I understand why it would appear this way; however, "dere" in meant to address a group of individuals in the 2nd person - equivilent to the american southern "you all" or "y'all".
An example would be a teacher telling her classroom.."YOU GUYS need to calm down". It would not make sense for the teacher to address the students saying "THEY need to calm down."
5/26/19. I was just marked wrong for writing "do you speak norwegian" (as copy/pasted from the answer field) to a type-what you-hear exercise. The only difference between my answer and the correct answer appears to be capital letters D and N - is capital correction a new thing?
I tried to report it, but the option for "my answer should be accepted" wasn't available. And I even spelled norwegian right :P
Because they do not have such a rule that tells you to capitalise nationalities. Czech and Polish, which I learn primarily, do not capitalise them either. I think there are many languages out there that don't consider the capitalisation of nationalities important enough to make it a grammatical rule.
