The sole official language of Latvia is Latvian, which belongs to the Baltic language sub-group of the Balto-Slavic branch of the Indo-European language family. Another notable language of Latvia is the nearly extinct Livonian language of the Finnic branch of the Uralic language family, which enjoys protection by law; Latgalian – as a dialect of Latvian is also protected by Latvian law but as a historical variation of the Latvian language. Russian, which was widely spoken during the Soviet period, is still the most widely used minority language by far (in 2011, 34% spoke it at home, including people who were not ethnically Russian).
