Comments:VEWT 426, ЭСТЯ 7. Stachowski (193) relates here also Yak. ono-ɣos, Dolg. ono-gos 'arrow', which may be right if onoɣos < *sagun-gač with secondary vowel shortening (although the root should be kept distinct from *sokɨm / *sokan, derived from *sok- 'to pierce, hit' - medial *-g- cannot be explained). See also notes to *sAgut 'vessel'.
