Protoform: *=uc̣- / *c̣V-n-
Meaning: to plane, hew
Avar: =uc̣-
Chadakolob: =oč̣-
Akhvakh: č̣a-nu-
Comments: Stem 1 is reflected in Av., stem 2 (with a nasal suffix of secondary nature) - in Akhv. The word for "chip, sliver" in some Andian languages may be derived from this root(as it is in other EC languages), but the problem is that it contains PA *c̣: (even with some irregular reflexes): Cham. ṣinṣ, Gig. c̣:ic̣:in, Tind. ḱ:inḱ:i (sic!) - an irregular (expressive) transformation?
