One of the first things one has to get used to in Switzerland is constantly sorting through multiple languages in order to do almost anything.
I already had a fair amount of Italian when Ramesha and I first got together, but it was amazing how much high school French came back to me — and how much German I learned — while grocery shopping or figuring out the bus schedule!
There are four national languages in Switzerland (German, French, Italian, and Romansh), with most every product description appearing in the three “official” languages of German, French, and Italian. A few products will also have information in English, but not that many.
Less than 0.5% of the population of Switzerland speaks Romansh, which I recently learned is a legacy of the Roman conquest of Rhaetia (now the Swiss canton of Graubünden) in 15 B.C. Fascinating stuff!
