* Greece (Ελλάδα): The most obvious example, derived from the ancient Greek word "Hellas."
* Italy (Italia): The origin is debated, but a strong theory links it to a pre-Roman Oscan word which may itself be derived from a Greek word meaning "calf-land" (referring to cattle).
* Bulgaria: The name is ultimately derived from the ancient Thracian tribe of the Bulgars. While not directly Greek, the name's transmission and evolution involved interactions with the Greek world.
* Georgia (Sakartvelo): The ancient Greek word for this region was "Iberia". The modern name "Georgia" is a later derivation, but the underlying geographical name has its roots in Greek contact.
* Turkey (Türkiye): Though the modern name is Turkish, the ancient Greek name for the region, Asia Minor, reflects Greek presence and naming conventions.
It's important to note that the connection isn't always straightforward. Many names have evolved over centuries through various languages and cultures, making direct lineage difficult to trace with certainty in all cases. The influence of Greek is often more subtle than a direct etymological match.
