Qut
The cuneiform qut sign, (also qud, aspirated 't', unaspirated 'd') sign is found in both the 14th century BC Amarna letters and the Epic of Gilgamesh. It is a multi-use sign with 9 syllabic/alphabetic uses in the Epic of Gilgamesh; in the Amarna letters it is extremely common in the prostration formula, typical first paragraph of a letter, saying typically: "7 and 7 times, I bow down" (to the Pharaoh, when addressed to the Pharaoh); a small group of Amarna letters are addressed to a different distinct personage in Egypt, under the Pharaoh.
In the Epic of Gilgamesh, the sign is used for many syllabic meanings, as well as two sumerograms, as follows:
The usage numbers for the sign are as follows in the Epic:has-(2), haṣ-(7), kut-(6), qud-(8), qut-(27), šel-(1), šil-(4), tar-(16), ṭar-(9), SILA-(3), for Akkadian language "sūqu", 'street',TAR-(17), exclusively for Ištar's name.
