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.
Croats of Bosnia and Herzegovina
Croats of Bosnia and Herzegovina speak Croatian, a standardized variety of Serbo-Croatian language, spoken by the people of Bosnia and Herzegovina. Even though most of them speak in the Ijekavian, also the norm among Bosniaks and Bosnian Serbs, Ikavian is also used and was widespread in larger parts of Bosnia.
