Comment: Cf. also Lezg. Khl. sew (with metathesis of labialisation < *s:ʷeʔ), Tab. Düb. š̌eʔe, Tsakh. Gelm. soj. Strong *s:ʷ- is suggested by Ud. š- (all other languages present do not show a clear distinction of *sʷ and *s:ʷ). 3d class in all class-distinguishing languages. The oblique base may be safely reconstructed as *s:ʷeʔ-rV-, cf. Lezg. sewre-, Tab. Kand., Düb. š̌eʔra-, Rut. sirɨ-. The oblique base superseded the direct one in Kryz. and Bud.
