Proto-Altaic: *p`ī́k`è ( ~ -k-)
Meaning: to file, polish, rub
Russian meaning: пилить, полировать, тереть
Comments: Дыбо 15, Мудрак Дисс. 198, Лексика 399. Mong. egeɣü is probably borrowed from Turkic. Closed *ẹ̄ in Turk. is not quite clear: it is either the result of narrowing in a polysyllabic stem, or a reflex of the lost *p`- (cf. the diphthongization in Chuv. jǝgev).
