Highly problematic. Only Akk. if, as Kaufman asserts ([Kaufman 56]), the Arm. forms are Akkadisms (which is difficult either to prove or disprove). Cf. what may be related with metathesis in MSA: Mhr. ṣanḫ ‘cooking fat; fat put
on fire to melt’ [ML 365], Hrs. ṣōnəḫ id. [ibid.], Jib. ṣonḫ ‘fat in an animal; fat put on to melt’ [JL 241].
