Finnish (endonym: or ) is a Finnic language of the Uralic language family, 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, alongside Swedish. In Sweden, both Finnish and Meänkieli (which has significant mutual intelligibility with Finnish) are official minority languages. Kven, which like Meänkieli is mutually intelligible with Finnish, is spoken in the Norwegian counties of Troms and Finnmark by a minority of Finnish descent. However, these are recognized as independent languages in their relative countries for sociohistorical reasons.

Finnish is typologically agglutinative 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 differently. Word order variations are often reserved for differences in information structure. Finnish orthography uses a Latin-script alphabet derived from the Swedish alphabet, and is phonemic to a great extent. Vowel length and consonant length are distinguished, and there are a range of diphthongs, although vowel harmony limits which diphthongs are possible.

Classification Finnish belongs to the Finnic branch of the Uralic language family; as such, it is one of the few European languages that is not Indo-European. The Finnic branch also includes Estonian and a few minority languages spoken around the Baltic Sea and in Russia's Republic of Karelia. The closest relative of Finnish is either Ingrian, or depending on the definition, Karelian. Finnic languages form a dialect continuum, where for instance Finnish and Estonian are not separated by any single isogloss that would separate dialects considered "Finnish" from those considered "Estonian", despite the two standard languages being not mutually intelligible.

Finnish demonstrates an affiliation with other Uralic languages (such as Hungarian and Sami languages) in several respects including:

Shared morphology: case suffixes such as genitive , partitive / ( < Proto-Uralic , originally ablative), essive / ( < , originally locative) plural markers and ( < Proto-Uralic and , respectively) possessive suffixes such as 1st person singular ( < Proto-Uralic ), 2nd person singular ( < Proto-Uralic ). various derivational suffixes (e.g. causative < Proto-Uralic ) Shared basic vocabulary displaying regular sound correspondences with the other Uralic languages (e.g. 'fish' ~ North Saami ~ Hungarian ; and 'disappear' ~ North Saami ~ Hungarian 'leave (behind)'.

Several theories exist as to the geographic origin of the most recent common ancestor of Finnish and the other Uralic languages (Proto-Uralic). The most widely held view is that it originated somewhere in the boreal forest belt around the Ural Mountains region and/or the bend of the middle Volga. The strong case for Proto-Uralic is supported by common vocabulary with regularities in sound correspondences, as well as by the fact that the Uralic languages have many similarities in structure and grammar. Despite having overlapping geographical distributions, Finnic languages and Sami languages are not closely related, and the hypothesis of a separate taxonomic "Finno-Samic" node is controversial.

The Defense Language Institute in Monterey, California, United States, classifies Finnish as a level III language (of four levels) in terms of learning difficulty for native English speakers.

Geographic distribution

Finnish is spoken by about five million people, most of whom reside in Finland. There are also notable Finnish-speaking minorities in Sweden, Norway, Russia, Estonia, Brazil, Canada, and the United States. The majority of the population of Finland (90.37% ) speak Finnish as their first language. The remainder speak Swedish (5.42%), one of the Sámi languages (for example Northern, Inari, or Skolt), or another language as their first language. Finnish is spoken as a second language in Estonia by about 167,000 people. The Finnic varieties found in Norway's Finnmark (namely Kven) and in northern Sweden (namely Meänkieli) have the status of official minority languages, and thus can be considered distinct languages from Finnish. However, since these languages are mutually intelligible, one may alternatively view them as dialects of the same language.

No language census exists for Norway, neither for Kven, standard Finnish, or combined. As of 2023, 7,454 first- or second-generation immigrants from Finland were registered as having Norwegian residency, while as of 2021, 235 Finns were registered as foreigners studying at Norwegian higher education. Great Norwegian Encyclopedia estimates Kven speakers at 2,000-8,000. Altogether, this results in a total amount of Finnish-speakers roughly between 7,200 and 15,600.

In the latest census, around 1000 people in Russia claimed to speak Finnish natively; however, a larger amount of 14,000 claimed to be able to speak Finnish in total.

There are also forms of Finnish spoken by diasporas outside Europe, such as American Finnish, spoken by Finnish Americans, and Siberian Finnish, spoken by Siberian Finns.

Official status Today, Finnish is one of two official languages of Finland (the other being Swedish), and has been an official language of the European Union since 1995.

Finnish also enjoys the status of an official minority language in Sweden. Under the Nordic Language Convention, citizens of the Nordic countries speaking Finnish have the opportunity to use their native language when interacting with official bodies in other Nordic countries without being liable to any interpretation or translation costs. However, concerns have been expressed about the future status of Finnish in Sweden, for example, where reports produced for the Swedish government during 2017 show that minority language policies are not being respected, particularly for the 7% of Finns settled in the country.

History

Prehistory The Uralic family of languages, of which Finnish is a member, are hypothesized to derive from a single ancestor language termed Proto-Uralic, spoken sometime between 8,000 and 2,000 BCE (estimates vary) in the vicinity of the Ural Mountains. Over time, Proto-Uralic split into various daughter languages, which themselves continued to change and diverge, yielding yet more descendants. One of these descendants is the reconstructed Proto-Finnic, from which the Finnic languages developed.

Current models assume that three or more Proto-Finnic dialects evolved during the first millennium BCE. These dialects were defined geographically, and were distinguished from one another along a north–south split as well as an east–west split. The northern dialects of Proto-Finnic, from which Finnish developed, lacked the mid vowel . This vowel was found only in the southern dialects, which developed into Estonian, Livonian, and Votian. The northern variants used third person singular pronoun instead of southern (Est. ). While the eastern dialects of Proto-Finnic (which developed in the modern-day eastern Finnish dialects, Veps, Karelian, and Ingrian) formed genitive plural nouns via plural stems (e.g., eastern Finnish < ), the western dialects of Proto-Finnic (today's Estonian, Livonian and western Finnish varieties) used the non-plural stems (e.g., Est. < ). Another defining characteristic of the east–west split was the use of the reflexive suffix , used only in the eastern dialects.

Medieval period

The Birch bark letter no. 292 from the early 13th century is the first known document in any Finnic language; it is written in a variety that is closest to modern Karelian or Veps. The first known written example of Finnish itself is found in a German travel journal dating back to : (Modern Finnish: "" English: "I want to speak Finnish, [but] I am not able to"). According to the travel journal, the words are those of a Finnish bishop whose name is unknown. The erroneous use of (Modern Finnish ) in the accusative case, rather than in the partitive, and the lack of the conjunction are typical of foreign speakers of Finnish even today. At the time, most priests in Finland spoke Swedish.

During the Middle Ages, when Finland was under Swedish rule, Finnish was only spoken. At the time, the language of international commerce was Middle Low German, the language of administration Swedish, and religious ceremonies were held in Latin. This meant that Finnish speakers could use their mother tongue only in everyday life. Finnish was considered inferior to Swedish, and Finnish speakers were second-class members of society because they could not use their language in any official situations. There were even efforts to reduce the use of Finnish through parish clerk schools, the use of Swedish in church, and by having Swedish-speaking servants and maids move to Finnish-speaking areas.

Writing system

The first comprehensive writing system for Finnish was created by Mikael Agricola, a Finnish bishop, in the 16th century. He based his writing system on the western dialects. Agricola's ultimate plan was to translate the Bible, but first he had to develop an orthography for the language, which he based on Swedish, German, and Latin. The Finnish standard language still relies on his innovations with regard to spelling, though Agricola used less systematic spelling than is used today.

Though Agricola's intention was that each phoneme (and allophone under qualitative consonant gradation) should correspond to one letter, he failed to achieve this goal in various respects. For example, , , and were all used for the phoneme . Likewise, he alternated between and to represent the allophonic (like th in English this), between and to represent (like th in thin, but longer in duration), and between and to represent the allophonic . Agricola did not consistently represent vowel length in his orthography.

Others revised Agricola's work later, striving for a more systematic writing system. Along the way, Finnish lost several fricative consonants in a process of sound change. The sounds and disappeared from the language, surviving only in a small rural region in Western Finland. In the standard language, however, the effect of the lost sounds is thus: became . The sound was written ⟨d⟩ or ⟨dh⟩ by Agricola. This sound was lost from most varieties of Finnish, either losing all phonetic realization or being pronounced as , , , or instead (depending on dialect and the position in the word). However, Agricola's spelling ⟨d⟩ prevailed, and the pronunciation in Standard Finnish became through spelling pronunciation. became . These interdental fricatives were written as ⟨tz⟩ (for both grades: geminate and short) in some of the earliest written records. Though these developed into a variety of other sounds depending on dialect (, , , , , or ), the standard language has arrived at spelling pronunciation (which is treated as a consonant cluster and hence not subject to consonant gradation). became: if it appeared originally between high round vowels and (cf. 'kin, family' : [genitive form] from earlier , and : 'ability, skill' [nominative and genitive, respectively] from , contrasting with : 'pig, pork' [nominative and genitive] from . A similar process explains the pronunciation for some English words with "gh", such as "tough"), between a liquid consonant or and a vowel (like in 'I go', a form of the verb 'to go' that was originally ), and otherwise it was lost entirely.
