Translation:I am reading the books and you are reading the letters.
Oh this helped greatly anyways, it's nice to see each form typed out, thank you! I just noticed I wrote my question wrong. My sentence I meat to type this all for "letter/brev". So i read it as "the letter only". Not the letter"S". with the S. since there is no er or ar at the end just an (en) I see it as only "the letter". How am I to know? I hope that makes sense, thank you <3
