Ukrainian language

Ukrainian /jˈkrniən/ (About this sound listen) (українська мова ukrajinśka mova) is an East Slavic language. It is the official state language of Ukraine and first of two principal languages of Ukrainians; it is one of the three official languages in the unrecognized state of Transnistria, the other two being Romanian and Russian. Written Ukrainian uses a variant of the Cyrillic script (see Ukrainian alphabet).

Historical linguists trace the origin of the Ukrainian language to the Old East Slavic of the early medieval state of Kievan Rus'. After the fall of the Kievan Rus' as well as the Kingdom of Galicia–Volhynia, the language developed into a form called the Ruthenian language. The Modern Ukrainian language has been in common use since the late 17th century, associated with the establishment of the Cossack Hetmanate. From 1804 until the Russian Revolution, the Ukrainian language was banned from schools in the Russian Empire, of which the biggest part of Ukraine (Central, Eastern and Southern) was a part at the time. It has always maintained a sufficient base in Western Ukraine, where the language was never banned, in its folklore songs, itinerant musicians, and prominent authors.

The standard Ukrainian language is regulated by the National Academy of Sciences of Ukraine (NANU), particularly by its Institute for the Ukrainian Language, Ukrainian language-information fund, and Potebnya Institute of Language Studies. The Ukrainian language retains a degree of mutual intelligibility with Belarusian and Russian.
