'therapeutics' originates from Greek, specifically the word 'therapeutikos,' where 'therapeuein' meant 'to attend to' or 'to treat.'

'therapeutikos' transformed into the Latin word 'therapeuticus,' and eventually became the modern English word 'therapeutics' through Middle English.

Initially, it meant 'to attend to or treat,' but over time it evolved into its current meaning of 'the branch of medicine concerned with treatment and cure.'
