Etymology: "Hyperpyrexias" is simply the plural of "hyperpyrexia," a medical term for a body temperature far above normal. Its two halves are both Greek. "Hyper-" comes from ancient Greek "hupér," meaning "over" or "beyond," which English has borrowed for countless words describing excess. "Pyrexia" comes from Greek "pyressein," meaning "to be feverish," from "pyr," meaning "fire." Medical writers used "pyrexia" for fever, so "hyperpyrexia" literally names a fever that has gone beyond the ordinary. The compound is a modern coinage built by combining these existing parts, a common method in medical vocabulary. Its meaning is transparent: the prefix intensifies the sense of the base word. Because the term describes a condition in the body rather than a figure of speech, it has stayed largely technical, used by clinicians rather than the general public.
