'analgetic' originates from Greek, specifically the word 'analgētikos,' where 'an-' meant 'without' and 'algos' meant 'pain.'

'analgētikos' transformed into the Late Latin 'analgeticus,' and eventually became the modern English word 'analgetic.'

Initially, it meant 'without pain' or 'removing pain,' and this meaning has largely remained the same in modern usage as 'relieving pain.'
