Notes: Reconstructed for the PEC level. The verb is well preserved in Nakh, Av., Tsezian and Darg; however, the vocalism is impossible to reconstruct (probably due to distorted Ablaut).
The Lezgian languages have preserved only the old derivate *ruʁV-nV (with metathesis *nuʁVrV) "wound" ( > PL "pus"), reflected also in Av. ruʁun "wound" (Chad. roʁón; Av. > And. ruʁun, Akhv. ruʁu) and PTs *muχru "birth-mark" (PGB *muʁru > Gunz. muʁru, Bezht. Tlad. muhro). Another old derivate from the same root is *rVrʁV "fight, war" reflected in Av. raʁ (gen. raʁú-l) and PD *derʁ (Ak. derʁ, Chir. derʁ, Ur. dirʁ, Kub. dīʁ etc.). A variant *d-VrʁVn is probably reflected in Akhv. dĩʁi 'wound'.
Abdokov (1983, 188) compares WC forms: Abkh. a-ʁá, Abaz. aʁa 'enemy' (PAT *aɣa), as well as Kab. (archaic) āʁ 'angry' which we were unable to locate in existing sources. The comparison is tempting, but for WC one must reconstruct *aGV, with *G not corresponding normally to EC *ʁ - unless the AT forms are actually borrowed from Adygh (in which case a reconstruction *aʁV is also possible). Additional information is required to clear up this situation.
