Minority languages of Croatia
The Istro-Romanian language is one of the smallest minority languages spoken in Croatia with fewer than 500 speakers concentrated mainly in the north-eastern part of the Istrian Peninsula. While the language is not officially recognized in the Constitution of Croatia under that name (the Constitution does reference Romanians and Vlachs), it is specifically recognized as such in the Statute of the Istrian Region and in the Statute of the Municipality of Kršan . In 2016, with funding from the Romanian government, the school in the village of Šušnjevica was fully renovated and is expected to start offering education in Istro-Romanian.
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.
