Slavs
Standardised Slavic languages that have official status in at least one country are: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Macedonian, Montenegrin, Polish, Russian, Serbian, Slovak, Slovene, and Ukrainian.
Slavic microlanguages
Native speakers of contemporary Slavic microlanguages either live among unrelated linguistic communities, thereby constituting an ethnic "island", or live on the geographical periphery of their historical ethnic group. Correspondingly, these microlanguages can be divided into insular and peripheral categories (the latter of which can also be called "regional languages"). The principal insular forms are: Rusyn, Burgenland Croatian, Molise Croatian, Resian dialect (which may also be characterized as "peninsular") and Banat Bulgarian. The main peripheral forms include Prekmurje Slovene, East Slovak, Lachian, Carpatho-Russian, West Polesian and others.
