Word History of ACE

An Old French word referring to the side of a dice with one spot came from a Latin word as, the name of a small coin, perhaps because a throw of one in a gambling game was only worth a single as. The English word ace was borrowed from the Old French word. Later, ace was extended in meaning from the side of a dice with one spot to a playing card with a single mark. Other meanings have come from this sense.
