Albanians
In Croatia, the Albanian language is one of the officially recognized minority languages of the country and is primarily spoken by the Albanians and Arbanasis. As defined in the 2011 census, the number of Albanians in the country was estimated to be 17,513. They are mostly concentrated in the coastal cities of Croatia and the capital city of Zagreb.
Serbo-Croatian
Enisa Kafadar argues that there is only one Serbo-Croatian language with several varieties. This has made it possible to include all four varieties in a new grammar book. Daniel Bunčić concludes that it is a pluricentric language, with four standard variants spoken in Serbia, Croatia, Montenegro and Bosnia and Herzegovina. The mutual intelligibility between their speakers "exceeds that between the standard variants of English, French, German, or Spanish". Other linguists have argued that the differences between the variants of Serbo-Croatian are less significant than those between the variants of English, German, Dutch, and Hindi–Urdu.
