Italian language
Italian ("italiano" or ) is a Romance language. Italian, together with Sardinian, is by most measures the closest language to Vulgar Latin of the Romance languages. Italian is an official language in Italy, Switzerland, San Marino, Vatican City and western Istria (in Slovenia and Croatia). It formerly had official status and is still widely spoken in Albania, Malta, Monaco, and in some parts of France (especially Corsica, Nice, Savoie), Greece (Ionian Islands and Dodecanese) and Montenegro (Kotor), as well as in former Italian East Africa and Italian North Africa regions where it plays a significant role in various sectors. Italian is also spoken by large expatriate communities in the Americas and Australia. It also has official minority status in Bosnia and Herzegovina, Croatia, Slovenia and Romania. Many speakers are native bilinguals of both standardized Italian and other regional languages.
