'adenoidectomy' originates from Greek, specifically the word 'adēn,' where 'adēn' meant 'gland.'

'adēn' transformed into the French word 'adénoïde,' and eventually became the modern English word 'adenoidectomy' through medical terminology.

Initially, it meant 'related to glands,' but over time it evolved into its current meaning of 'surgical removal of the adenoids.'
