Old East Slavic


Old East Slavic, traditionally known as Old Russian (Russian: древнерусский), is a name for a vernacular literary language used between the 10th and 14th centuries by East Slavs in Kievan Rus and other states formed by that ethnic group. Its dialects were spoken, though not exclusively, roughly in the area today occupied by the European part of Russia, Belarus, Ukraine and several eastern voivodships of Poland.
