"Zdravo" and "zbogov" are Serbian for "hello" and "goodbye" respectively, you see. Once you master that z sound at the beginning before the other consonants they fairly roll off the tongue.
Serbian and Croatian culture, as at-odds-to-put-it-mildly as they have been, both fascinate me. I think it's because the peoples have lived in a fairly small patch of land back in Europe, but have an expansive history. Interestingly my half-sisters are part Croatian, which is cool for them.
There's a guy with a YouTube account who seems to have a pretty good grasp of Serbian pronunciation. Unfortunately he also thinks he's funny, which is why I'm not putting the videos up here.
