About two-thirds of Swiss people speak Swiss German (a special version of German that even Germans find tricky). Around one in five people speak French - mostly in the west, near the border with France. About one in fifteen speak Italian, mostly in the sunny south near the Italian border. And a tiny number, about 1 in 200, speak Romansh, an ancient language found only in the mountain valleys of one region called Graubünden.
All four languages appear on Swiss money and on official documents. The country's official name has four versions: 'Schweiz' in German, 'Suisse' in French, 'Svizzera' in Italian and 'Svizra' in Romansh. To avoid arguments about which one to use, the country also has a fifth, Latin name on its coins and stamps: 'Helvetia'.
Switzerland's car number plates have 'CH' on them, which stands for 'Confoederatio Helvetica' (Helvetic Confederation in Latin). That way, no one has to pick a favourite language. The football team's shirts also say 'Helvetia' for the same reason.
Most Swiss children study a second national language from primary school onwards. A child in Zurich (German-speaking) might be learning French at age 8. A child in Geneva (French-speaking) might be learning German. By the time they leave school, many Swiss young people can chat with classmates from any part of their country.
