The Baltic languages are a group of related languages belonging to the
Indo-European language family and spoken mainly in areas extending east and southeast of the
Baltic Sea in
Northern Europe. The language group is sometimes divided into two sub-groups: Western Baltic, containing only extinct languages, and Eastern Baltic, containing both extinct and the two living languages in the group:
Lithuanian (including both Standard Lithuanian and
Samogitian) and
Latvian (including both literary Latvian and
Latgalian). While related, the Lithuanian, the Latvian, and particularly the
Old Prussian vocabularies differ substantially from each other and are not mutually intelligible. The now extinct Old Prussian language has been considered the most archaic of the Baltic languages. Some linguists connect this group with the group of
Slavic languages. Lithuanian is supposed to be one of the most archaic and least changed conservative Indo-European language.
