What is the Spanish term for "Deposit"?

The Spanish term for "Deposit" is most accurately represented by "Fianza." In financial and legal contexts, "fianza" often refers to a type of deposit, particularly a security deposit that guarantees the fulfillment of an obligation, such as a rental lease. It is commonly used in scenarios where a party places funds as assurance, which will typically be returned at the end of the contract or agreement if all conditions are met.

While "reserva" translates to "reserve" and can imply a form of holding or saving something (including money), it does not specifically refer to the concept of a deposit in the same legal or financial sense. The other options, "No disponible" meaning "not available" and "daño" meaning "damage," do not relate to deposits at all. Therefore, "Fianza" is the most suitable term in this context.
