Etymology: Monasteries once had a "calefactory," the one room where monks could warm their hands by a fire, and it shares its root with this word. Both come from the Latin verb "calefacere," meaning "to make warm," built from "calere" (to be warm) and "facere" (to make). The Latin participle "calefaciens" gave English the adjective, which physicians adopted as a technical term for agents that produce warmth in the body's tissues. The word belongs to a family of medical terms built on the same pattern of "make" plus a root meaning a quality. "Rubefacient," for instance, uses "ruber" (red) and describes substances that redden the skin, and English medical writers coined many such words from Latin and Greek parts as the vocabulary of pharmacology grew. "Calefacient" was formed in this scientific tradition, not inherited from ancient medicine, so its Latin elements are classical while its specialized sense belongs to later English medical usage.
