The ri sign has the following uses in the Epic of Gilgamesh:
The specific usage numbers for the sign's meaning in the Epic is as follows: dal-, re-, ri-, tal-, ṭal-, RI-.
In the Amarna letters, ri also has a special usage when coupled with the naming of the Pharaoh, as "LUGAL-Ri". Lugal is the Sumerogram translated in the Akkadian language to 'King', Sarru. Thus in the Amarna letters, Lugal is used as a stand-alone, but sometimes supplemented with Ri, and specifically used as Sumerogram SÀR to be combined with RI to make sarru for king.
