today, lack of sources and comparative materials hinder further research of Elamite. Inventory 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. Glyphs in parentheses in the table are not common. The script distinguished the four vowels of Akkadian and 15 consonants, /p/, /b/, /k/, /g/, /t/, /d/, /š/, /s/, /z/, /y/, /l/, /m/, /n/, /r/, and /h/. The Akkadian voiced pairs /p, b/, /k, g/, and /t, d/ may not have been distinct in Elamite. The series transcribed z may have been an affricate such as /č/ or /c/ (ts). /hV/ was not always distinguished from simple vowels, suggesting that /h/ may have been dropping out of the language. The VC glyphs are often used for a syllable coda without any regard to the value of V, suggesting that they were in fact alphabetic C signs. Much of the conflation of Ce and Ci, and also eC and iC, is inherited from Akkadian (pe-pi-bi, ke-ki, ge-gi, se-si, ze-zi, le-li, re-ri, and ḫe-ḫi—that is, only ne-ni are distinguished in Akkadian but not Elamite; of the VC syllables, only eš-iš-uš). In addition, is aḫ, eḫ, iḫ, uḫ in Akkadian, and so effectively is a coda consonant even there. Syntax Elamite cuneiform is similar to that of Akkadian cuneiform except for a few unusual features. For example, the primary function of CVC glyphs was to indicate the two consonants rather than the syllable. Thus certain words used the glyphs for "tir" and "tar" interchangeably and the vowel was ignored. Occasionally, the vowel is acknowledged such that "tir" will be used in the context "ti-rV". Thus "ti-ra" might be written with the glyphs for "tir" and "a" or "ti" and "ra". Elamite cuneiform allows for a lot of freedom when constructing syllables. For example, CVC syllables are sometimes represented by using a CV and VC glyph. The vowel in the second glyph
