Beyond the definition
Licentious is the word for freedom taken past the point of permission — the life lived outside the rules, particularly regarding sexuality. Its root 'licence' reminds us that licentiousness is not freedom but excess.
Origin & history
Latin: licentia (freedom, licence). The same root as 'licence' — what is permitted. Licentious takes the permitted too far: more liberty than the rules intended, more freedom than convention can absorb.
