dissolute

The word dissolute originates from the Latin dissolutus, the past participle of dissolvere, meaning "to loosen apart" or "dissolve." This Latin term is itself a compound of the prefix dis- (apart) and solvere (to loosen, release). The literal sense of being "loosened apart" evolved metaphorically to describe someone whose morals or self-restraint are "loosened" or "dissolved," leading to a life of indulgence and laxity. By the late Middle English period, it had solidified into its modern abstract meaning, characterizing a person who is morally unrestrained and devoted to sensual pleasures.
