What does feverous mean?
Feverous is an adjective meaning suffering from, marked by, or resembling a fever — and, by extension, characterized by fever-like heat, restlessness, or excited agitation. It functions as a literary alternative to the much more common word "feverish," appearing most often in older or elevated prose: a feverous brow, a feverous night, a feverous tumult of the mind. The word carries connotations of bodily illness but also of emotional intensity, so it can describe both a sick patient burning with temperature and a crowd whipped into a state of frantic anticipation. Derived ultimately from the Latin root febris, meaning fever, it belongs to the same family as "febrile" and "febrifuge." Though rarely heard in modern conversation, feverous remains a vivid choice for writers seeking a slightly antique, evocative register, and understanding it makes classic literature easier to read.

Before "feverish" took over, English speakers reached for "feverous" — a word Shakespeare's era knew well, now preserved mainly on the pages of classic literature.

Etymology of feverous
Feverous derives from the noun "fever," which entered Middle English from Old French fievre, itself from Latin febris, meaning fever. The adjective form developed in English by way of Old French fievereux, following the common -ous suffix pattern for forming adjectives from nouns. It shares its Latin root with medical terms such as "febrile" (feverish) and "febrifuge" (a substance that reduces fever).
