Comments: EDT 788, ЭСТЯ 7. Modern languages reveal some very irregular reflexes like Kaz., KKalp. sobɨq 3, Tur. sümek, sömek 1, 2, 3 (with -m- also in Kum. sümek, Nogh. simek, Uzb. sumak 1, 2 etc.; some languages have variants with č- or š- like Kirgh. čömök 3, šimek 1, 2). These all can be either irregular expressive variants with secondary diffusion or reflect contaminations with some other (not quite clear) roots.
