Where does the word "due" come from? It comes from Latin debere, passing through Old French before entering English (1300s).

Due’s story begins in Latin: debere meant “to owe.” The root of 'debt', 'debit' and 'duty'. By medieval, the word had taken hold in Old French as deu. Carried into French for something owed or expected. It reached English by 1300s as due. Settled as the English word for something owed or expected at a particular time. Today, due means owed or expected to arrive or be paid at a particular time.
