orgy: [16] Orgy comes ultimately from Greek órgia (like English organ, a descendant of the Indo-European base *worg- ‘work’), which denoted ‘religious revels involving dancing, singing, getting drunk, and having sex’. It was a plural noun, and passed into English via Latin orgia and French orgies as orgies. This was very much a historical term, denoting the goings-on in ancient Greece, but in the 18th century it was singularized to orgy, and used for any ‘copulatory revelry’.
