furieux

Furieux is a French adjective meaning extremely angry, furious, or enraged. It can describe people who are in a state of intense anger as well as non-human phenomena that convey ferocity, such as a furieux vent (a furious wind) or un bruit furieux (a fierce noise). The feminine form is furieuse, and the plural forms are furieux for masculine and furieuses for feminine nouns. When used predicatively, it typically follows a subject: Il est furieux (He is furious).

Etymology and range: Furieux derives from Latin furiosus, meaning “full of fury,” itself linked to furor, rage. The word shares its root with related terms in French and other Romance languages that express extreme anger or ferocity. In modern usage, furieux can denote moral or physical intensity, not only human anger, and it can appear in both formal and colloquial contexts.

Usage notes: Furieux is commonly contrasted with calmer states using antonyms such as calme, posé, or serein. Synonyms include furibond, colérique, or rageur, though each carries subtle nuances. The adverbial form is furieusement, used to describe actions done with great anger or ferocity. The term also appears in literary and journalistic style to emphasize forcefulness.
