soldo m (plural soldi)[1]

Etymology

It is inherited from Late Latin soldus, the shortened form of Latin solidus (“solid, massive”) used as a noun, with nummus (“coin”) understood: a coin of solid gold.[2][3][4][1][5] Nocentini adds that the solidus was a gold coin of stable value put into circulation by Constantine in the 4th century.[3][6] The same word is French sou, Occitan sol, Catalan sou, Spanish sueldo and Portuguese soldo, and Sardinian soddu in Logudorese.[3][7]

De Vaan derives the Latin adjective from the root of Latin salvus (“whole, safe”) and sollus (“whole”), Proto-Indo-European *solh₂- (“whole”), and finds a link with soleō (“to be accustomed”) unlikely.[8][1] Wiktionary makes the Italian word a doublet of solido and sodo, and probably of saldo.[1]

Earliest recorded meaning

Medieval Latin soldus is recorded at Cavarzere in 1183, and a man called Wilinzone Cento Soldi appears in a Medieval Latin document of Chioggia in 1137.[2] The first Italian record is in the Breve di Montieri of 1219, for the coin worth twelve denari and a twentieth of the lira.[2][9]

Semantic evolution

In 1305–06 Giordano da Pisa uses soldo for the pay of a mercenary, the sense behind soldato “soldier”, and later writers use it for military service.[2][10][11] The coin changed value through the centuries, and in Italy the soldo was five centesimi, a twentieth of the lira, until the Second World War.[4][12]

The plural soldi came to mean money in general.[2][4] Its low value gave phrases such as da quattro soldi “cheap, worthless”, non valere un soldo and alto quanto un soldo di cacio “very short”.[4][13][12] French took solde “pay” (1430) from Italian, and English soldo for the Italian coin is recorded from 1596.[9]
