Inflection verb, noun, adjective, and adverb, according to its function within a sentence and its relation to surrounding words. The Uralic languages are agglutinative, following from the agglutination in Proto-Uralic. The largest languages are Hungarian, Finnish, and Estonian—all European Union official languages.

Uralic languages three families where gradation "is" found) is noted by Helimski (1995): an original allophonic gradation system between voiceless and voiced stops would have been easily disrupted by a spreading of voicing to previously unvoiced stops as well. A computational phylogenetic study by Honkola, et al. (2013) classifies the Uralic languages as follows. Estimated divergence dates from Honkola, et al. (2013) are also given. Structural characteristics generally said to be typical of Uralic languages include: Basic vocabulary of about 200 words, including body parts (e.g. eye, heart, head, foot, mouth), family members (e.g. father, mother-in-law), animals (e.g. viper, partridge, fish), nature
