Italian language in Croatia
As of 2009, the Italian language is officially used in twenty cities and municipalities and ten other settlements in Croatia, according to the European Charter for Regional or Minority Languages. It is an officially recognized minority language in Istria County, where it is spoken by 6.83% of the population on the aggregate and closer to 50% of the population in certain subdivisions.
Serbo-Croatian
Enisa Kafadar argues that there is only one Serbo-Croatian language with several varieties. This has made it possible to include all four varieties in a new grammar book. Daniel Bunčić concludes that it is a pluricentric language, with four standard variants spoken in Serbia, Croatia, Montenegro and Bosnia and Herzegovina. The mutual intelligibility between their speakers "exceeds that between the standard variants of English, French, German, or Spanish". Other linguists have argued that the differences between the variants of Serbo-Croatian are less significant than those between the variants of English, German, Dutch, and Hindi–Urdu.
