A more thorough explanation:

Exigible (ek-sə-jə-bəl), adj. means something that is requirable or demandable, especially in the context of a debt. It refers to something that must be paid or fulfilled.

• Payment of rent is exigible on the first of every month.
• The loan is exigible in full by the end of the year.
• He owed a debt that was exigible immediately.

These examples illustrate how exigible is used to describe something that is required or demanded, especially in the context of a debt. In each example, there is an obligation that must be fulfilled, and failure to do so could result in consequences such as eviction, default, or legal action.
