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.
South Slavic languages
This dialect is spoken primarily in the federal state of Burgenland in Austria and nearby areas in Vienna, Slovakia, and Hungary by descendants of Croats who migrated there during the 16th century. This dialect (or family of dialects) differs from standard Croatian, since it has been heavily influenced by German and Hungarian. It has properties of all three major dialectal groups in Croatia, since the migrants did not all come from the same area. The linguistic standard is based on a Chakavian dialect, and (like all Chakavian dialects) is characterized by very conservative grammatical structures: for example, it preserves case endings lost in the Shtokavian base of standard Croatian. At most 100,000 people speak Burgenland Croatian and almost all are bilingual in German. Its future is uncertain, but there is movement to preserve it. It has official status in six districts of Burgenland, and is used in some schools in Burgenland and neighboring western parts of Hungary.
