Short history of the Russian language

The sixth century AD saw the migration of the Slav people from old Poland. The Slavs expanded westwards to the river Elbe and southwards to the Adriatic sea where they gradually occupied much of the Balkans. By the tenth century, three Slavonic language groups had emerged: Western, Southern and Eastern. Eastern Slavonic gave rise to the modern languages known as Ukranian, Belorussian and Russian. The Slavonic languages retained many features in common especially in grammatical structure, therefore the separate groups were able to use one common written language. This language was known as Old Slavonic or Old Church Slavonic (the language was used in its written form only). In the ninth century, two missionaries - Constantine (who on his deathbed took the monastic name Cyril) and Methodius - were required to write down the scriptures in Old Church Slavonic and to preach Christianity to the people of Moravia. Before they set out for Moravia, Constantine invented a Slavonic, now known as the Cyrillic alphabet. The Cyrillic alphabet is closely based on the Greek alphabet, with about a dozen additional letters invented to represent Slavic sounds not found in Greek.

In Russia, Cyrillic was first written in the early Middle Ages in clear-cut, legible ustav (large letters). Later a succession of cursive forms developed. In the early eighteenth century, under Peter the Great, the forms of letters were simplified and regularized, with some appropriate only to Greek being removed. Further unnecessary letters were expunged in 1918, leaving the alphabet as it is today.

In Russia, Old Church Slavonic remained the written language until the middle of the eighteenth century. By this time, the need was felt for a written language which was closer to the educated spoken norm. The famous M. V. Lomonosov, after which the Moscow State University is named, distinguished three styles:

1) High Style - Church Slavonic, to be used for poetics and religion.
2) Middle Style - to be used for lyric poetry, prose and science.
3) Low Style - to be used in personal correspondence and in low comedy.

The Middle Style, which combined features of both East Slavonic and Church Slavonic is the style which came to form the basis of the modern standard language. In the mid 1800's, Standard Russian based on the Moscow dialect became the official language. Today Russian is the most important of the Slavic languages and is now one of the major languages of the world. It is also one of the official languages of the United Nations. In a recent census, 153 million people listed Russian as their mother tongue and another 61 million indicated they spoke it fluently as a second language. The number of Russian speakers world-wide could be in the region of 220 million.

The Russian language allows an interesting way of addressing people to whom you have just been introduced. The person's first name is combined with a modified form of his or her father's first name. If a man's first name is Ivan and his father's first name is also Ivan, you would call him Ivan Ivanovich (Ivan, son of Ivan), and if Ivan had a sister, she would be called Natasha Ivanovna, (Natasha, daughter of Ivan). The -ovich and -ovna suffixes are always appended to the father's first name and not to the mother's.

Saints Cyril and Methodius Day

In Russia, it is celebrated on 24 May and is known as the "Slavonic Literature and Culture Day" (Russian: День славянской письменности и культуры), celebrating Slavonic culture and literature as well as the alphabet. Its celebration is ecclesiastical (11 May on the Church's Julian calendar), and it is not a public holiday in Russia.

The brothers Cyril and Methodius are most renowned for the development of the Glagolitic alphabet that was used to bring literacy and Christian literature to the Slavs in their own language. With further development by their disciples it became the Cyrillic alphabet, which is now used by many of the Slavic peoples. However, the work of the brothers in translating the Holy Scriptures, the services, Nomocanon, and other Christian literature into Slavonic has been the greatest example of Orthodox missionaries bringing Christianity to the peoples of the world.

While events only a few decades after the death of Methodius seemed to destroy their work in Moravia, their work became the foundation of Slavic civilization in eastern and south-eastern Europe and provided the language footings for the missionary efforts in the coming centuries. It is this continuation of the practice of the Holy Apostles of speaking of Christianity in the languages of all the nations that Ss Cyril and Methodius are remembered as equal to the apostles.
