Lithuanian (lietuvių kalba) is a Baltic language and a component of the Indo-European language family. As their mother tongue, it is spoken by around 3 million people and is one of the official languages in Lithuania. It is also spoken by Lithuanian communities in other countries such as Poland, Latvia, Belarus, the USA, Canada and Great Britain.

The Lithuanian vocabulary has both Baltic and Indo-European influences. Throughout history, Lithuania has been influenced by different cultures and languages, which has led to words from German, Polish, Russian and other languages being incorporated into the Lithuanian vocabulary.

The Lithuanian alphabet is based on the Latin alphabet and comprises a total of 32 letters, including diacritical marks such as "č", "ę", "ė", "š" and "ž".

Lithuanian culture is also rich in traditions, folklore, music and literature. Lithuania has an ancient singing tradition and is known for its Lithuanian folk songs (dainos) and choirs. Lithuania celebrates traditional festivals such as Independence Day, Labor Day and Lithuanian Language Day. These festivals are linked to national identity, culture and history.
