Cuneiform sign: 𒆬
Sign name: KU3
Phonetic values: ku3, kug
UTF-8 Symbol: U+121AC
Category: Space-time diagram
Sub-signs: none
Visual analysis: Time flows from right to left. The two obtuse angles ❯ on the right symbolize that two processes are unfolding. Four strokes in a row can stand for a process of consciousness or a conscious being. The sign thus concerns two processes of consciousness. The outer frame delimits the sphere of influence of the processes of consciousness. The single angle ❮ on the left shows that both processes of consciousness merge into one consciousness.
Derived meaning: The sign describes the merging of two processes of consciousness. This presumably concerns a human consciousness that merges with a consciousness from the divine sphere. If it concerns the consciousness of a god, then the meaning of the sign is "incarnation." If it concerns a so-called oversoul, then the meaning of the sign is "mental purity."
Usage: There are different types of usage:
- As a noun, the sign 𒆬 has the meanings "purity" and "incarnation"; as a verb, it has the meaning "to ritually purify"; and as an adjective, the meanings "pure" and "holy."
- In addition to the meanings supported by the visual analysis, the sign 𒆬 also has the meaning "silver": presumably, the Sumerians assumed that shining metals such as silver are "ensouled" by the divine.
Conventional interpretation: silver, to ritually purify, pure, holy, consecrated
