Russian alphabet it is- 33 letters;
- some letters can denote several sounds
- and some - do not have sounds.
Slavic, or Old Slavonic writing ("glagolitsa") originated in 863 in Bulgaria, when two brothers Cyril and Methodius created the Slavic alphabet for translating church books from the Greek language. The Slavic alphabet ("cyrillic alphabet") consisted 43 letters - 24 Greek letters and 19 new letters. How the alphabet looked in 9th century you can see here >>
In the Ancient Rus alphabet appeared in the late 10th century, when the Russians adopted Christianity, and from that time the history of the Russian alphabet begins. :)
In the process, the Russian alphabet was transformed:
- in 1708 and 1710, the times of Peter I, 7 extra letters were removed and were added "Я" and "Э", a civil font appeared (for printing secular publications);
- in 1735, the times of Anna Ioannovna, they removed 3 letters and added "Й";
- in 1758, the times of Peter III, was returned letter "I";
- in 1783, the times of Catherine II, appeared letter "Ё";
- in 1918 the last major reform of the Russian alphabet took place. Basically, it changed the spelling of some letters and removed "Ъ" at the end of the words.
Thus, in the Russian alphabet 33 letters, 10 letters denote vowel sounds and 21 - consonants, and 2 letters ("ъ" - a hard sign and "ь" - a soft sign) do not designate special sounds. The Russian alphabet has large (uppercase) and small (lowercase) letters, as well as printed and handwritten ones.
And since 1863 in Russia there was a holiday - the Day of Slavic writing and culture, or the day of Saints Cyril and Methodius - May 24.
