Forms
cacio m (plural caci)[1] Old forms include Old Italian cascio, caso, caxo and casciu.[2][3] Cascio was used by writers until the 16th century.[4][5]
Etymology
It is inherited from Latin cāseus (“cheese”).[6][7][8][1]
The Latin word lives on in Spanish queso, Portuguese queijo, Sardinian casu and Romanian caș, and in Dalmatian kis.[7][9][3] In France and Catalonia it was replaced by Medieval Latin formaticum, whence formaggio.[3] Early on it was borrowed into Germanic and Celtic: Old High German chāsi, German Käse, Old English cēse, English cheese and Old Irish cáise.[7][9]
The origin of the Latin word is uncertain.[6][10] It has often been traced to Proto-Indo-European *kwath₂- (“to boil, ferment”) and compared with the Slavic words for “leaven” and “sour milk”, but a /w/ should not have disappeared in Latin, and de Vaan finds no proposal free of weak assumptions.[7][10][1] A loan from a neighbouring Italic language such as Sabine has also been suggested.[1]
Earliest recorded meaning
The first record is the Venetian form caso in a document of the third quarter of the 12th century, the Ricordacione Cornaro.[2][3] In Tuscany cascio is in the Pisan account books of 1299 and cacio in Domenico Cavalca, before 1342; the sense throughout is “cheese”.[6][8]
Semantic evolution
Old Italian had many phrases with the word: cacio parmigiano, cacio di marzo, bestia da cacio for a sheep or goat kept for cheese, and sayings such as mangiare cacio e pane “to live frugally” and mettere le zanne nel cacio “to act greedily”.[2] Boccaccio has come il pane e 'l cacio in the Decameron.[11][12]
The word belongs to Tuscany and central and southern Italy, while the north uses formaggio.[6] Treccani notes that it is popular in Tuscany and Umbria and sounds literary in the north.[13] In the 19th century Tommaseo distinguished cacio as the general word from formaggio, the cheese as shaped in its mould.[12]
Derivatives include caciola (14th century), caciotta (1846) and caciocavallo, a southern hard cheese that reached the written language in the 14th century; why it is named after a horse is unclear, and one explanation is that the cheeses are hung in pairs astride a pole.[6][7]
