'adenopathy' originates from Greek, specifically the word 'adēn,' where 'adēn' meant 'gland' and 'pathos' meant 'suffering or disease.'

'adēn' transformed into the French word 'adénopathie,' and eventually became the modern English word 'adenopathy' through medical Latin.

Initially, it meant 'disease of the glands,' and this meaning has largely remained the same in modern usage.
