Tu (cuneiform) Tu (cuneiform) The cuneiform sign tu, and for TU-(the sumerogram, capital letter (majuscule), in the Hittite language and other cuneiform texts, is a common-use syllabic sign for ""tu"", and also with a syllabic use for ""t"", or ""u"". It is not a multi-use sign, with other alphabetic sub-varieties. The Sumerian language version is similar to the usage in the Amarna letters, with the 3-horizontal strokes connecting the 4-angled wedges on the left, and connected to the vertical horizontal single-stroke, at right. Varieties exist: for example Amarna letter EA 271 shows 4-hortizontal long-strokes, with 2 short-strokes, between the two long ones,
Elamite cuneiform to that of the Rosetta Stone's, were written in three different writing systems. The first was Old Persian, which was deciphered in 1802 by Georg Friedrich Grotefend. The second, Babylonian cuneiform, was deciphered shortly after the Old Persian text. Because Elamite is unlike its neighboring Semitic languages, the script's decipherment was delayed until the 1840s. Even today, lack of sources and comparative materials hinder further research of Elamite. 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.
