An excerpt from the article 45 facts about Switzerland

The constitutions of the cantons determine which language or languages are official in the canton - such languages are taught in primary schools, junior high schools, and high schools. At universities, studies are conducted in French or German (in Italian only in the canton of Ticino). A university graduate should be able to speak at least three languages. English is becoming more and more popular in the industrial and advertising environment. In the German-speaking cantons, the everyday language of the Swiss is the Alemannic dialect. German is spoken by the largest number of inhabitants in Switzerland, i.e. 72.8%, French by 13% and Italian by 6.5%.
