Ni (cuneiform)
The cuneiform sign ni is a common-use sign of the Amarna letters, the Epic of Gilgamesh, and other cuneiform texts. It has a secondary sub-use in the Amarna letters for addressing the Pharaoh, from the vassal states of Canaan. The address to the Pharaoh is often 'King-Lord-Mine': LUGAL, EN-ia which has many varieties of expression. "LUGAL” is the Sumerian name (meaning “king”) for the cuneiform glyph read in the Akkadian language as "Šarru", translating as English "king", and EN is read in Akkadian as bēlu, for "Lord", (thus "King, Lord-Mine"). In some Amarna letters the sub-use of ni is lí, for spelling "bēlu", be-lí often  .
