Etymology

It is inherited from Latin mercātus (“trade; market, fair”), written Old Galician-Portuguese mercado in the oldest texts.[2][3][1][4] The Latin noun is formed on mercor (“to trade, deal”) with the action-noun suffix -tus.[5][1] Houaiss explains it from the supine.[2] In the medieval language it coincided in form with the past participle of mercar “to buy”, and Silva Bastos still treats it as that participle.[1][6]

The same Latin word is Galician mercado, Spanish mercado, Catalan mercat, Occitan mercat, French marché and Italian mercato.[7][1]

The verb belongs with merx (“goods, merchandise”), from Proto-Italic *merk- (“trade, exchange”), a family that also includes mercēs (“payment”) and the god's name Mercurius.[8] De Vaan derives the root from a word of the economy that he takes to be of Etruscan origin, while Nikolaev and Matasović have proposed Indo-European etymologies.[1][8]

Earliest recorded meaning

Latin charters of Portugal use the word from the 12th century: in mercado aut in ecclesia in 1162 and in concilio aut in mercado uel in ecclesia in 1185.[4] The first vernacular record in the DDGM is from 1262, en concello ou en mercado ou en egleia “in the council or in the market or in the church”, where it means the place of public trade.[4] The Cantigas de Santa Maria have Irey cras a mercado “I'll go to market tomorrow”.[4]

Semantic evolution

In the cantigas d'escarnho the word also meant a deal or bargain: de gran mercado was “very cheap” and mal mercado “a bad deal, dear”.[4][9] Morais (1813) still records bom mercado “a good price, cheap” beside the sense “fair, market square”.[10] Viterbo defines it as a place set aside for buying and selling on a certain day, like a feira.[11]

The old Caldas Aulete adds the covered market building and a city that is a great centre of trade, as London.[12] In economics it came to mean the system of supply and demand, the body of consumers of a product and the trade of a country or between countries, with many compounds (mercado de capitais, mercado negro, mercado de trabalho).[2][1] Hunsrik, the German dialect of southern Brazil, borrowed it as Mërkaat.[1]
