The official language of Switzerland is German, French, Italian, and Romansh. Switzerland is a multilingual country, with these four languages recognized officially at the federal level. German is the most widely spoken language and is used predominantly in the central and northern regions. French is mainly spoken in the west, known as the Romandy region. Italian is primarily spoken in the southern region, particularly in Ticino, while Romansh is used by a small percentage of the population in certain areas of the Graubünden canton. This linguistic diversity reflects Switzerland's rich cultural heritage.
