'abominator' originates from Latin, specifically the word 'abominari,' where 'ab-' meant 'away from' and 'ominari' meant 'to forebode or predict.'

'abominari' transformed into the Old French word 'abominer,' and eventually became the modern English word 'abominate' through Middle English.

Initially, it meant 'to forebode or predict something bad,' but over time it evolved into its current meaning of 'to detest or loathe intensely.'
