Icelandic is actually the national and official language of Iceland. The Nordic Council also uses it as one of its official languages. It has over 300,000 speakers in Iceland and over 13,000 in Denmark and the United States. And because there's a region in Manitoba, Canada, called New Iceland, about 1,500 Canadians also speak the language.
It has similarities to Western Norwegian and Faroese, especially in their written forms. And compared to other languages in Western Europe, it's more conservative and synthetic. It retains synthetic grammar and irregular declensions. And every year, on November 16, the people of Iceland widely celebrate Icelandic Language Day.
