Bosnia (region)
Bosnia (/Босна; ) is the northern region of Bosnia and Herzegovina, encompassing roughly 81% of the country; the other eponymous region, the southern part, is Herzegovina. "Bosnia" is an informal term for the whole country.
Bosniaks
The Bosniaks (, ; singular masculine: "Bošnjak", feminine: "Bošnjakinja") are a South Slavic nation and ethnic group inhabiting mainly the area of Bosnia and Herzegovina. A native minority of Bosniaks live in other countries in the Balkans; especially in the Sandžak region of Serbia and Montenegro (where Bosniaks form a regional majority), and in Croatia and Kosovo. Bosniaks are typically characterized by their historic tie to the Bosnian historical region, traditional majority adherence to Islam since the 15th and 16th centuries, common culture and Bosnian language. As of 2017 Bosniaks are also recognised as a national minority in Albania.
English speakers frequently refer to Bosniaks as Bosnian Muslims or simply as Bosnians, though the latter term can also denote all inhabitants of Bosnia and Herzegovina (regardless of ethnic identity) or apply to citizenship in the country.
