To add to that, I learnt to basic-speak the now extinct language of Chagatai, because I know Turkish. Turkish is also mutually intelligible with Uzbek and Kazakh - it's basically like English and Dutch. Edit:- Learning Chagatai practically let's you speak Kazakh and Uzbek partway. Tried it in both countries, might work in other places like Kyrgyzstan and Turkmenistan too. :)
