A more thorough explanation:

Definition: Solvendum in futuro (sol-ven-dum in f[y]oo-t[y]oor-oh) is a Latin term that means "to be paid in the future." It refers to a debt that is currently due but can be paid at a later date.

Example: Let's say you borrowed $100 from a friend and promised to pay it back in a month. The debt is solvendum in futuro because it is due now but payable in the future.

Explanation: The example illustrates the definition of solvendum in futuro because the debt is currently due, but the payment is not expected until a later date. This means that the debt is not considered fully paid until the future payment is made.
