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.
