Pronunciation

Forms

illicite (plural illicites)[1]

Etymology

It is borrowed from Latin illicitus (“forbidden, unlawful”),[2][3][1] formed from in-, a negative prefix, and licitus (“permitted, lawful”), from the impersonal verb licet (“it is allowed”).[4][5] The Anglo-Norman illicite (“illegal”) is recorded in 1363–1364.[6] Rey notes that it is more common than licite itself because of its use in law.[7]

Earliest recorded meaning

It is first recorded in 1364 in a royal ordinance.[2][8] Littré quotes Jouer à jeux illicites “to play unlawful games” from the 14th-century Ménagier.[5]

Semantic evolution

The sense, forbidden by law or by morality, has stayed the same since the 14th century.[2][9] Calvin uses it in the 16th century of dishonest gains.[5] In law it describes what the law prohibits; in morals it is said of what is forbidden, as of an illicit love affair.[2]
