Switzerland has four unevenly distributed languages and a wealth of dialects. 

German (63.5 %)
German is by far the most widely spoken language in Switzerland: 19 of the country’s 26 cantons are predominantly (Swiss) German-speaking.

French (22.5 %)
French is spoken in the western part of the country, the “Suisse Romande.” Four cantons are French-speaking: Geneva, Jura, Neuchâtel and Vaud. Three cantons are bilingual: in Bern, Fribourg and Valais both French and German are spoken. 

Italian (8.1 %)
Italian is spoken in Ticino and four southern valleys of Canton Graubünden. 

Rhaeto-Rumantsch (0.5 %)
Rumantsch is spoken in the only trilingual canton, Graubünden. The other two languages spoken there are German and Italian. Rumantsch, like Italian and French, is a language with Latin roots. It is spoken by just 0.5% of the total Swiss population. 

Other languages (6.6 %)
The many foreigners resident in Switzerland have brought with them their own languages, which taken as a whole now outnumber both Rumantsch and Italian. The 2000 census showed that speakers of Serbian/Croatian were the largest foreign language group, with 1.4% of the population. English was the main language for 1%.
