vendedor
/bendeˈdoɾ/ · B1 · noun · m
salesman
🛒 vender (to sell) + -dor (one who does) = seller; like English vendor
From Latin vendere, to sell, the same root as English vendor and vending machine. The Spanish suffix -dor works like English -er: trabajador is a worker, comprador is a buyer, and vendedor is a seller.
