Etymology

It is borrowed from Ancient Greek εὐνοῦχος (eunoûkhos, “eunuch”).[2][1][3] Etymonline explains the Greek as “guard of the bedchamber”, from εὐνή (eunḗ, “bed”) and ἔχω (ékhō, “to have, hold”), and Donatus already gave this explanation.[4][5]

Earliest recorded meaning

Terence uses it in the Eunuch, a comedy whose title is feminine because fabula is understood.[6][7] Köbler dates Terence 190–159 BC.[8]

Semantic evolution

It meant a castrated man, in Cicero, Caesar, Martial and Juvenal.[7][6] The Vulgate uses it often, and medieval writers referred to the eunuchs of Matthew 19 and the Ethiopian eunuch of Acts 8.[7][9]

In medieval Latin it also meant a chamberlain, an official or servant, and of animals a gelding.[8][10][9] English eunuch is recorded in the late 14th century.[4]
