Russian (Russian: русский язык, romanized: russkij jazyk, Russian: [ˈruskʲɪj jɪˈzɨk]) is an East Slavic language mainly spoken across Russia. It is the native language of the Russians, and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages. Besides Russia itself, Russian is an official language in Belarus, Kazakhstan, and Kyrgyzstan, and is used widely as a lingua franca throughout Ukraine, the Caucasus, Central Asia, and to some extent in the Baltic states. It was the de facto language of the former Soviet Union, and continues to be used in public life with varying proficiency in all of the post-Soviet states.
