The Cyrillic script is an alphabet used for various languages across Eastern Europe and Central Asia. It was developed in the 9th century by the disciples of Saints Cyril and Methodius, who sought to create a writing system for the Slavic peoples. The script has evolved over time and now includes letters that represent sounds specific to different languages. Today, the Cyrillic script is the basis for several languages, including Russian, Bulgarian, and Serbian. It consists of 33 letters in the Russian version, with some variations in other languages. The script is known for its distinctive characters, which differ significantly from the Latin alphabet.
