Etymology

The word "feverish" combines "fever," derived from Old English fēfor (via Latin febris), meaning an abnormally high body temperature, with the suffix "-ish," from Old English -isc, used to form adjectives indicating possession of a quality. Over time, "feverish" expanded beyond its literal medical sense to describe heightened states of agitation or excitement, metaphorically linking physical heat to emotional intensity.
