A more thorough explanation:

Definition:

Secured (adjective) - refers to a debt or obligation that is supported or backed by security or collateral.

Examples:

• A secured loan is a type of loan that requires the borrower to provide collateral, such as a car or house, to guarantee repayment.
• A secured credit card is a credit card that requires a cash deposit as collateral, which is used to secure the credit line.

Explanation: When a debt or obligation is secured, it means that the lender has some form of security or collateral to fall back on in case the borrower is unable to repay the loan. This reduces the risk for the lender and allows them to offer lower interest rates and better terms to the borrower. The examples provided illustrate how different types of loans and credit cards can be secured by collateral, which provides a level of protection for the lender.
