Pronunciation

Forms

peso m (plural pesos)[3] It was first francized as peze (1598).[1][4] The reformed spelling is péso.[5][6]

Etymology

It is borrowed from Spanish peso (“weight”), the name of a monetary unit, recorded in Spanish as pezo in 1672 and in its present form in 1681.[1][4] The Spanish word properly means “weight” (of gold) and goes back to Latin pensum (“weight”),[1][4][7] like French poids.[4]

Earliest recorded meaning

It is first found, as peze, in 1598 in R. Regnault's translation of J. Acosta's Spanish Histoire naturelle et moralle des Indes.[1][4] The Dictionnaire de Trévoux records it again in 1752 as a money of account of Spain.[1]

Semantic evolution

After the isolated record of 1598 the word came back in 1752;[1][4] the Grand Robert and Petit Robert date it from 1839, with an isolated record in a translation of 1787,[7][2] and the GLLF from the Larousse of 1875.[8][9] Larousse gives it two senses: a gold coin struck in Spain from the 15th century, worth eight reals, and the main monetary unit of several Latin American countries and of the Philippines.[5]

The Spanish diminutive peseta, the Spanish unit of currency, was borrowed in 1787 as pesetta and was used familiarly for “money” from 1903 until about 1950.[4]
