A Sumerogram is the use of a Sumerian cuneiform character or group of characters as an ideogram or logogram rather than a syllabogram in the graphic representation of a language other than Sumerian, such as Akkadian, Eblaite, or Hittite. 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. In the same way, a written Akkadian word that is used ideographically to represent a language other than Akkadian (such as Hittite) is known as an Akkadogram.
In the transliteration of ancient texts Sumerograms are normally represented by majuscule letters. Most signs have a number of possible Sumerian sound values. 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.
