Middle English as, borrowed from Anglo-French, going back to Latin ass-, ās "copper money piece (at first a pound, but progressively reduced to a half-ounce), pound unit of weight, unit," of uncertain origin
Note: The word ās has been compared within Latin to asser "wooden beam, pole, post" (generalized from a plural asserēs, from a singular *assis?) and assis, axis (by hypercorrection?) "plank, board," though any relationship is far from certain. A loanword from Etruscan?

History for 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.
