What does flagitious mean?
Flagitious is a formal adjective denoting the extreme end of moral wrongdoing: grossly wicked, criminal, and shamefully outrageous conduct or the people guilty of it. Derived from the Latin flagitium — a shameful act worthy of public censure — it entered English in the early seventeenth century and has retained an air of courtroom gravity ever since. Where words like 'flagrant' merely signal that something is blatant, 'flagitious' adds a judgment of deep villainy: it is applied to atrocities, corruption, and scandals that shock the public conscience. The word is now rare outside legal, historical, and literary prose, which gives it real rhetorical power when used deliberately. A writer who reaches for 'flagitious' signals not just disapproval but categorical condemnation — conduct so base that ordinary criticism is insufficient. Its derivatives include the adverb 'flagitiously' and the noun form 'flagitiousness'.
adjectiveFlagitious describes a person or their actions as grossly wicked, villainous, or shamefully criminal — morally outrageous in a flagrant, scandalous way.
- Describing deeds or persons guilty of grave, scandalous criminal wickedness — the dominant and essentially only modern sense.
"The tribunal condemned the general's flagitious campaign against unarmed civilians."
"The report detailed the dictator's flagitious plundering of the national treasury."
"In his closing address, the prosecutor denounced the fraud as flagitious, unworthy of any civilized society."
Flagitious comes straight from the Latin word for a scoundrel deserving of public branding — the ancient Romans literally flogged such criminals, and the word still carries that whiff of the pillory.

Where does flagitious come from?
Flagitious derives from the Latin flagitiosus, meaning shameful or disgraceful, itself formed from flagitium — an offence crying out for public censure, originally one punishable by flogging (flagrum, a whip). It passed into English in the early seventeenth century via scholarly and legal Latin. The same Latin root gives English the adjective 'flagrant', from flagrare-related senses of glaring wrongdoing.
