Northern Sami is a language spoken in the northern parts of Scandinavia. It is a member of the Sami language family, and is closely related to the other Sami languages: Southern Sami, Lule Sami, Inari Sami, and Skolt Sami.
The Sami languages are thought to be descended from a Proto-Sami language, which was spoken in the area around the Volga River in what is now Russia. The Sami languages began to diverge from each other around the 3rd century AD.
Northern Sami is the largest and most widely-spoken of the Sami languages, with around 20,000 speakers. It is written with a Latin-based alphabet, and has official status in Norway, Sweden, and Finland.
The grammar of Northern Sami is similar to that of other Sami languages. It is a highly inflected language, with four grammatical genders and numerous case endings. Sami languages are also known for their complex system of verb conjugations.
Northern Sami has a rich vocabulary, with loanwords from Scandinavian languages, Russian, and other languages. The Sami people have their own unique culture and way of life, which is reflected in the language.
