'anaeretic' originates from Greek, specifically the word 'anairetikos,' where 'anairein' meant 'to take up, remove.'

'anairetikos' transformed into the Late Latin word 'anaereticus,' and eventually became the modern English word 'anaeretic.'

Initially, it meant 'removing or taking away,' but over time it evolved into its current meaning of 'causing evacuation of the bowels.'
