Chapel is ultimately derived from the Late Latin word cappa, meaning "cloak." How did we get from a garment to a building? The answer to this question has to do with a shrine created to hold the sacred cloak of St. Martin of Tours. In Medieval Latin, this shrine was called cappella (from a diminutive of cappa, meaning "short cloak or cape") in reference to the relic it contained. Later, the meaning of cappella broadened to include any building that housed a sacred relic, and eventually to a place of worship. Anglo-French picked up the term as chapele, which in turn passed into English as chapel in the 13th century. In case you are wondering, the term a cappella, meaning "without instrumental accompaniment," entered English from Italian, where it literally means "in chapel style."
