Elamite radically reduced the number of cuneiform glyphs. From the entire history of the script, only 206 glyphs are used; at any one time, the number was fairly constant at about 130. In the earliest tablets the script is almost entirely syllabic, with almost all common Old Akkadian syllabic glyphs with CV and VC values being adopted. Over time the number of syllabic glyphs is reduced while the number of logograms increases. About 40 CVC glyphs are also occasionally used, but they appear to have been used for the consonants and ignored the vocalic value. Several determinatives are also used.
