'adenectomy' originates from Greek, specifically the word 'aden' meaning 'gland' and 'ektomē' meaning 'excision'.

'aden' and 'ektomē' combined in Greek to form 'adenektomia', which evolved into the modern English word 'adenectomy'.

Initially, it meant 'excision of a gland', and this meaning has largely remained the same in modern usage.
