Comments:VEWT 116, 118-119, Егоров 320, Федотов 2, 403. An expressive and late attested root; appears, however, to be reconstructable for PT. The original shape is probably *čap- (preserved in čap-ɨr- 'to appear (of rash)', with further labial assimilation into *čopur. The frequently attested variant čupar > čubar is most probably a result of contamination *čopur and *čubar (reflected in Tat. čuwar, Kirgh. čār that can only reflect *-b-).
