I remember asking somewhere in one of the exercises about the position of small words like nic, which, I saw, would usually be placed at the beginning of a sentence.
Is "Nie wiesz nic o niej" wrong or is it a question of emphasis?
I think it would be extremely helpful to put the case in the hints for pronouns! It would eliminate the need for some guessing
Unfortunately that's the opposite of what Duolingo wants us to do, because it messes with the puzzle exercises.
