Nynorsk is one of the two official written standards of the Norwegian language, the other being Bokmål. Developed in the 19th century by linguist Ivar Aasen, Nynorsk is based on various Norwegian dialects, aiming to create a language that reflects the country's rural heritage. Nynorsk is used by about 10-15% of the Norwegian population, primarily in western Norway. It is taught in schools and used in government, media, and literature, promoting cultural identity and linguistic diversity within Norway.
