Fervid

Fervid is an adjective meaning intensely enthusiastic or passionate, often describing emotion, belief, or expression that is ardent and energetic. It can apply to zeal in advocacy, devotion to a cause, or vivid, impassioned prose or rhetoric. While it frequently conveys admiration for the speaker's commitment, it can also imply excessive or feverish intensity depending on context.

From Latin fervidus, from fervere “to boil,” the word historically suggests heat and boiling energy. It entered English in the early modern period and is common in literary and journalistic styles. The noun fervor is closely related, and the adverb fervidly exists.

Fervid is often used with positive connotations, as in fervid supporters or a fervid defense, but it can carry pejorative overtones when implying fanatical zeal or recklessness. Common collocations include fervid rhetoric, fervid prose, or fervid nationalism. Synonyms include ardent, zealous, vehement, and impassioned; antonyms include indifferent, apathetic, or cool.
