Ottoman Turkish, called simply Osmanlica in Turkish, gradually absorbed a great many Arabic and Persian words and even grammatical forms and was written in Arabic script. Ottoman Turkish today cannot be understood by the modern Turkish people of Turkey. It was a whole new language. The whole reason we have new modern Turkish, is because Ataturk wanted to purge out all the arabic and persian words and somehow go back to the Pre ottoman times Turkish, since the father of Modern Turkish people didn't accept Ottoman as a Turkish language, I think you will find you are mistaken.
I fail to see how Bosnians, Kurds, Armenians, Greeks, etc etc have a Historic and Linguistic connection to the T’u-chüeh.
