castagna

Forms

castagna f (plural castagne)^[1] Old forms include Old Italian castegna, castangna and castagnia.^[2]

Etymology

It is inherited from Latin castanea (“chestnut; chestnut tree”).^[3][4][5][1] The Latin word is from Ancient Greek καστάνεια (kastáneia), an adjective formed from κάστανον (kástanon, “chestnut tree”).^[4][1] Latin first used it with nux (“nut”), translating the Greek phrase for the chestnut, and the fruit came to the West with the Greek colonies of Asia Minor.^[6] The Greek word is probably pre-Indo-European.^[3] Nocentini traces it to the Near East, and DEI calls it a Mediterranean relic, comparing the Armenian words for the chestnut and its tree.^[4][7] Isidore of Seville explained the name by the paired fruits, which sit in their husk like testicles and are as if castrated when taken out.^[8]

The word is pan-Romance: French châtaigne, Occitan castanha, Catalan castanya, Spanish castaña, Portuguese castanha, Sardinian castanza and Romanian castană.^[4][9][10] Meyer-Lübke and DÉRom also reconstruct a variant *castinea with a short /ɪ/, which is continued in Ladin and Friulian and is typical of northern Italian.^[9][11] Latin ⟨-nea⟩ became Italian ⟨-gna⟩. castagneto was remade on the noun, since Latin castanetum would have given a form in ⟨-néto⟩.^[3]

Earliest recorded meaning

The first record in the TLIO is a Pistoian document of about 1200, with the sense “the fruit of the chestnut tree”.^[2] Old Italian also used the word for chestnut flour, for a tiny quantity, and for the tree itself, as Latin castanea named both fruit and tree.^[2][4]

Semantic evolution

DELI's first records of the fruit are a statute of 1310–1313 and Cenne da la Chitarra, before 1336.^[3] Castagno took over the tree: it is recorded for the wood in 1284 and for the tree in Boccaccio in 1353.^[3]

From the 19th century the word also named the horny patch on the inner side of a horse's leg (1820), and in slang a violent punch, and in sport a very powerful blow or shot.^[3][5][12] In seamanship it is the pawl that stops a capstan from turning back.^{[5][13][13][5]} Several plants take their name from it: castagna d'acqua is the water chestnut, and castagna d'India or castagna cavallina the horse chestnut.^[14][5][7]

The castanets, castagnette (1623, Marino), come from Spanish castañetas (1571), a diminutive of castaña.^[3] Like castagnola “firecracker”, they are named from the crack of chestnuts bursting in the embers.^[3] Castagnaccio, a flat cake of chestnut flour, is recorded before 1449 in Burchiello according to DELI, before 1322 according to Nocentini.^[3][4] English records castagna in 1817.^[15]
