'surgery' originates from Greek, specifically the word 'kheirourgia,' where 'kheir' meant 'hand' and 'ergon' meant 'work.'

'kheirourgia' transformed into the Old French word 'cirurgie,' and eventually became the modern English word 'surgery' through Middle English.

Initially, it meant 'hand work,' but over time it evolved into its current meaning of 'medical treatment involving operations.'
