Other forms: dipsomaniacs
A dipsomaniac is a drunkard or alcoholic: someone who drinks alcohol to excess.
Since dipsomania is a word for alcoholism, it makes sense that a dipsomaniac is an alcoholic. A dipsomaniac has a physical need for alcohol that goes beyond being thirsty: it’s an addiction. The dipsa root (meaning "thirst") turns up in a few other somewhat obscure words, such as adipsia(meaning "loss of thirst") and polydipsia (meaning "excessive thirst").
