caldaia

Forms

caldaia f (plural caldaie)^[1] Old forms include Old Italian caldara, caldera, callare and caudara.^[2] The form caldara survives as an old and regional variant.^[3][4][5]

Etymology

It is inherited from Late Latin caldāria (“cooking pot, cauldron”), the feminine of the adjective Latin caldārius (“of heat”) used as a noun, from caldus (“hot”), the short form of calidus, itself formed from caleō (“to be warm”).^[6][7][1] The noun is already found in the Vulgate, and Pliny uses the adjective of the hot room of a bath.^[8][9]

The same word is French chaudière, Occitan caudera, Catalan caldira, Spanish caldera, Portuguese caldeira and Romanian căldare.^[7][10] The LEI distinguishes an older layer, in which the suffix -ārius gave ⟨-aro, -ara⟩ (the Romanian word and many central and southern Italian dialect forms), from a later one that restored the Latin ending (Friulian cialdère, Romansh caldèra, Old Occitan caudieira).^[8] The neuter caldārium lives on beside it in the masculine caldaio and in Spanish caldero.^[8][11]

In Tuscan the Latin suffix became ⟨-aio, -aia⟩.^[12][3] In the derivatives calderaio and calderone the unstressed /a/ before /r/ turned into /e/, as in the future parlerò.^[6]

Earliest recorded meaning

The TLIO's first record is in the Lombard poem of Pietro da Bescapè (1274), and DELI's in the 13th-century Libro dei sette savj, with the sense of a large round metal vessel set on the fire to boil something.^[2][6][7]

Semantic evolution

In Old Italian the word named any large metal pot for heating liquids, including the vats of tanners and dyers and a vessel walled in above a furnace, and also a metal pail for drawing water.^[2] Dante describes cooks who have their kitchen boys push the meat down into the middle of the caldaia with hooks (Inferno 21), and Marco Polo's Italian translator tells of water boiled in large iron caldaie to make salt.^[9]

The modern technical sense, an apparatus that heats water or turns it into steam under pressure, appears in a Milanese printed text of 1826 with the spelling caldaja.^[6] It now names the boiler of a central-heating system or a steam engine, and Treccani notes that for large plants generatore di vapore is preferred.^[4][11] The word also names the shell of a kettledrum.^[13]

The craftsman who made such vessels was the calderaio (Medieval Latin calderarius at Bobbio in 1191, Italian before 1388 in Antonio Pucci), and a large cauldron a calderone, recorded in Boccaccio in 1353.^[6]
