It's strange that on a small island off the coast of Norway, a language is spoken that we used to call our own, but is now mostly incomprehensible to us. That language is Icelandic.
While mainland Scandinavia went through a language shift beginning in the 14th century, Iceland kept Old Norse alive. Meanwhile, Norway adopted fiddle music from Scotland and peasant fashions from Northern Europe, creating further cultural difference.
On top of that, they learn Danish, not Norwegian, in school.
