Thank you, I stand corrected. I believe they are still both Scandinavian. Proto-Germanic, which all of these languages descended from, was spoken primarily in Denmark and Sweden:
Yeah, but you're still sensationally wrong. PGe may have been spoken in Scandinavia, but that's not even close to what people mean when they say “Scandinavian languages”. That means “North Germanic”, or, languages which are descended from Old Norse. As opposed to every other Germanic language, like German, Frisian, Dutch, Old Saxon, Old English, Gothic, etc.
