Shilling. This word is supposed by some to be derived from the Latin - silicas, which signifies a quarter of an ounce, or the forty-eighth part of a Roman pound. At the tune of the Conquest, the shilling was worth four pence. Afterwards, the French solidus of twelve-pence was called by the name of shilling, and the Saxon shilling of fourpence took the name of groat, ox great coin, because it was the largest English coin then known.
