The Bulgarian language is a South Slavic language primarily spoken in Bulgaria. It is the official language of the country and is used by approximately 8 million people. Bulgarian uses the Cyrillic alphabet, which was developed in the 9th century and is also used by several other Slavic languages. Bulgarian is unique among Slavic languages due to its lack of noun cases, which simplifies grammar. It has a rich literary tradition, with notable works dating back to the Middle Ages. The language has also been influenced by Turkish, Greek, and Romanian due to historical interactions in the region.
