Denunciator

Denunciator is a noun describing a person who denounces or reports wrongdoing to an authority. The term carries a formal connotation and is most often found in historical, legal, or literary contexts rather than everyday speech.

Origin and form: Denunciator comes from Latin denuntiare, meaning “to announce publicly,” via Old French denunciateur, with the suffix -ator indicating a person who performs an action. In English, the word appeared in the early modern period but is now rare outside specialized or historical writing. In many cases, writers simply use a phrase like “one who denounces” rather than the single noun.

Usage notes: In historical texts, a denunciator might be described as someone who informs against a person to a court or government or who publicly exposes alleged wrongdoing. In contemporary English, more common terms conveying a similar role include informant, whistleblower, accuser, or reporter. Because denunciation as a practice has many modern-contemporary equivalents, denunciator is seldom used in current legal, journalistic, or everyday language, and when it appears it is usually for stylistic or historical effect.
