Sumerogram

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 or Hittite. Sumerograms are normally transliterated in majuscule letters, with dots separating the signs. 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.
