Comments: Av. paradigm C (ṭulá-l,ṭúla-l). We should note that the position of the Avar word is somewhat dubious: it may belong here only if ṭ < *ƛ̣ (then it would be a metathesized form of the same root which is reflected in all Andian languages). However, there seems to be (in this particular case) no evidence from Southern Avar dialects for Proto-Avar *ƛ̣ - all dialectal forms seem to point to *ṭ. Thus the Avar word is either unrelated, or the dialectal evidence should be explained by borrowing from literary Avar.
As for Andian languages, the simple root *riƛ̣V is reflected only in Botl. (where rehi-n < *reʔi-n < *riƛ̣i-n with a suffixed -n) and Kar. Tok. relʔi-r (with suffixed -r). All other forms go back to a compound *riƛ̣a-jiƛ:i (see *riƛ:i for etymology of the second part). Cf. also Bagv. Tlis. releƛ, Akhv. Tseg. riṭajiƛ:i, Tlan. ruṭeƛ:i, Ratl. riƛ̣ajƛ:i, Cham. Gig. relaƛ etc.
