Norwegian (norsk) is a North Germanic language spoken primarily in Norway, where it is the official language. Together with Swedish and Danish, Norwegian forms a continuum of more or less mutually intelligible local and regional variants.
As established by law and governmental policy, there are two official forms of written Norwegian – Bokmål (literally "book tongue") and Nynorsk (literally "new Norwegian"). The Norwegian Language Council is responsible for regulating the two forms, and recommends the terms "Norwegian Bokmål" and "Norwegian Nynorsk" in English. Two other written forms without official status also exist, the major one being Riksmål ("national language"), which is somewhat closer to the Danish language but today is to a large extent the same language as Bokmål. It is regulated by the Norwegian Academy, which translates the name as "Standard Norwegian". The other being Høgnorsk ("High Norwegian") that is a more purist form of Nynorsk, which maintains the language in an original form as given by Ivar Aasen and rejects most of the reforms from the 20th century. This form of Nynorsk has very limited use.
