the deeper ancestry. In modern use, the noun sense is "a thing that causes disgust or hatred", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes related English forms such as abominate, abominable, showing how the same base continues to support neighboring English vocabulary. The principal historical forms in the chain include Latin abōminātiō, Latin ōmen, which anchor the explanation in named linguistic material.
