Lithuanian (lietuviu kalba) is the official state language of Lithuania and is recognized as one of the official languages of the European Union. There are about 2.9 million native Lithuanian speakers in Lithuania and about 200,000 abroad. Lithuanian is a Baltic language, partially related to Latvian, however they are not considered mutually intelligible. It is written in a Latin alphabet. The Lithuanian language is often said to be the most conservative living Indo-European language, retaining many features of Proto-Indo-European now lost in other Indo-European languages.
