Overview
Lithuanian is an Eastern Baltic language belonging to the Baltic branch of the Indo-European language family. It is the official language of Lithuania and one of the official languages of the European Union. There are approximately 2.8 million native Lithuanian speakers in Lithuania and about 1,000,000 speakers elsewhere. Around half a million inhabitants of Lithuania of non-Lithuanian background speak Lithuanian daily as a second language.
Lithuanian is closely related to neighbouring Latvian, though the two languages are not mutually intelligible. It is 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.
History
Among Indo-European languages, Lithuanian is conservative in some aspects of its grammar and phonology, retaining archaic features otherwise found only in ancient languages such as Sanskrit (particularly its early form, Vedic Sanskrit) or Ancient Greek. For this reason, it is an important source for the reconstruction of Proto-Indo-European despite its late attestation (with the earliest texts dating only to 1500).
