Greece and Bulgaria are neighbouring countries of Turkey. So they tend to speak it more often. Just like Dutch people in the east speak German. We Bosniaks also preserved our culture, language and heritage. We converted to Islam because we were hunted down, killed and mistreated by Catholic croats, Hungarians and orthodox Serbs from the 1qth century u tull we converted to Islam under the ottomans. We were seen as heretics by constantinople and the Vatican because were were agnostics and member of the BOSNIAN CHURCH. we didnt assymite under the ottomans and never lost our language.

I hope this clears it up a bit for you.

Have a nice day.
