Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

[Middle English eunuk, from Latin eunūchus, from Greek eunoukhos : eunē, bed + -okhos, keeping (from ekhein, to keep; see segh- in the Appendix of Indo-European roots).]

eunuch·ism n.

Word History: Eunuch goes back to the Greek word eunoukhos, "a castrated male employed to serve the women in the women's quarters of a household and to act as chamberlain," and the Greek word is derived from eunē, "bed," and ekhein, "to hold, to keep." A eunuch is a "bed-keeper," so to speak. To avoid suspicion about the parentage of their children, upper-class men in many ancient societies would post eunuchs to guard and serve in the bedchambers of the women of their households. Nowadays, when the word eunuch is mentioned outside of discussions of history and ancient customs, it is mostly used metaphorically, in the sense "an ineffectual man." In ancient times, however, the eunuchs who served powerful people were often far from being ineffectual. Since they were privy to the personal lives of ruling families and had the opportunity to acquire politically and financially useful information, some eunuchs amassed enormous personal fortunes and rose to positions of great power and responsibility.
