    The issuer receives it.

    ■ Essence
    A bond is a financial instrument for lending money.

    Answer: It means lending money to a government or company.

    Types include:

    A financial relationship is created.

    ■ Essence

    How Do Investors Earn Money From Bonds?

    Answer: Through interest and price changes.

    Two return sources:

    👉 Interest → regular payments

    Interest is scheduled.

    Price depends on market conditions.

    ■ Essence
    Bond returns come from income and market price.

    What Is Maturity?

    Answer: It is the date when the principal is repaid.

    Bonds have a fixed term.

    At maturity:

    👉 Principal is returned

    Examples:

    👉 10 years

    Time defines the contract.

    ■ Essence
    Maturity determines when the original investment is returned.

    ■ Essence
    The difference lies in who receives the loan.

    ■ Essence
    Bond safety is relative, not absolute.
