Lithuanian (lietuvių kalba) is an Eastern Baltic language belonging to the Baltic branch of the Indo-European language family.
Lithuanian is closely related to the neighbouring Latvian language, though the two languages are not mutually intelligible, both written in a Latin script. In some respects, some linguists consider it to be the most conservative of the existing Indo-European languages, retaining features of the Proto-Indo-European language that had disappeared through development from other descendant languages.
