Italian ("italiano" or ) is a Romance language of the Indo-European language family. Italian is, by most measures and together with Sardinian, the closest language to Latin, from which it descends via Vulgar Latin. Italian is an official language in Italy, Switzerland (Ticino and the Grisons), San Marino, and Vatican City. It has an official minority status in western Istria (Croatia and Slovenia). It formerly had official status in Albania, Malta, Monaco, Montenegro (Kotor), Greece (Ionian Islands and Dodecanese) and is generally understood in Corsica by Corsican speakers (in facts, many linguists classify it as an Italian dialect). It also used to be an official language in the former Italian East Africa and Italian North Africa, where it still plays a significant role in various sectors. Italian is also spoken by large expatriate communities in the Americas and Australia. Italian is included under the languages covered by the European Charter for Regional or Minority languages in Bosnia and Herzegovina and in Romania, although Italian is neither a co-official nor a protected language in these countries. Many speakers of Italian are native bilinguals of both Italian (either in its standard form or regional varieties) and other regional languages.
