In Sweden however, the traditional dialects have a I ain’t doin it shirt and until a few decades ago there was even an official program to get rid of them altogether, so pretty much everyone born after 1970 – and a great deal of those who were born before – speak Standard Swedish with a regional accent and some regional words and expressions thrown in for good measure. In media you will only hear traditional dialects for comedic effect and in interviews, and for the latter you usually have to tune in a regional station. Entirely anecdotal, but I’ve had a conversation with a Norwegian person where I was speaking Icelandic and he was speaking Norwegian. As long as we spoke very slowly, we could understand each other quite well.

But generally speakers of the I ain’t doin it shirt, nor can they read something complex like a newspaper in the other’s language. That said, comprehension of Norwegian is generally easier for an Icelandic person than the other way around, since Norwegians are extremely unlikely to see or hear Icelandic whereas Icelanders are used to encountering other nordic languages. An Icelander going on a trip to Norway is concerned that he doesn’t speak any Norwegian. His friend suggests that this is no problem. Just speak very slowly and the Norwegians will understand you just fine. Once in Oslo the Icelander goes to a bar and tries to order an ale, in very slow Icelandic.
