Switzerland has four national and official languages: German, French, Italian, and Romansh.

• German is the most widely spoken language, used by about 62-63% of the population, mainly in the northern, eastern, and central parts of the country. The spoken form is mostly Swiss German dialects, while written communication uses Standard German

• French is spoken by approximately 22-23% of the population, primarily in western Switzerland (Romandy), including cantons like Geneva, Vaud, Neuchâtel, and Jura. Swiss French is very similar to the French spoken in France

• Italian is spoken by around 8% of the population, mainly in the southern region known as Svizzera italiana

• Romansh is the least common, spoken by about 0.5% of the population, mostly in the canton of Graubünden. It has official status but is used primarily in dealings with Romansh speakers

Additionally, English, while not an official language, is widely used as a lingua franca and in business contexts across Switzerland

. Thus, Switzerland is a multilingual country with four official languages distributed regionally, reflecting its cultural diversity.
