Comments:Дыбо 10, Лексика 116. In Jpn. it is difficult (but probably necessary) to distinguish the reflex of this root from *č`i̯ṑk`e 'forage grass' ( > Jpn. *tukusi 'horse-tail') q. v. The Mongolian form also raises problems: it probably reflects a suffixed *č`ik`rV with a development -kr- > -ɣVr- (cf. similarly buɣurčag < *bŭkrV, uɣurga < *uk`rukV / *uk`urkV); otherwise -ɣ- is very hard to explain.
