The Lithuanian language is a Baltic language spoken primarily in Lithuania. It is one of the oldest languages in Europe, retaining many features of Proto-Indo-European, the ancestor of many modern languages. Lithuanian has a rich system of inflection, which means that the endings of words change to express different grammatical functions. Lithuanian is the official language of Lithuania and is used in government, education, and media. It has two main dialects: Aukštaitian and Samogitian. The language uses the Latin alphabet and has 32 letters, making it unique among the languages of the region.
