Hi Vane89 and welcome to EF
I hope you’ll have a wonderful time in Lausanne. It is an international city and pretty awesome for students.
Welcome also to billyjim13
Just wanted to throw in my two cents about what you said on “Schwyzer Dootch” (it’s Schweizerdeutsch btw)
Seems kind of inappropriate to say Swiss German didn't 'progress to Hochdeutsch, as if high German was superior to any dialect.
In fact all Swiss German dialects are part of theAlamannic group, the same group that the German spoken in Southern Germany belongs to. This is because the people in the German part of Switzerland are descendants from the Alamannen, who settled in Southwestern Germany, Alsace and Switzerland in the early Middle Ages. The Swiss and Southern German cities had some turbulent relations around the end of the Middle ages and as you might know, Switzerland became independent after an uprising of some German areas against the Habsburg dynasty (Germany).
So it seems to me the reason they didn’t adopt high German were based on creating and maintaining an individual identity.
You didn’t mention if you are now back in Switzerland but either way I hope you have a great rest of the week!
