Etymology

illicit = il<not> + licit<lawful>

  • il<not>: A variant of the prefix "in-" (from Latin), meaning "not," assimilated to "il-" before words starting with "l."
  • licit<lawful>: From Latin licitus (past participle of licēre, "to be allowed"), meaning "permitted by law."

Etymology Origin:
"Illicit" entered English in the early 16th century from Latin illicitus ("not allowed"), combining the negative prefix il- with licitus ("lawful"). The root licēre also gives rise to "license" (permission) and "licit" (lawful, though rare). The word's evolution reflects a clear dichotomy between legality ("licit") and prohibition ("illicit"), emphasizing societal or legal boundaries.
