Latvian (, ), also known as Lettish, is an East Baltic language belonging to the Indo-European language family. It is spoken in the Baltic region, and is the language of the Latvians. It is the official language of Latvia as well as one of the official languages of the European Union. There are about 1.5 million native Latvian speakers in Latvia and 100,000 abroad. Of those, around 1.16 million or 62% of Latvia's population used it as their primary language at home, though excluding the Latgale and Riga regions it is spoken as a native language in villages and towns by over 90% of the population.

As a Baltic language, Latvian is most closely related to neighbouring Lithuanian (as well as Old Prussian, an extinct Baltic language); however, Latvian has developed in different directions. In addition, there is some disagreement whether Standard Latgalian and Kursenieki, which are mutually intelligible with Latvian, should be considered varieties or separate languages.

Latvian first appeared in print in the mid-16th century with the reproduction of the Lord's Prayer in Latvian in Sebastian Münster's (1544), in the Latin script.

Classification Latvian belongs to the Indo-European language family. It is classified as a part of the Baltic branch of the family. It is one of two living Baltic languages with an official status, the other being Lithuanian. The Latvian and Lithuanian languages have retained many features of the nominal morphology of Proto-Indo-European, though their phonology and verbal morphology show many innovations (in other words, forms that did not exist in Proto-Indo-European),For example the Latvian debitive verb form (man ir jāmācās “I must study” or “it is necessary for me to study”) and the Lithuanian frequentative past (jie eidavo “they used to go”).Baltic languages - Comparison of Lithuanian and Latvian , Encyclopedia Britannica with Latvian being considerably more innovative than Lithuanian. However, Latvian has mutual influences with the Livonian language.

History

Origins

According to some glottochronological speculations, the East Baltic languages split from West Baltic (or, perhaps, from the hypothetical proto-Baltic language) between 400 and 600 CE. The differentiation between Lithuanian and Latvian started after 800 CE. At a minimum, transitional dialects existed until the 14th century or 15th century, and perhaps as late as the 17th century.

Latvian as a distinct language emerged over several centuries from the language spoken by the ancient Latgalians assimilating the languages of other neighbouring Baltic tribes—Curonian, Semigallian, and Selonian—which resulted in these languages gradually losing their most distinct characteristics. This process of consolidation started in the 13th century after the Livonian Crusade and forced Christianisation, which formed a unified political, economic, and religious space in Medieval Livonia.

16th–18th century

The oldest known examples of written Latvian are from a 1530 translation of a hymn made by , a German in Riga. The oldest preserved book in Latvian is a 1585 Catholic catechism of Petrus Canisius currently located at the Uppsala University Library in Sweden.

The first person to translate the Bible into Latvian was the German Johann Ernst Glück (The New Testament in 1685 and The Old Testament in 1691). The Lutheran pastor Gotthard Friedrich Stender was a founder of Latvian secular literature. He wrote the first illustrated Latvian alphabet book (1787), the first encyclopedia "" (; 1774), grammar books and Latvian–German and German–Latvian dictionaries.

19th century Until the 19th century, the Latvian written language was influenced by German Lutheran pastors and the German language, because Baltic Germans formed the upper class of local society. In the middle of the 19th century the First Latvian National Awakening was started, led by "Young Latvians" who popularized the use of Latvian language. Participants in this movement laid the foundations for standard Latvian and also popularized the Latvianization of loan words. However, in the 1880s, when Czar Alexander III came into power, Russification started.

According to the 1897 Imperial Russian Census, there were 505,994 (75.1%) speakers of Latvian in the Governorate of Courland and 563,829 (43.4%) speakers of Latvian in the Governorate of Livonia, making Latvian-speakers the largest linguistic group in each of the governorates.

20th century

After the death of Alexander III at the end of the 19th century, Latvian nationalist movements re-emerged. In 1908, Latvian linguists Kārlis Mīlenbahs and Jānis Endzelīns elaborated the modern Latvian alphabet, which slowly replaced the old orthography used before. Another feature of the language, in common with its sister language Lithuanian, that was developed at that time is that proper names from other countries and languages are altered phonetically to fit the phonological system of Latvian, even if the original language also uses the Latin alphabet. Moreover, the names are modified to ensure that they have noun declension endings, declining like all other nouns. For example, a place such as Lecropt (a Scottish parish) is likely to become Lekropta; the Scottish village of Tillicoultry becomes Tilikutrija.

After the Soviet occupation of Latvia, the policy of Russification greatly affected the Latvian language. At the same time, the use of Latvian among the Latvians in Russia had already dwindled after the so-called 1937–1938 Latvian Operation of the NKVD, during which at least 16,573 ethnic Latvians and Latvian nationals were executed. In the 1941 June deportation and the 1949 Operation Priboi, tens of thousands of Latvians and other ethnicities were deported from Latvia. Massive immigration from the Russian SFSR, Ukrainian SSR, Byelorussian SSR, and other republics of the Soviet Union followed, primarily as a result of Stalin's plan to integrate Latvia and the other Baltic republics into the Soviet Union through colonization. As a result, the proportion of the ethnic Latvian population within the total population was reduced from 80% in 1935 to 52% in 1989. In Soviet Latvia, most of the immigrants who settled in the country did not learn Latvian. According to the 2011 census Latvian was the language spoken at home by 62% of the country's population.

After the re-establishment of independence in 1991, a new policy of language education was introduced. The primary declared goal was the integration of all inhabitants into the environment of the official state language while protecting the languages of Latvia's ethnic minorities.

Government-funded bilingual education was available in primary schools for ethnic minorities until 2019 when Parliament decided on educating only in Latvian. Minority schools are available for Russian, Yiddish, Polish, Lithuanian, Ukrainian, Belarusian, Estonian and Roma languages. Latvian is taught as a second language in the initial stages too, as is officially declared, to encourage proficiency in that language, aiming at avoiding alienation from the Latvian-speaking linguistic majority and for the sake of facilitating academic and professional achievements. Since the mid-1990s, the government may pay a student's tuition in public universities only provided that the instruction is in Latvian. Since 2004, the state mandates Latvian as the language of instruction in public secondary schools (Form 10–12) for at least 60% of class work (previously, a broad system of education in Russian existed).

Altogether, 2 million, or 80% of the population of Latvia, spoke Latvian in the 2000s, before the total number of inhabitants of Latvia slipped to 1.8 million in 2022.

The Official Language Law was adopted on 9 December 1999. Several regulatory acts associated with this law have been adopted. Observance of the law is monitored by the Latvian State Language Center run by the Ministry of Justice.

21st century To counter the influence of English, government organizations (namely the Terminology Commission of the Latvian Academy of Science and the State Language Center) popularize the use of Latvian terms. A debate arose over the Latvian term for euro. The Terminology Commission suggested or , with their Latvianized and declinable ending, would be a better term for euro than the widely used , while European Central Bank insisted that the original name euro be used in all languages. New terms are Latvian derivatives, calques or new loanwords. For example, Latvian has two words for "telephone"— and , the former being a direct translation into Latvian of the latter international term. Still, others are older or more euphonic loanwords rather than Latvian words. For example, "computer" can be either or . Both are loanwords; the native Latvian word for "computer" is , which is also an official term. However, now has been considered an appropriate translation, is also used.

There are several contests held annually to promote the correct use of Latvian. One of them is "Word of the year" () organized by the Riga Latvian Society since 2003. It features categories such as the "Best word", "Worst word", "Best saying" and "Word salad". In 2025 the word (wireless headphone) won the category of "Best word" and (to trigger) won the category of "Worst word". The word pair of (stream) and (streaming) were named the best words of 2017, while as an unnecessary plural of the name for transport was chosen as the worst word of 2017.

Dialects

There are three dialects in Latvian: the Livonic dialect, High Latvian and the Central dialect. Latvian dialects and their varieties should not be confused with the Livonian, Curonian, Semigallian and Selonian languages.

Livonic dialect

The Livonic dialect (also called Tamian or tāmnieku) of Latvian was more affected by the Livonian language substratum than Latvian in other parts of Latvia. It is divided into the Vidzeme variety and the Courland variety (also called tāmnieku). There are two syllable intonations in the Livonic dialect, extended and broken. In the Livonic dialect, short vowels at the end of words are discarded, while long vowels are shortened. In all numbers, only one form of the verb is used. Due to migration and the introduction of a standardised language, this dialect has declined. It arose from assimilated Livonians, who started to speak in Latvian.

Central dialect The Central dialect spoken in central and Southwestern Latvia is the basis of standard Latvian. The dialect is divided into the Vidzeme variety, the Curonic variety and the Semigallic variety. The Vidzeme variety and the Semigallic variety are closer to each other than to the Curonic variety, which is more archaic than the other two. There are three syllable intonations in some parts of Vidzeme variety of the Central dialect, extended, broken and falling. The Curonic and Semigallic varieties have two syllable intonations, extended and broken, but some parts of the Vidzeme variety have extended and falling intonations. In the Curonic variety, ŗ is still used. The Kursenieki language, a historic variety of Latvian, which used to be spoken along Curonian Spit, is closely related to the varieties of the Central dialect spoken in Courland.
