Cyrilic alphabet (Кириллица азбука)
I have found an interesting topic to talk about now that recently I have studied briefly the subject religion in my class. I could not understand why all these countries have in common the same religion, some superstitions or letters in their their alphabet. Doing this research, made me have a clearer idea and I hope it helps you as well.
The cyrilic alphabet used by Russians and other Slavic languages like Serbian, Macedonian, Ukranian, Belarus among others, was created by monks based on the Greek alphabet, because the Greek monks brought to Russia the orthodox religion and with it its writing.
This alphabet has letters that represent sounds which do not exist on Greek. It was named like this due to its creator, the monk Cyril who translated the Bible from Greek to Russian in 827 to 869 a. C.
The alphabet had 24 letters and 12 more to represent sounds that were not on Greek or Latin.
In the 6th century, several Slavic tribes started a journey to what today is Ukraine and the South of Russia, they split directions and in the next centuries those nations battled to turn the barbarians into their religion. The Byzantine emperor sent missionaries to those countries, so they could teach them to read and then turn them into orthodox church.
When can say that the Cyrillic script was an indirect result of the missionary work of the 9th-century Apostles of the Slavs, St. Cyril and St. Methodius over 40 years, it is said that they created it in Bulgaria. The Slavic languages were richer in sounds than Greek and 43 letters were originally provided to represent them; the added letters were modifications or combinations of Greek letters based on Hebrew such as ts, sh, and ch. The earliest literature written in Cyrillic was translations of parts of the Bible and various church texts.
The modern Cyrillic alphabeth have been modified; modern Russian has 33 letters with inclusion of the soft sign, Bulgarian 30, Serbian 30, Ukranian 33, etc.
