Overview
The cuneiform sign TU (also transliterated as tu) is a wedge‑shaped character used in the writing systems of ancient Mesopotamia, primarily in Sumerian and Akkadian texts. It functions both as a phonetic sign representing the syllable /tu/ and, in certain contexts, as a logogram or determinative. The sign is one of the most frequently occurring signs in the corpus of cuneiform tablets.
Form and Variants
- Standard form: The sign consists of a vertical wedge with three to four horizontal wedges extending to the right, resembling a stylized “T” shape.
- Historical variants: Over the course of the third to first millennia BC, the sign evolved in stroke order and angle, leading to minor regional variations (e.g., early Uruk, Early Dynastic, Old Babylonian).
- Unicode: The sign is encoded in the Unicode Standard as U+12152 (𒅒).
Phonetic Value
- In Sumerian, TU represents the syllable /tu/.
- In Akkadian, it conveys the same phonetic value and may be used to write the Akkadian word tû (“to put, place”) or as part of verb stems.
Logographic Uses
- Sumerian: As a logogram, TU can denote the Sumerian verb du (“to place, set”), the noun tú (“place, location”), or related concepts such as “foundation.”
- Akkadian: The sign can function as a logogram for the Akkadian verb šapāru (“to place”) when used in the Sumerian logographic tradition.
Determinative Function
In some lexical lists and administrative texts, TU appears as a determinative preceding proper names of places or institutions, indicating that the following element relates to a location or building.
Frequency and Distribution
Statistical analyses of the Old Babylonian and Neo‑Assyrian corpora show TU among the top 50 most common signs, reflecting its utility in both everyday administrative record‑keeping and literary compositions.

Conclusion
The cuneiform sign TU is a well‑documented element of the Mesopotamian writing system, serving both phonetic and logographic roles across multiple languages and periods. Its consistent presence in the archaeological record makes it a key reference point for the decipherment and interpretation of ancient Near Eastern texts.
