Sense: noun/1

Trader is a broad term for anyone who buys and sells goods or financial assets for a living. A merchant typically owns or runs a shop that specialises in a particular type of goods, such as a wine merchant or coal merchant — the word carries a more traditional feel. A dealer tends to work with specific, often higher-value, categories like art, cars, or antiques, and may operate at a wholesale level. A vendor is usually the person selling directly to the public at a market, fair, or from a temporary stall. A retailer is a business, not necessarily a person, that sells goods to the final consumer in small quantities. The key difference is scope: trader covers the widest range of activities, while the other words each highlight a specific selling context. For example, a woman selling scarves at a weekend market is both a trader and a vendor, but calling her a merchant would sound old-fashioned, and calling her a retailer would feel too formal.

Trader comes from the noun 'trade' (a line of business or the activity of buying and selling) combined with the agent suffix '-er' (someone who does something). 'Trade' entered Middle English from Middle Low German 'trade', meaning a track or course, which later came to refer to a regular course of commerce. The word 'trader' first appeared in the 16th century to describe a person engaged in commerce.
