Hello.
I have a question. How is It with people, who speaks standard German and Swiss standard German?
For example meets two persons in Switzerland, but German speaker of standard German from Germany, or ustria don't understand standard Swiss German. So, both knows standard German, or not?
Or, which language will use?
Thank You.
Marco

The languages both have very small differences in spelling. For example, ß always becomes ss in swiss German. Also, some words have different articles going with them, like "Das Email" in swiss German and "Die Email" in standard German, but those differences shouldn't keep you from understanding either variety. Where it gets a bit complicated are the dialects, which most people speak in switzerland.

Let me explain It now.
I am writing storry and there is, that people, who speaks mostly standard German, or austrian German are in Zürich and I don't know now, how they'll speaks, because this swiss German is different from standard, or austrian German.

Hmmm, ok. If you want to look at how they speak, they always use this dialect, which I can't say that I'm familiar with terribly well. I only know about the two standard varieties and those little differences I pointed out in my previous post.

It's hard to explain in written form how they speak, I bet you'll find stuff online, for example on YouTube or something.

isn't it, and French people can tell me differently, but... isn't it like english in UK and English in Australia or here in New Zealand. we speak the same english but some of he words we use are different.

Exactly!

Well, but Swiss German in Swiss German is written like Schweissertüütsch, as far as I remember, and this is quite different from Deutsch.
This way of spelling I encountered so many years ago and now I don't even remember where, so it's most likely not totally accurate.

That's probably the onomatopoeic transcription of the dialect. But I don't think this is used in formal situations. You do hear it on the radio, but I think, at least I remember it that way from my experience, the news are read in standard German.

Standard German being used officially is quite likely, because this is the case for Arabic as well. There is that Modern Standard Arabic and all the different Arab countries also have their own dialects due to historical differences and their colonial past with Britain and France. So a Syrian can't understand a Moroccan and even some Moroccans consider their dialect to have deviated from Arabic so much that it is now a separate language, but you would hear Modern Standard Arabic on the radio and TV in every state where Arabic is an official language and worldwide.

When I was in Basel the Corona hints in supermarkets were in "schwizerdütsch".

Well, I remember something with double "ü", but you must have spelled it much more accurately anyway.
