In short: Developed at the Preslav Literary School, the Bulgarian Cyrillic alphabet replaced the earlier Glagolitic script. It has served as the foundation for numerous Slavic languages, including Russian and Ukrainian. Today, it remains a dynamic system, continuously adapting to modern technology and the influx of global loanwords into Bulgarian.

The Cyrillic alphabet emerged in the First Bulgarian Empire during the 9th and 10th centuries. Officially adopted in 893, it eventually superseded the Glagolitic alphabet, which had been devised by Saint Cyril and Saint Methodius. From Bulgaria, the script spread to Kievan Rus' and evolved into the various alphabets used by East Slavic languages today. Throughout its history, the script has undergone significant modifications, including the 1945 orthographic reform that removed the archaic letters yat and yus, settling the alphabet at its current 30-letter count.

Bulgarian orthography is largely phonemic, meaning words are generally spelled as they are pronounced. However, this system includes specific nuances, such as the use of the letter ь to soften preceding consonants and the letter ъ to represent the back vowel /ɤ/. While the language has historically borrowed terms from French and German, the post-communist era has seen a surge in English computer-related terminology. These neologisms are often integrated phonetically into Bulgarian sentences, though some media outlets now occasionally retain original English spellings for abbreviations and brand names.

The script's influence extends beyond national borders; upon Bulgaria's accession to the European Union on 1 January 2007, Cyrillic became the EU's third official script, alongside Latin and Greek. Despite its ancient origins, the alphabet remains highly adaptable. Modern speakers frequently use both traditional Bulgarian terms and English-derived loanwords, demonstrating the script's flexibility in a digital age. Whether through the official 'Streamlined System' of transliteration or the informal adoption of tech jargon, the Bulgarian alphabet continues to bridge the gap between its historical roots and contemporary global communication.
