Etymology: Causalgia is a medical coinage, not an ancient word, and its roots are Greek. The first part comes from "kaustos" (from kaiein, "to burn"), meaning "burning heat," and the second from "algos," meaning "pain," the same root that gives us "neuralgia" and "nostalgia." Put together, the term describes a burning pain, and it was built in New Latin, the scientific Latin used by physicians and naturalists in early modern and modern Europe, rather than handed down from classical antiquity. The word's shape is misleading at first glance. Readers might spot "caus-" and assume it means "cause," as in "causal," but that is a coincidence of spelling. The "caus-" here has nothing to do with causation; it is the burning sense of the Greek root, so the word literally names a pain of burning. Its English use is confined to medicine, where it describes a severe, burning pain that persists after nerve injury.
