Etymology: "Turpid" is an English adjective meaning thick with sediment, and it comes from Latin "turpis", meaning foul, ugly or shameful. The Latin root is far better known through its descendant "turpitude", the word for moral baseness, which shares that same source. The "-id" ending is the Latin suffix that English borrowed into words describing a quality or state, as in "lucid" or "limpid". Attaching it to the Latin base gave English a term that carries the sense of something murky or clouded. The word's original Latin meaning of foulness ties it to the sense of a liquid turned dirty and unpleasant.
