A person who denounces or formally accuses another person, especially of a crime or wrongdoing to authorities.
From Latin 'denuntians,' the present participle of 'denuntiare' (to announce against, denounce). The '-ant' suffix marks this as an agent noun describing someone who performs the action.
The Spanish Inquisition had official 'denunciantes'—this word documents one of history's darkest bureaucratic systems where accusation became a formal administrative position with real institutional power.
