Forbidden by law, rules, or custom; unlawful.

Illicit describes something that is not permitted, often implying a moral or ethical wrong in addition to being illegal. It suggests something clandestine or underhanded.

The story behind the word. The word 'illicit' comes from the Latin 'illicitus,' which means 'not allowed' or 'unlawful.' This is formed by combining the negative prefix 'in-' (which becomes 'il-' before 'l') with 'licitus,' meaning 'allowed' or 'lawful.' 'Licitus' itself comes from 'licere,' meaning 'to be permitted.' So, 'illicit' literally means 'not permitted,' perfectly conveying the sense of something forbidden by law or custom.
