Etymology

According to Houaiss it is inherited from Vulgar Latin *platta (“metal sheet”), the feminine of *plattus (“flat”) used as a noun in Medieval Latin for a sheet of metal; it replaced Latin argentum (“silver”).[2] It is written Old Galician-Portuguese prata from the 13th century.[2][3] The Portuguese and Spanish words narrowed the sense from a metal sheet to silver itself.[3][4] Machado and Nascentes, following Meyer-Lübke, take the word from the Old Occitan plata (“metal sheet”) instead.[2][3][5]

The same word is Galician prata and Spanish plata; prato and chato go back to the same Vulgar Latin adjective.[1][4] The Vulgar Latin adjective is traced to Ancient Greek πλατύς (platús, “broad, flat”).[6]

Earliest recorded meaning

Houaiss's first record is plata in 1136, after Machado.[2] The Cantigas de Santa Maria speak of our'e prata “gold and silver”, and the Crónica Troiana of the gold and silver robbed from a temple.[3]

Semantic evolution

In the medieval language prata is the metal and things made of it, often paired with ouro “gold”; the Miragres de Santiago have dineiros de prata “silver pennies”.[3] Morais (1789) lists prata lavrada “wrought silver, plate” and prata em barra “silver in bars”.[7] In Brazil it is an informal word for money and for one real.[2][1] Prata da casa “the house silver” means the resources one already has, and in football a player bred by the club.[2]
