market: [12] The Latin word for ‘goods to be sold’ was merx (source of English commerce, merchant, and mercury). From it was derived the verb mercārī ‘buy’, and its past participle produced the noun mercātus ‘trade, market’. In Vulgar Latin this became *marcātus, which was adopted into early Middle English as market. The now seldom used synonym mart [15] comes from early modern Dutch mart, a variant of markt ‘market’. => commerce, mart, merchant, mercury
