Finnish (endonym: suomi [ˈsuo̯mi] (About this soundlisten) or suomen kieli [ˈsuo̯meŋ ˈkie̯li]) is spoken by the majority of the population in Finland and by ethnic Finns outside Finland. Finnish (a Uralic language of the Finnic branch), along with Swedish, are the two official languages of Finland. In Sweden, both Finnish and Meänkieli (which has significant mutual intelligibility with Finnish[5]) are official minority languages. The Kven language, which like Meänkieli is mutually intelligible with Finnish, is spoken in Norway's Finnmark by a minority group of Finnish descent.

Finnish is typologically agglutinative[6] and uses almost exclusively suffixal affixation. Nouns, adjectives, pronouns, numerals and verbs are inflected depending on their role in the sentence. Sentences are normally formed with subject–verb–object word order, although the extensive use of inflection allows them to be ordered otherwise, and word order variations are often reserved for differences in information structure.[7] The orthography is a Latin-script alphabet derived from the Swedish alphabet, and for the most part each grapheme corresponds to a single phoneme and vice versa. Vowel length and consonant length are distinguished, and there are a range of diphthongs, although vowel harmony limits which diphthongs are possible.
