"Utu" is actually an Akkadian transmogrification of proper Sumerian "UD".[3][4] It is common in transforming a Sumerian word into Akkadian to change /D/ to /t/, and the final /-u/ is the Akkadian nominative case-ending."

Habar itt azt allitjak, hogy az UTU nev akkad kepzodmeny, UD-bol, szerintem az UD.UD=babbar=feher, feheren izzo jelentesbol johetett letre.

UD.UD>UD.U(D).UDU>UTU, formaban.
