Norwegian language
During the 19th century a slightly different form of Norwegian was made up by several people.  This eventually became known as “Nynorsk.”  It was based on old forms of Norwegian and dialects.  During the 20th century some attempts were made to join Bokmål and Nynorsk into one language, but they did not succeed. Today about one person in nine or ten in Norway writes Nynorsk.  Children in school have to learn both forms.
