Etymology
Origin of trader
Explanation
A trader is a person who either buys goods and resells them, like a merchant who runs a store or a person who buys and sells stocks and bonds. The original meaning of trader was "one engaged in commerce," meaning someone who makes a living buying things and selling them at a profit. Originally, traders would literally trade goods for other goods, while today most of them trade goods for money. Financial traders work solely with money, buying and selling currency, stocks, bonds, and funds.
