Bulgarian language

The Bulgarian language is an Indo-European language that originated from Proto-Slavic. Proto-Slavs inhabited parts of Europe in the 1st century AD but dispersed across a large territory starting in the 4th century AD, contributing to differences between Slavic languages. However, Bulgarian and other Slavic languages like Russian, Polish, and Serbian still retain common features from their Proto-Slavic roots that make them analogous. Specific characteristics of Bulgarian include having definite articles at the end of words and unique sounds like ъ and ДЖ.
