Forms

mercar (first-person singular present merco, first-person singular preterite merquei, past participle mercado)[1]

Etymology

It is inherited from Vulgar Latin *mercō (“to trade, buy”), an active form that replaced the deponent verb Latin mercor (“to trade, buy”).[2][3][4][1] The OLD cites the active form from a papyrus.[5] The Latin verb is formed from merx (“goods, merchandise”).[5][1]

The same verb is Galician mercar, Spanish mercar, Catalan mercar and Italian mercare.[6][1][7]

De Vaan relates the Latin noun to the name of the god Mercurius and supposes that both come from an Etruscan word of trade.[8][1] Wiktionary reports that Nikolaev and Matasović have since proposed Indo-European etymologies.[1]

Earliest recorded meaning

Lorenzo cites a Latin charter of 1095 with uolens mercari “wishing to trade” and gives Machado's date of 1124.[9] The Cantigas de Santa Maria have Ben mercamos “we have made a good bargain” and nas feiras u mercava “at the fairs where he traded”, and a cantiga d'escarnho of Johan Airas says of a man dizen que mercou atan mal “they say he bargained so badly”.[9][10] The Crónica Troiana has nõ podemos mellor mercar ca en conprar nosas uidas “we can make no better bargain than to buy our lives”.[9]

Semantic evolution

Viterbo explains that in the old language the verb meant not only buying but also contracting and exchanging, any lawful trade, citing an instrument of 1306, and that mercar mui mal meant to act rashly.[11] Camões used it figuratively in the Lusíadas: Que com trabalhos glória eterna merque “who with labours may win eternal glory”.[12][13]

Bluteau (1712–1728) calls mercar a provincial word for comprar and says he often heard courtiers condemn it.[14] In the dialects of Portugal it still simply means “to buy”, with a variant marcar.[15] In Bahia it means to cry one's wares in the street.[2][16]
