Akkadian

parṣu - rite, ritual; divine authority; authoritative decision, command, decree (CAD P 195; AHw. 835)

Borrowed into Sumerian as ĝarza(₂) (Kogan 2008b:96, EDA I 307–308, Attinger 2023:630).

PS
*parṣ̂- - order, decision (divine) (Landsberger 1924–1925:68; Kogan 2008:96; EDA I 308; Kogan–Krebernik 2021a:392)

Reflected only in Arabic and ES. See EDA I:308 for the discussion. May ultimately be derived from PS *prṣ̂ with a semantic shift ‘to break, to cut’ > ‘to decide, to order’, cf. Arb. ḥaqq-, Hebr. ḥōḳ < PWS *ḥḳḳ and Arm. gəzērā < PWS *gzr (EDA I:308). Eventually, the possibility of Akk. > Arb. loan, though being barely conceiveable, is not to be completely neglected (Kogan–Krebernik 2021a:390ff.).
