[From orgies, secret rites, from Old French, from Latin orgia, from Greek; see werg- in Indo-European roots.]
Word History: The word orgy has become connected in the minds of many of us with unrestrained sexual activity, but its origins are much less licentious. We can trace the word as far back as the Indo-European root *werg-, meaning "to do," also the source of our word work. Greek orgia, "secret rites, worship," comes from *worg-, one form of this root. The Greek word was used with reference to the rites practiced in the worship of various deities, such as Orpheus and Dionysus. The word in Greek did not denote sexual activity, although this was a part of some rites. The rites of Dionysus, for example, included only music, dancing, drinking, and the eating of animal sacrifices. Having passed through Latin and Old French into English, the word orgy is first recorded in English with reference to the secret rites of the Greek and Roman religions in 1589. It is interesting to note that the word is first recorded with its modern sense in 18th-century English and perhaps in 17th-century French. Whether this speaks to a greater licentiousness in society or not must be left to the historian, but certainly the religious nature of the word has gone into eclipse.
1561, orgies (pl.) "secret rites in the worship of certain Gk. and Roman gods," especially Dionysus, from M.Fr. orgies (c.1500), from L. orgia, from Gk. orgia (pl.) "secret rites," from PIE base *werg- "to work" (see urge (v.)). The singular, orgy, was first used in Eng. 1665 for the extended sense of "any licentious revelry." OED says of the ancient rites that they were "celebrated with extravagant dancing, singing, drinking, etc.," which gives "etc." quite a workout.
