Etymology: The caldarium was the hottest room in a Roman bath complex, a heated chamber where bathers sweated before plunging into cooler water. Its name comes straight from Latin "caldarium," a noun built from the adjective "caldarius," meaning "pertaining to bathing" or "suitable for bathing," and that adjective in turn rests on "caldus," "warm, hot." The root behind "caldus" is the Latin verb "calere," "to be warm," which is also the source of the English word "calorie" through a different route. The Latin word is "caldarium" itself, with the "-arius" suffix attaching a sense of place or purpose, so the bathing room was named for its warmth rather than for anything like water or cleaning. English took the term over unchanged, using it for the hot room of the Roman bathhouse and, in modern usage, for the matching room in reconstructed or historical baths.
