Romania is not considered a Slavic country primarily because of its linguistic and historical background. The Romanian language is a Romance language, which means it evolved from Latin, the language of the Roman Empire. This is in contrast to Slavic languages, which belong to the Indo-European language family but evolved from a different branch.
Historically, Romania was part of the Roman Empire, and the region was heavily influenced by Roman culture and language. After the Roman Empire’s influence waned, the area that is now Romania was subject to various invasions and migrations, but the Latin-based language persisted and evolved into what is now known as Romanian.
Additionally, Romania’s geographical location played a role in its cultural and linguistic development. Situated in Southeastern Europe, Romania is surrounded by Slavic-speaking countries, but it has maintained its Romance language identity. This is partly due to the Carpathian Mountains, which provided a natural barrier that helped preserve the Latin-based language and culture.
In summary, Romania is not Slavic because its language and cultural heritage are rooted in the Roman Empire, distinguishing it from the Slavic nations that surround it.
