I'm an Azeri, who speaks Azeri and Turkish fluently. I'm currently learning Korean and Japanese by myself. Even though I have yet to master both of them, I have studied how they relate to other Altaic languages and have made some connections on my own that were already made by other linguists around the world. I was not even aware of Altaic language family when I started learning Korean, and as I saw how close it was to Turkish grammatically (because the only other language I spoke fluently, that was drastically different, was English), I learned more about its history, which is how I found out about Altaic linguistics. Altaic linguistics is accepted by many linguists, contrary to what is claimed here at Wikipedia. Few people completely reject it, mainly for political reasons.
