A more thorough explanation:

pensio

In Roman and civil law, pensio refers to a payment made for the use of something that belongs to someone else. This payment is similar to rent paid for the use of another person's property.

• When you rent an apartment, you pay a monthly pensio to the landlord for the right to live in the apartment.
• If you borrow money from a bank, you will have to pay back the amount you borrowed plus a pensio, which is the interest charged by the bank for the use of their money.

These examples illustrate how pensio is a payment made for the use of something that belongs to someone else. In the first example, the pensio is paid for the right to live in someone else's property. In the second example, the pensio is paid for the use of someone else's money.
