Cuneiform law
Cuneiform law refers to any of the legal codes written in cuneiform script, that were developed and used throughout the ancient Middle East among the Sumerians, Babylonians, Assyrians, Elamites, Hurrians, Kassites, and Hittites. The Code of Hammurabi is the most well-known of the cuneiform laws, but there were a number of precursor laws.
U (cuneiform)
The cuneiform U sign, is found in both the 14th century BC Amarna letters and the "Epic of Gilgamesh". It can be used for the alphabetic "u", instead of the more common 2nd u, (ú). It has two other uses, commonly. It can be used for the number 10 (especially the Amarna letters from Tushratta of Mitanni, or Burna-Buriash II the king of Babylon), but its probable greater use is for the conjunction, "u", with any of the conjunction meanings: "and", "but", "else", etc.
