Etymology: The verb "affiance" begins with a promise rather than a marriage: its deepest root is the Latin "fidere," "to trust," the same source that gave English "faith," "fidelity," and "confide." Medieval Latin built "affidare" from it, meaning to pledge one's faith to someone, and that idea passed into Middle French as "affier," to betroth or bind by oath. Over time the French noun "affiance" came to name the solemn promise itself, and English borrowed both the verb and the noun from that French stock. The word's structure is easy to read once you see the layers. The core is "fid-," trust; the Latin prefix "ad-" added the sense of directing a pledge toward someone; and the "-ance" ending, from French, turns the action into a state or noun, which is why "affiance" can name the pledge as well as the act of making it. Each step kept the original idea of binding oneself to another through trust, which is why a betrothal, and not just a casual agreement, sits at the heart of the word.
