castagno

Forms

castagno m (plural castagni)^[1]

Etymology

The LEI takes it as inherited from Vulgar Latin *castaneum: beside Latin castanea (“chestnut”) for the fruit, Latin formed the tree name castaneus, recorded in Gregory of Tours in the 6th century, after the model of fruit-tree names.^[2] The Romance languages continue a neuter form as a masculine, as with pirus (“pear tree”) and pirum (“pear”), and the same word is Old Occitan castanh, Old Spanish castaño (1210) and Portuguese castanho (1456).^[2]

In GRADIT, Devoto–Oli, Sabatini–Coletti, Zingarelli and Treccani it is from Italian castagna, an Italian formation.^{[3][4][5][6][7]} Wiktionary allows both.^[1] DELI and Nocentini give it under the fruit's name.^[8][9]

The Latin word for the chestnut comes from Ancient Greek καστάνεια (kastáneia), an adjective of κάστανον (kástanon, “chestnut tree”), which came from the Near East.^[9][1] DELI thinks the Greek word is probably pre-Indo-European.^[8]

Earliest recorded meaning

DELI's first record is from Florentine texts of 1284, for the wood of the tree.^[8] The TLIO and Nocentini date the first record to a Florentine document of 1287, and the LEI cites Florentine chastangno in 1288 and an Old Veronese form from the 13th century.^[10][9][2]

Semantic evolution

Old Italian already used the word both for the tree and for its timber, as in Sienese legni di castagno (1309–1310).^[10][2] Boccaccio's Decameron has the tree in a landscape tra ulivi e nocciuoli e castagni (“among olives, hazels and chestnuts”), and the Crescenzi translation says that the tree is well known and comes in two kinds, cultivated and wild.^[11][8]

Tommaseo describes it as a tree of the first economic importance: its wood lasts in damp and in water, its nuts fed mountain people for much of the year, and its leaves were gathered for bedding for animals.^[12] An adjective castagno “chestnut-coloured” is recorded from the 16th century, and castagno d'India, the horse chestnut, from the 19th.^[13]
