M. Streck (2000:117) considers ṣūru ‘cliff, rock’ in an OB Gilgameš tablet from Tell Harmal a WS loanword, but a rare but authochnous Akkadian lexeme cannot be ruled out completely (Kogan 2015: 203)
Akkadian
-ša - her (genitive pronominal suffix)
(GAG § 42 g)
In Akkadian there is a vocalic opposition between genitive and accusative forms of 3 fem. sg. pronominal suffixes. See -ši.
Akkadian
šaˀāru - to be victorious, to vanquish
