'carnivorism' originates from Latin, specifically the word 'carnivorus,' where 'carni-' meant 'flesh' and '-vorus' meant 'devouring.'

'carnivorus' transformed into the English word 'carnivore,' and eventually became the modern English word 'carnivorism.'

Initially, it meant 'flesh-devouring,' but over time it evolved into its current meaning of 'the practice of eating meat.'
