You are correct about Rumantsch alessione, there was a fair bit of haggle to decide a common version as well...

My only way of communicating with Swiss-Germans who can't speak French is English. I suspect they even prefer that to talk in German and it's a neutral language, normally both interlocutors will be on equal footing. You expat chaps probably don't really realise how fraught it can be at times when dealing between Swiss French and Swiss German
