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.
Croatian language
Standard Croatian is based on the most widespread dialect of Serbo-Croatian, Shtokavian, more specifically on Eastern Herzegovinian, which is also the basis of Standard Serbian, Bosnian, and Montenegrin. In the mid-18th century, the first attempts to provide a Croatian literary standard began on the basis of the Neo-Shtokavian dialect that served as a supraregional "lingua franca" pushing back regional Chakavian, Kajkavian, and Shtokavian vernaculars. The decisive role was played by Croatian Vukovians, who cemented the usage of Ijekavian Neo-Shtokavian as the literary standard in the late 19th and the beginning of the 20th century, in addition to designing a phonological orthography. Croatian is written in Gaj's Latin alphabet.
