Comment: Cf. also Ag. Bursh. jirX̀a-s, Tp. jirħa-s, Rut. dur. =ɨ-rɨχIa-r. In Rut. and Tsakh. the vowel -ɨ- can either reflect PL *i before a pharyngealized consonant or the Ablaut grade *-ɨ- (in Ag. -a- is a result of assimilation, cf. the more archaic forms in Ag. Bursh. and Tp.).
The root has also a nominal derivate meaning 'wound' (a usual semantic development in NC languages): PL *jirχIo-na (Ag. jarX̀un, Rut. jiχIɨn, Tsakh. oχIna).
