Most of the dictionaries of Idel-Ural languages, known to the general public, are dictionaries of Russian-Tatar-Russian, Russian-Bashkir-Russian, Russian-Udmurt-Russian, etc. type in the same style – the language of the empire always acts as an intermediary.
Do you know any dictionaries or tutorials that do not contain any intermediate language so that the peoples of Idel-Ural can learn the languages of their neighbors directly? For example, Erzya-Tatar, Chuvash-Mari, Bashkort-Udmurt and so on.
Share links to such dictionaries, books written simultaneously in two languages, and tutorials (including video/audio lessons) in the comments.
