Proto-North Caucasian: *c̣ämc̣V
Meaning: piece, crumb
Notes: An expressive reduplicated root. The development in PN is irregular (-nc̣- in Chech. instead of expected -tt-), which should be obviously explained by the root's expressive nature. The root is similar phonetically and semantically to *c̣ŏc̣V 'tip, spout' (q.v.), and the two roots could have merged in some subgroups.
