Finnish language

Finnish is a Finnic language belonging to the Uralic language family.

It is spoken by approximately five million people worldwide. Most of these speakers live in Finland, where it is one of two official languages. The other official language is Swedish. Finnish is also an official language of the European Union. Beyond Finland, significant Finnish-speaking populations exist in Sweden and Norway. These groups include the Meänkieli and Kven speakers.

These varieties are mutually intelligible with Finnish. Small communities also speak Finnish in Russia, Estonia, Brazil, Canada, and the United States.

The structure of Finnish is typologically agglutinative. This means the language relies heavily on suffixal affixation. Suffixes are small parts added to the end of a word to change its meaning. In Finnish, nouns, adjectives, pronouns, numerals, and verbs are all inflected. This inflection depends on the specific role the word plays in a sentence. While the standard word order is subject–verb–object, the system of inflection allows for flexibility. Speakers can reorder words to change the information structure of a sentence.

This allows the speaker to emphasize different parts of the message.

The Finnish writing system uses a Latin-script alphabet. This alphabet was derived from the Swedish alphabet. The orthography is largely phonemic, meaning letters represent specific sounds. However, the language has complex rules regarding sound. Vowel length and consonant length are distinct features that change word meanings. The language also utilizes diphthongs, which are two vowel sounds joined in one syllable. These are governed by vowel harmony. Vowel harmony is a rule that limits which specific vowels can appear together in a word.

Finnish is unique among European languages because it is not Indo-European. Instead, it belongs to the Finnic branch of the Uralic family. This branch includes Estonian and several minority languages near the Baltic Sea. The closest relatives to Finnish are Ingrian or Karelian.

Linguists believe these Finnic languages form a dialect continuum. This means there are no sharp boundaries separating different dialects. While standard Finnish and Estonian are not mutually intelligible, they share deep connections. Finnish also shares morphological traits with other Uralic languages like Hungarian and Sami. These include shared case suffixes, such as the genitive and partitive cases. They also share common basic vocabulary, like words for "fish."

The history of the language traces back to Proto-Uralic. Most scholars believe this ancestor language originated near the Ural Mountains. It was likely spoken between 8,000 and 2,000 BCE. Over time, Proto-Uralic split into various daughter languages. One descendant was Proto-Finnic, which further split into several dialects during the first millennium BCE. A north–south split distinguished northern dialects from southern ones. For example, northern dialects lacked the mid vowel "e."

The earliest known document in a Finnic language is a birch bark letter from the 13th century. It is written in a variety close to modern Karelian or Veps.

For a long time, Finnish lacked official status in Finland. During the period of Swedish rule, which ended in 1809, Swedish was the language of administration. Most priests also spoke Swedish. Finnish was used primarily for everyday life and was often considered inferior. This changed due to the Fennoman movement. In 1863, the Finnish Diet granted the language official status.

Mikael Agricola, a 16th-century bishop, was vital to this development. He created the first comprehensive writing system for Finnish. He based his orthography on Swedish, German, and Latin. His work laid the foundation for the modern standard language.

Learning Finnish presents specific challenges for certain speakers. The Defense Language Institute classifies it as a level III language. This ranking is based on its difficulty for native English speakers. One reason for this is the complex system of consonant gradation. This involves changes in the sounds of consonants within a word. Some historical sounds, like certain interdental fricatives, were lost in the standard language. However, their influence remains in modern spelling.

For example, the spelling "d" is often used even when the original sound has changed. This creates a unique relationship between how the language is written and how it is spoken.
