English-speakers usually say "Bosnian Muslims" when they mean Bosniaks, but this is not completely correct because not all Bosniaks are Muslims. Partly because of this, ever since the country Yugoslavia broke up, people have started to say "Bosniak" instead of "Muslim" as an official way to talk about this group of people ethnic term to avoid confusion. They also say "Bosnians", but this word can mean anyone from Bosnia or Herzegovina, not just members of the Bosniak ethnic group.
