Sumerogram

This type of logogram characterized, to a greater or lesser extent, every adaptation of the original Mesopotamian cuneiform system to a language other than Sumerian.

The frequency and intensity of their use varied depending on period, style, and genre.

[1] In the transliteration of ancient texts Sumerograms are normally represented by majuscule letters.

The scribes and readers of texts using these Sumerograms would not necessarily have been aware of the Sumerian language, with the Sumerograms functioning as ideograms or logogram to be substituted in pronunciation by the intended word in the text's language, such as Akkadian.

In the Amarna letters, Lady of the Lions is the name of a Babylonian Queen mother, spelled as NIN.UR.MAH.MEŠ.
