A dull, gloomy state of the mind; sadness; melancholy; low spirits or a mild depression; despondency; ill humor; now used only in the plural. "March slowly on in solemn dump." "Doleful dumps the mind oppress." "I was musing in the midst of my dumps." Note: The ludicrous associations now attached to this word did not originally belong to it. "Holland's translation of Livy represents the Romans as being in the dumps' after the battle of Cannae."
