It has four official languages
Spend even a short time in Switzerland and you'll quickly notice that its people are incredibly multilingual. And, while German is the most widely spoken language in Switzerland (just over 60% speak it), don't be surprised if your high school German fails you. The languages spoken by each canton symbolize both Switzerland's geographical and cultural limits, as well as the impact on neighboring countries. Italian is spoken to the south and across the Alps, French to the west. Romansh is primarily spoken in the southwest, in the Canton of Graubünden, where Italian and German are also official languages. The cantons of Valais, Fribourg, and Bern are also legally multilingual, speaking both French and German.
If you're planning a vacation across Switzerland's cantons, don't worry; English is commonly spoken, so you don't need to become a polyglot. Picking up two or three phrasebooks, on the other hand, can undoubtedly aid you along the path.
