A report on Russian language and Cyrillic script

Both schools originally used the Glagolitic alphabet, though the Cyrillic script developed early on at the Preslav Literary School, where it superseded Glagolitic as official in Bulgaria in 893.

Significant later recensions of Old Church Slavonic (referred to as Church Slavonic) in the present time include: Slovene, Croatian, Serbian and Russian.

Written Ukrainian uses the Ukrainian alphabet, a variant of the Cyrillic script.

Comparisons are often drawn to Russian, a prominent Slavic language, but there is more mutual intelligibility with Belarusian, Ukrainian's closest relative.

Of these, 10 have at least one million speakers and official status as the national languages of the countries in which they are predominantly spoken: Russian, Belarusian and Ukrainian (of the East group), Polish, Czech and Slovak (of the West group) and Bulgarian and Macedonian (eastern dialects of the South group), and Serbo-Croatian and Slovene (western dialects of the South group).

The most obvious differences between the East, South, and West Slavic branches are in the orthography of the standard languages: West Slavic languages (and Western South Slavic languages – Croatian and Slovene) are written in the Latin script, and have had more Western European influence due to their proximity and speakers being historically Roman Catholic, whereas the East Slavic and Eastern South Slavic languages are written in Cyrillic and, with Eastern Orthodox or Uniate faith, have had more Greek influence.

Old East Slavic (traditionally also Old Russian; старажытнаруская мова; древнерусский язык; давньоруська мова) was a language used during the 10th–15th centuries by East Slavs in Kievan Rus' and its successor states, from which the Belarusian, Russian, Rusyn, and Ukrainian languages later evolved.

Although the Glagolitic alphabet was briefly introduced, as witnessed by church inscriptions in Novgorod, it was soon entirely superseded by Cyrillic.

Before Belarus gained independence in 1991, the language was only known in English as Byelorussian or Belorussian, the compound term retaining the English-language name for the Russian language in its second part, or alternatively as White Russian.

The Belarusian alphabet is a variant of the Cyrillic script, which was first used as an alphabet for the Old Church Slavonic language.

The modern Cyrillic script is still used primarily for some Slavic languages (such as Bulgarian, Macedonian, Serbian, Russian and Ukrainian), and for East European and Asian languages that have experienced a great amount of Russian cultural influence.

A major event was the development of the Cyrillic script in Bulgaria at the Preslav Literary School in the 9th century.

During the seventeenth and eighteenth centuries, it was gradually replaced by the Russian language in secular literature and was retained for use only in church.

Until 1945, Bulgarian orthography did not reveal this alternation and used the original Old Slavic Cyrillic letter yat (Ѣ), which was commonly called двойно е (dvoyno e) at the time, to express the historical yat vowel or at least root vowels displaying the ya – e alternation.

Rusyn, also known by the older term, , is an East Slavic language spoken by Rusyns in several parts of Central and Eastern Europe, and written in the Cyrillic script.

Some linguists claimed that East Slavic dialects of the Carpathian region should be classified as specific varieties of the Russian language.

Bulgaria was instrumental in the spread of Slavic literacy and Christianity to the rest of the Slavic world.

Standardised Slavic languages that have official status in at least one country are: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Macedonian, Montenegrin, Polish, Russian, Serbian, Slovak, Slovene, and Ukrainian.
