A more thorough explanation:

A debitor is a person who owes money or has a legal obligation to someone else. This term comes from Roman law.

For example, if you borrow money from a bank, you become a debitor to the bank. You have a legal obligation to pay back the money you borrowed, plus any interest or fees.

Another example is if you buy something on credit from a store. You become a debitor to the store, and you have a legal obligation to pay for the item you bought.

Overall, a debitor is someone who owes money or has a legal obligation to someone else. This can be for a variety of reasons, such as borrowing money, buying something on credit, or not paying a bill on time.
