來源：
Middle English donjon [castle keep, dungeon]
中古英語 donjon [城堡主樓]
from Old French [keep]
源自 古法語 [城堡主樓]
probably from Medieval Latin domniô [the lord`s tower]
可能源自 中世紀拉丁語 domniô [領主的塔]
from Latin dominus [master] * see dem-
源自 拉丁語 dominus [主人] *參見 dem-

<注釋>The worddungeon may have gone down in the world quite literally, if one etymology of the word is correct. Dungeon may go back to a Vulgar Latin word,domniô, meaning .the lord`s tower,.which came from Latindominus, .master.. In Middle English,in which our word is first recorded in a work composed around the beginning of the 4th century,it meant .a fortress, castle,. and .the keep of a castle. as well as .a prison cell underneath the keep of the castle..Dungeon can still mean .keep,. although the usual spelling for this sense is donjon, but the meaning most usually associated with it is certainly not elevated.It is also possible thatdungeon goes back to a Germanic word related to our word dung. This assumed Germanic word would have meant .an underground house constructed of dung..If this etymology is correct, the worddungeon has ended up where it began.
單詞dungeon 的一種詞源是它以其字面意義流傳下來， 如果這個單詞其中的一種語源是正確的話。 Dungeon 可追溯到拉丁俗詞domnio， 意為.領主的塔.，這一拉丁俗詞又來自拉丁文dominus， 意為.主人.。 在中古英語時期，該詞首次記錄于作于4世紀初的一部作品，意為.要塞，城堡.，.城堡主樓.以及.城堡方樓下的地牢.。Dungeon 仍有城堡主樓的意思，但最常與之聯(lián)系在一起的這一拼法為 donjon， 但最常與之聯(lián)系在一起的這一意義顯然流傳不廣。Dungeon 還可能上溯到與之相聯(lián)系的日耳曼語詞 dung。 這一假設的日耳曼語詞可能曾意為.由糞建構的地下房屋.。假如這一詞源正確，dungeon 一詞結束于它起源的地方
