The Baltic languages, part of the Indo-European family, include Latvian and Lithuanian. These languages are known for their preservation of many archaic features not found in other Indo-European languages. Estonian belongs to the Finnic branch of the Uralic language family, which is distinct from Latvian and Lithuanian. The Baltic languages are part of the Indo-European language family, whereas Estonian, along with Finnish and other Finnic languages, belongs to a different language family altogether.
