Dungeon - Etymology

Etymology

The word dungeon comes from Old French donjon (also spelt dongon), which in its earliest usage, meant "a keep, the main tower of a castle which formed the final defensive position to which the garrison could retreat when outer fortifications were overcome". The first recorded instance of the word in English near the beginning of the 14th century also meant "an underground prison cell beneath the castle keep". While some sources cite Medieval Latin dom(i)niōn- "property" (and ultimately dominus "lord") as the original source, it is more likely that the word derives from the Frankish *dungjo, *dungjon- ("dungeon, vault, bower"), from Proto-Germanic *dungijōn, *dungō ("an enclosed space, treasury, vault"), from Proto-Indo-European *dʰengʰ- ("to cover, hide, conceal"), related to Old Saxon dung ("underground vault, cellar"), Old High German tung ("a cellar, underground living quarter"), Old English dung ("a dungeon, prison"), and Old Norse dyngja ("a detached apartment, lady's bower"). In English, a dungeon now usually only signifies the sense of underground prison or oubliette, typically in a basement of a castle, whereas the alternate spelling donjon is generally reserved for the original meaning.

In French the term donjon still refers to a "keep", and the term oubliette is a more appropriate translation of English "dungeon". Donjon is therefore a false friend to "dungeon" (for instance, the game "Dungeons and Dragons" is titled "Donjons et Dragons" in its French editions).

An oubliette (from the French oubliette, literally "forgotten place") was a form of dungeon which was accessible only from a hatch in a high ceiling. The word comes from the same root as the French oublier, "to forget", as it was used for those prisoners the captors wished to forget.

The earliest use of oubliette in French dates back to 1374, but its earliest adoption in English is Walter Scott's Ivanhoe in 1819: 'The place was utterly dark—the oubliette, as I suppose, of their accursed convent.' There is no reason to suspect that this particular place of incarceration was more than a flight of romantic elaboration on existing unpleasant places of confinement described during the Gothic Revival period.
