Akkadian
puṣṣû - to crush (?) (CAD P 539, EDA I 416)
If the reading of the verbal form in question as tupaṣṣa ‘you crush’ (CAD) is accepted, the Akkadian lexeme can be compared with several WS verbal roots (see EDA I). Still another possibility is to consider Akk. puṣṣû to be a variant of paʾāṣu (pâṣu) ‘to crush’.
Akkadian
puṣuddu - (a mongoose?) (CAD P 541, AHw. 883)
Var. paṣuddu. No etymology can be suggested.

Akkadian
pušku - span (CAD P 542, AHw. 883)

The Aramaic origin, first proposed for this word by von Soden 1968:263, seems highly probable.

Akkadian
puššuḳu - to explain (CAD P 545)
Most probably a loanword from Aramaic (AHw. 841 pašāqu D mng. 2, CAD P 545, Cherry 2017:205f.). As argued in Cherry 2017:206, the unusual correspondence Aramaic š ~ Assyrian š (instead of the expected s) may be due to the influence of pašāḳu ‘to be narrow’.
Akkadian
puššušu - to chop(?) (CAD P 545, AHw. 1582)
No definitive etymology can be suggested.
Akkadian
putrintu - (a profession) (CAD P 546)
Apparently borrowed from a non-Semitic language. The Anatolian suffix -inn (Dercksen 2007:39f.) or the Hurrian suffix -(n)ni (Wegner 2007:55) is perhaps to be posited.
