Here's a breakdown:
* Historically: Greeks are primarily associated with Greece, as that's where their ancient civilization originated and where the majority of Greeks reside today.
* Modern times: While the vast majority of Greeks live in Greece, there are significant Greek diaspora communities around the world. These individuals hold nationalities of their respective countries of residence (e.g., American, Canadian, Australian, etc.) while still maintaining a strong Greek identity.
So, to answer your question:
* If you're asking about the origin and primary location of the Greek people, then Greek is the answer.
* If you're asking about the nationality of individual Greeks, then the answer is dependent on their country of residence.
Hope this clarifies!
