Almost all words are inflected according to their roles in the sentence: verbs, nouns, pronouns, numerals, adjectives, and some particles.

Advocates of a genetic relation between Indo-European and Uralic maintain that the borrowings can be filtered out by application of phonological and morphological analysis and that a core of
