Or pasultu. No definitive etymology can be suggested.
Akkadian
pašunu - (a profession) (CAD P 269, AHw. 846)
Or pašunnu. In AHw. 846 derived from the Hurrian root fašš- “to send” (BGH 303). Within this approach pašun(n)u could be parsed as a (substantivized) adjective with the suffix -nni (Wegner 2007:55f.): faž(i)-o/u-nni “the one who is sent”. However, the fact that the word is never spelled with double šš does not favour this hypothesis. Alternatively, a similar derivation from f/paž- “to enter” (BGH 302) could be considered. At any rate, the plene spellings are difficult to explain.
