Neapolitan is a Romance language of the Italo-Dalmatian group spoken across much of southern Italy, except for southern Calabria, southern Apulia, and Sicily, and spoken in a small part of central Italy. It is named after the Kingdom of Naples that once covered most of the area, of which the city of Naples was the capital. On October 14, 2008, a law by the Region of Campania stated that Neapolitan was to be protected.
