Bond

is a loan you make to a government or corporation. In exchange, they promise to pay you interest (coupon) regularly and return your principal at maturity.

Bonds are called 'fixed income' because they pay a fixed interest rate. They're generally less risky than stocks but offer lower returns.

Quick answer

A bond = you loan money to a company or government. They pay you interest regularly and return your principal at maturity. Bonds are safer than stocks but offer lower returns. Bond prices fall when interest rates rise.

A bond is a loan to a government or company that pays periodic interest and returns principal at maturity; its price moves inversely to interest rates.
