licit

The word "licit" originates from the Latin past participle licitus, meaning "allowed" or "lawful," derived from the verb licēre, "to be permitted." This Latin root is itself traced back to the Proto-Indo-European base leik-, which carried the sense of "to offer, to bargain," a concept that evolved into the realm of what is socially and legally sanctioned. The direct adoption of licitus into English, with the adjectival suffix preserved, created a term specifically denoting conformity with law or accepted standards. Its modern usage often serves as the formal, technical antonym to "illicit," precisely retaining its ancestral link to the concept of permission.
