Finnish is a Uralic language of the Finnic branch, spoken by the majority of the population in Finland and by ethnic Finns outside of Finland. Finnish is one of the two official languages of Finland. In Sweden, both Finnish and Meänkieli are official minority languages. The Kven language, which like Meänkieli is mutually intelligible with Finnish, is spoken in the Norwegian counties Troms and Finnmark by a minority group of Finnish descent.
