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.
Languages of the European Union
Due to the close similarity between Croatian, Serbian, Bosnian, and Montenegrinwhich are mutually intelligibleit was proposed that only one hybrid language be accepted as an official EU language as opposed to four separate ones (as in the International Criminal Tribunal for the former Yugoslavia) in order to reduce translation costs. In negotiations with Croatia, however, it was accepted that Croatian would become a separate official EU language.
