Proto-Altaic: *maŋga (~-o)
Meaning: big, strong
Russian meaning: большой, сильный
Comments: АПиПЯЯ 113, 280. A Tung.-Jpn. isogloss (within Jpn. preserved only in the Ryukyu dialects, where it is the basic word for 'big'). Cf. perhaps Khak., Oyr. maŋ 'success, luck' (if not < OUygh. (Suv.) maŋal < Sanskr. maŋgala). In TM a possible derivative is *maŋ(g)ī 'giant; evil spirit' (ТМС 1, 530) - which brings us to Mong. maŋgus id. (which, despite Doerfer MT 39, can hardly be the source of Tungus words).
