• In Old Babylonian this sign was also used to represent a glottal stop. When that happens, some Assyriologists assign to this sign the value: ʾa₄. From Middle Babylonian on, the glottal stop was indicated by the sign𒀪, originated as a graphic differentiation of𒄴.

Orthographic borrowing fromSumerian𒄩(ku₆/⁠kud⁠/,“fish”).

𒄩• (KU₆)

1. Sumerogram ofnūnum(“fish”)

An Akkadogram, possibly for𒈦𒄷𒌋𒉿𒅀𒀸(parḫūwayaš).s

𒄩• (KU₆)

1. an animal whose meat was dried and eaten, possibly afish

A term found in the alleged Euphraticsubstrate theory, which connects it toProto-Indo-European*dʰǵʰu-(“fish”). This word in particular is not of atypical syllable structure for being native Sumerian, which is the main sign indicating a potential borrowing into the language. Concurring with the opinion of Pennsylvania State University's Dr. Rubio, the borrowing from multiple languages rather than a specific substratum is now the predominant viewpoint in the field.

𒄩• (ku₆, kud /kud/)

1. fish
