Icelandic is the official language of Iceland. It is an Indo-European language, belonging to the sub-group of North Germanic languages. It is closely related to Norwegian and Faroese, although there are slight traces of Celtic influence in ancient Icelandic literature.
Icelandic is an insular language, and as such, has not been influenced greatly by other languages. As a result, the language has changed very little from when the country was settled in the ninth and tenth centuries. It did not become makedly different from Norwegian until the 14th century, when Norwegian became increasingly influenced by its neighbouring languages, Swedish and Danish. Because of this resistance to change, text from the 12th century are still understandable to Icelandic schoolchildren.
