Finno-Ugric is a traditional linguistic grouping of all languages in the Uralic language family except for the Samoyedic languages. Its once commonly accepted status as a subfamily of Uralic is based on criteria formulated in the 19th century and is criticized by contemporary linguists such as Tapani Salminen and Ante Aikio. The three most spoken Uralic languages, Hungarian, Finnish, and Estonian, are all included in Finno-Ugric.
