Italian (italiano) is a Romance language spoken by 65–75 million native speakers and over 125 million total speakers worldwide. It is the official language of Italy, Switzerland (Ticino & Grisons), San Marino, and Vatican City, with co-official status in parts of Slovenia and Croatia (Istria).
Descended from Vulgar Latin, Italian standardized on the Tuscan dialect (particularly Florentine) thanks to the literary works of Dante, Petrarch, and Boccaccio in the 13th–14th centuries.
Italian shaped Western art, music (opera: Verdi, Puccini, Monteverdi), literature, science, and cuisine. It remains a major language of the Catholic Church and international culture.
