💰 Same root as fiancé: from fiar, to trust. A fianza is money pledged on trust
Spanish fiar (to trust, to vouch for) comes from Latin fidere, the root of fidelity, confide and the French fiancé. A fianza is your promise backed by cash: bail for a court, or the deposit a landlord keeps until you return the keys.
