Ultimate origin
Latin calidus

Forms

calidārius (feminine calidāria, neuter calidārium); first/second-declension adjective; also syncopated caldārius[1][2]

Etymology

It is from Latin calida (“hot water”) + -ārius, formed on the noun for hot water, the feminine of calidus (“hot”).[1][3] Georges derives it from the short form caldus, and VOLI from the verb caleō (“to be warm”).[2][4]

Earliest recorded meaning

Vitruvius uses it of the bronze vessel of hot water for the bath.[2][5]

Semantic evolution

It described what served for heat or hot water.[1][2] Pliny the Younger, describing his villa, sets the hot rooms of the bath beside the cold ones,[3][6] and inscriptions record a hot room of a gymnasium and a bronze pot for hot water.[3] Pliny the Elder calls one kind of copper caldārium because it could only be worked hot,[2][7] and Palladius has a cement for the walls of bathrooms.[2]

Used as nouns, the feminine and neuter named the hot room of a bath and the bath itself: Seneca and Celsus have the neuter,[7][6] the Historia Augusta the feminine.[2][3] Both also came to mean a cooking pot or cauldron, in the Vulgate's First Book of Kings, in the herbal of Pseudo-Apuleius and in Eucherius.[2][6]

The TLL traces Italian caldaia, French chaudière and Spanish caldera to it, perhaps through a phrase meaning a pot for hot water.[3] In Polish medieval Latin caldārium was a cauldron for brewing, for boiling brine and for the ordeal, and caldārius a coppersmith.[8]
