Comments:АПиПЯЯ 71, Лексика 172. Cf. also Mong. aŋgat 'аркалик (птица)' ( < Turk.); but for *aŋgir borrowing is hardly possible, despite TMN 2, 130, Щербак 1997, 192. Mong. -r here requires an explanation: it is most probably a result of reinterpreting the original *aŋgid as a plural form and rebuilding a new singular *aŋgir (cf. *nökör - *nököd etc.). The word is widely spread in Siberian languages, see Аникин 70.
