Комментарии:SKE 199 (Turk.-Tung.-Kor.), Цинциус 1984, 37-38, АПиПЯЯ 284, Дыбо 11, Лексика 104. A rather complicated case, because of contractions and compounds. For the second part of the PT compound cf. perhaps Mong. gesi-ɣü(n) 'branch'. The old compound *p`i̯ūju-*gVša, beside Turk. *ɨgač, may be reflected in OJ pàjàsi 'forest', ТМ *pā(j)k[š]a 'wood' (ТМС 2, 311)).
