John Emerson has alerted me to the existence of Katerina Potapova, who at My Polyglot Dictionary says “During my study of the Mongolian language I’ve noticed that a lot of words in Mongolian and in my mother tongue – Yakut (a Turkic language in Eastern Siberia) – are of the same origin. And now I’ve decided to make a list of them.” Now, that’s my kind of project! There aren’t many words yet, but you can see them in Yakut (саха тыла), Classical Mongolian in its beautiful original script (UM) and in transliteration, and Khalkha Mongolian, with Russian, German, and English translations. The page has a bibliography and a set of links, and she also has an Online library with materials on Yakut (Sakha) language (Сахалыы-нууччалыы онлайн-библиотека) with links to materials in Russian and Yakut and audio for Pronunciation guide, Yakut proverbs, and Music sample. Good work, Katerina!
