PS

*ˁu/irray(-at)- - intestines; excrement (SED I No. 22, DRS 636)

Scarcely but reliably attested. Phonetic reconstruction highly tentative.

Akkadian
erru - Darm (AHw. 244)
Pl. ‘Eingeweide’ (ibid.).
Akkadian
irrū (wirrū) - intestines, gut (CAD I 181)
The form in w- makes the relationship with PS *ˁu/irray(-at)- ‘intestines’ somewhat problematic (cf. DRS 636).
Arabic
ˁurr-, ˁurrat- - dung of solid-hoofed animals and birds; human excrement (BK 2 205, Lane 1990)
Soqotri
ˁeríyeʰ - disease of intestines (said of livestock) (LS 327)
