/kəˈlætərəl sɪˈkjʊrəti/ – Phrase
Definition: sự đảm bảo thêm.
A more thorough explanation: Collateral security refers to an asset or property that a borrower pledges to a lender as a guarantee for repayment of a loan. If the borrower fails to repay the loan, the lender has the right to seize and sell the collateral to recover the outstanding debt.
Example: The borrower provided the lender with his car as collateral security for the loan.
