Comments: PTsKh *ʕomoq̇e. The Bezht. form can be related here if it goes back to PGB *ʔɔ̃q̇u ( < *ʔɔm-q̇u).
The component *-q̇V in the PTs form is not clear etymologically. There also could have existed a PTs variant *ʕɨmVrV ( = PL *ʡimal), reflected (with a productive suffix *-ṭu) in PGB *ʔɨrmV-ṭu (Bezht. irmaṭo, Gunz. ɨrmǝṭu) 'ass'.
