Comments:ОСНЯ 2, 86, АПиПЯЯ 295. See SKE 159, EAS 75 (Mong.-Kor.); one frequently links Turk. *jāŕ 'spring' (see SKE ibid., KW 272, VEWT 193), but the latter should be separated (see *ni̯ā́ŕ[à]); instead it seems plausible to compare Turk. *jarɨ-n 'tomorrow, morning' - see Лексика 80-81. TM *ŋēr(i)- 'light' is a perfect phonetic and semantic match and should be separated from Mong. gere-l 'light' (especially because the rule *ŋ- > Mong. g- is most probably false) - despite KW 134, Poppe 25, ОСНЯ 1, 228-229, АПиПЯЯ 18, Дыбо 11; on the etymology of the latter see under *gari (despite Poppe 1972, 101, Doerfer MT 21, the TM form of course cannot be borrowed from Mong. gerel).
