'therapy' originates from Greek, specifically the word 'therapeia,' where 'therapeuein' meant 'to attend, do service, take care of.'

'therapeia' transformed into the Latin word 'therapia,' and eventually became the modern English word 'therapy' through Old French 'therapie.'

Initially, it meant 'to take care of or attend to,' but over time it evolved into its current meaning of 'treatment intended to relieve or heal a disorder.'
