Does this course accept any plural forms of "you", like "you all"?
Many other courses have accepted alternatives to plural "you" so one can get a better understanding of the difference between singular and plural "you". I'm wondering if the Norwegian course allows this? If so, which ones are allowed?
"You all" is an acceptable solution when "dere" must be translated, yes.
Ah I think I just tried it on a sentence and got a mistake, so it got me curious. I will report this next time.
