What is the country that owns demonym of Aramaic?

The demonym "Aramaic" is not associated with a specific country. It refers to the Aramaic language and its speakers, who historically lived in a vast region stretching from modern-day Turkey to Egypt, including parts of Syria, Iraq, Lebanon, Jordan, and Israel.

Therefore, there is no single country that "owns" the demonym Aramaic. It is a historical and cultural term encompassing a diverse group of people and communities.
