Croatian language
Standard Croatian is the official language of the Republic of Croatia and, along with Standard Bosnian and Standard Serbian, one of three official languages of Bosnia and Herzegovina. It is also official in the regions of Burgenland (Austria), Molise (Italy) and Vojvodina (Serbia). Additionally, it has co-official status alongside Romanian in the communes of Carașova and Lupac, Romania. In these localities, Croats or Krashovani make up the majority of the population, and education, signage and access to public administration and the justice system are provided in Croatian, alongside Romanian.
Bartol Kašić
In almost 200 pages and two parts ("books"), he provided the basic information on the Croatian language and explained the Croatian morphology in great detail. The language is basically Shtokavian with many Chakavian elements, mixing older and newer forms. For unknown reasons, the grammar was not accompanied by a dictionary, as was the practice with Jesuit dictionaries and grammars of Croatian.
