Comments:ССЕ 237. A contracted form is probably present in Ket śuk-kɔĺ 'back of head' (*suga 'back' + *k[ǝ]ŕga 'head') (Werner's 2, 212 analysis as śuk 'back' + hɔĺ 'face, form' seems less likely). The PY reconstruction is somewhat complicated: Werner (1, 460) reconstructs <*kʌj- / *kʌl->, not specifying what he means by such an alternation. The equation Ket kʌjga = Arin kolḱā speaks unambiguously of PY *k[ǝ]ŕga. The word may indeed be an old compound with an unclear second part *-ga (as Werner writes ibid.); for the first part cf. Ket kʌ́je (ibid.) 'head; head, leader' - but this can be just a dialectal (Southern) variant pronunciation of the same kʌjga.
