Cyrillic script

Structure and characteristics

Cyrillic letters were modelled in part on Greek uncial shapes and on earlier local scripts. Alphabets that use Cyrillic may include modified letters, digraphs or diacritics to represent sounds absent in Greek. Most Cyrillic alphabets distinguish uppercase and lowercase forms and follow alphabetic ordering, but the exact inventory of characters varies by language.

History and development

The early form of the script emerged in the Balkans in the period following the missionary activity of Cyril and Methodius. Scholars attribute its formalization to disciples and scribes in medieval cultural centers such as those in the First Bulgarian Empire. Over many centuries the script spread with Orthodox Christianity and literacy, and it underwent national reforms to suit local phonologies and print technology; for example, Russia simplified letterforms in the early modern era.

Modern use and distribution

Today Cyrillic serves as the official or co-official script for a number of Slavic languages and for several non-Slavic languages. Notable modern users include:

• Russian
• Ukrainian
• Belarusian
• Rusyn
• Bulgarian
• Macedonian
• other South Slavic languages
• and many languages brought into Cyrillic use through Soviet policy in regions such as the Caucasus, Siberia, Central Asia and northern Russia.

Variants, reforms and computing

National alphabets differ: some add letters to represent local vowels and consonants, others eliminate obsolete signs. In the 19th and 20th centuries many reforms standardized spelling and reduced archaic letters. In the digital age Cyrillic is encoded in Unicode, enabling consistent use across computers and the internet while allowing for continued national orthographic variation.

Significance and distinctions

Cyrillic is more than a set of characters; it carries cultural and political significance in the countries that use it. In several places it coexists with Latin or Arabic scripts, and script choice can reflect historical ties, identity and practical needs for communication and administration. Understanding Cyrillic therefore involves orthography, history and sociolinguistics as well as paleography and typographic design.
