Latvian language
Latvian ("Latviešu valoda" ) is a Baltic language spoken in the Baltic region. It is the language of Latvians and the official language of Latvia as well as one of the official languages of the European Union. It is sometimes known in English as Lettish, and cognates of the word remain the most commonly used name for the Latvian language in Germanic languages other than English. There are about 1.3 million native Latvian speakers in Latvia and 100,000 abroad. Altogether, 2 million, or 80% of the population of Latvia, speak Latvian. Of those, 1.16 million or 56% use it as their primary language at home. The use of the Latvian language in various areas of social life in Latvia is increasing.
Lithuanian language
Lithuanian is one of two living Baltic languages, along with Latvian. An earlier Baltic language, Old Prussian, was extinct by the 18th century; the other Western Baltic languages, Curonian and Sudovian, became extinct earlier. Some theories, such as that of Jānis Endzelīns, considered that the Baltic languages form their own distinct branch of the family of Indo-European languages, but the most widely accepted opinion is the one that suggests the union of Baltic and Slavic languages into a distinct sub-family of Balto-Slavic languages amongst the Indo-European family of languages. Such an opinion was first represented by the likes of August Schleicher, and to a certain extent, Antoine Meillet. Endzelīns thought that the similarity between Baltic and Slavic was explicable through language contact while Schleicher, Meillet and others argued for a genetic kinship between the two families.
