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,
Zu (cuneiform) Zu (cuneiform) Cuneiform zu, (also sú, ṣú, and sumerogram ZU (capital letter majuscule)), is an uncommon-use sign in the 1350s BC Amarna letters, the "Epic of Gilgamesh", and other cuneiform texts. Alphabetically, it could conceivably be used for letters "z", "s", "ṣ", or "u"; however in the Amarna letters it is used mostly for "personal names" or "geographical names". In the "Epic of Gilgamesh", sumerogram "ZU", is used to spell the name of god Ninazu, (a name of god Tammuz, two times, Chapter XII, 28, 47). In the "Epic", "ZU" is also used as a logogram, "ZU.AB", for Akkadian language
