gün 2, güneš 1, (dial.) gujaš 1

1 sun 2 day 3 sunny place 4 sun-heat

*ń in PT. The Jpn. reflex is somewhat problematic: loss of final resonant here may be explained by a standard development before a velar suffix (*ka < *gi̯òjn(u)-gV, cf. Mong. *gege-ɣe, Man. geŋ-ǵe); but one would rather expect a PJ form like *ku(i). The irregular vowel may be due to contraction, cf. a similar case in PJ *ká 'mosquito' < PA *kúńe.

Comments: VEWT 301, 309 (Räsänen separates *gün and *gun'al', which is hardly justified); EDT 679, 725, 734, ЭСТЯ 3, 100-104, 6, 112-113, Лексика 20-21, 64-65, 77-78, Федотов 1 306-307, Stachowski 161, 164. The forms *güńeĺ and *guńaĺ must be old dialectal variants.
