Here comes the catch.
My English stinks, so I would like the dictionary be Swedish/Norwegian/Danish/German – Icelandic, and it would help, too, if the grammar was meant for someone who speaks a North-Germanic language as their first language.
I'd prefer a book, really, it helps me to concentrate, and I have already found a bunch of quite good (and reliable-looking) online sources, in case you guys can't help me out with this one. Tips, anyone? Recommendations?
EDIT:
I'm bilingual, so that makes Finnish and Swedish my first languages. My Finnish is a bit better than my Swedish, but I don't think there's such a big difference.
