Etymology

The weight is inherited from Vulgar Latin *pēsum, from Latin pēnsum, which in Latin meant the quantity of wool weighed out to a slave woman to spin in a day.[1][2][3] “Pēnsum” is the neuter of pensus (“weighed”), the past participle of pendō (“to weigh”), used as a noun.[2][3][4] The ⟨n⟩ before ⟨s⟩ was weakened and lost, as the Romance forms show.[5][6] The word is pan-Romance: Old French pois (modern French poids), Occitan pes, Catalan pes, Spanish peso, Portuguese peso, Sardinian pesu, Friulian pes, Romansh pais and Romanian păs, which means “grief”.[3][6] DÉRom reconstructs a Proto-Romance neuter noun */ˈpes-u/, with plurals in “-ora” and “-a”, from every branch except Dalmatian.[7] In Sardinian, southeastern French, eastern Occitan and Spanish the word also means “a pair of scales”.[6]

Latin “pendō” meant “to hang (something)”, then “to weigh out” and “to pay”.[8] Most handbooks take it as a variant of the root Proto-Indo-European *(s)penh₁- (“to spin”), through “stretch a thread” and “leave hanging”.[8] De Vaan finds this possible but not obvious, and also considers a nasal present of Proto-Indo-European *ped- (“to fall”).[8]

Earliest recorded meaning

GRADIT dates the word to 1279.[9] DELI's first records are from the late 13th century: Monte Andrea uses it for a very heavy body, Bono Giamboni (before 1292) for the force that draws bodies towards the earth, and the Novellino (late 13th century) for what weighs on the mind.[2] Giamboni's text describes an ice sheet that broke under “the very great weight” of the crowd and the animals crossing it.[10][11]

Semantic evolution

Dante (before 1321) uses peso for the weight used on a scale, and Boccaccio (1353) for authority and importance, the sense of dare peso “to give weight” and di poco peso “of little account”.[2] The figurative sense of a burden or worry, also old, gave togliersi un peso dallo stomaco “to take a weight off one's stomach”.[9] Trade gave peso lordo and peso netto (gross and net weight) and a peso d'oro “at the price of gold”.[12][13][9]

Sport added new senses in the 20th century: the weight categories of boxers and wrestlers (1914), and the iron ball of the shot put (1935).[2] Pesi massimi, pesi medi and peso piuma are calques of English heavy-weights (1857), middle-weights and feather-weight (1889). Peso massimo has lately also come to mean a leading political figure, like French poids lourd.[2] The sportsman who lifts weights or throws the shot is a pesista (1942).[2][3]

Pronunciation

Forms

peso m (plural pesos)[1]

Etymology

The currency is borrowed from Spanish peso, which properly means “weight”, the same word as Italian peso1.[2][3][9][1] The Spanish word is recorded from 962 and comes from Latin pēnsum.[9][15]

Earliest recorded meaning

The first record is in Antonio Pigafetta's account of Magellan's voyage (about 1525), where islanders give pesi de oro, gold pesos, for iron, and a peso is said to be worth about a ducat and a half.[2][10] GRADIT dates the word to 1533.[9]

Semantic evolution

In the 16th century the peso was a Spanish weight and coin of gold or silver, mentioned by Ramusio and in Venetian reports.[10] Today it is the name of the currency of several Spanish-speaking countries, chiefly in Latin America, and of the Philippines.[9][14][15] Its diminutive peseta was taken into Italian in the 16th century.[3]

Timeline

  • 962 – Spanish peso is first recorded.[9]
  • About 1525 – Pigafetta writes of pesi de oro.[2][10]
  • 1533 – GRADIT's date of first record.[9]
  • 16th century – Peseta is taken from Spanish.[3]

Meanings

Noun

  1. peso: the name of the currency of several Spanish-speaking countries, mostly in Latin America, and of the Philippines: peso messicano, peso argentino.[9][14][15]
  2. (historical) An old Spanish coin and unit of weight for gold.[10]

Word family

  • peseta
  • pesare
  • penso
  • pesante
  • Latin pensum
  • Spanish peso

Usage notes

The currency is pronounced with an open ⟨e⟩, /ˈpɛ.zo/, and its plural is pesos or invariable.[1][15] In Tuscany peso is also an adjective meaning “heavy” and, figuratively, “tiresome”, formed from pesare and recorded since before 1449; in Collodi's Pinocchio the puppet asks the tuna fish Siamo troppo pesi? “are we too heavy?”.[9][5][10] Old Tuscan peso “pea” (14th century) is a different word, from Latin pisum.[16][10] In the wool trade peso was also the quantity of wool handed out to the wool-beaters (1688), a direct survival of the Latin sense.[16]
