Cuneiform law
Cuneiform law is generally classified separately from later Middle Eastern law, but has been viewed as a predecessor of Biblical and Jewish law. The communities of the Middle East that made use of cuneiform law were generally all in contact with one another, and developed similar cultures. Akkadian, a cuneiform language, was used throughout the entire area, and even as far as Egypt, for diplomatic communications during the Amarna Period.
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.
