'abattoir' originates from French, specifically the word 'abattre,' where 'abattre' meant 'to fell or knock down.'

'abattre' transformed into the French word 'abattoir,' and eventually became the modern English word 'abattoir.'

Initially, it meant 'a place where animals are knocked down,' but over time it evolved into its current meaning of 'a facility for slaughtering animals.'
