Are greek and spanish the same?

No, Greek and Spanish are not the same language. They are from completely different language families:

* Greek belongs to the Indo-European language family, specifically the Hellenic branch.

* Spanish belongs to the Indo-European language family, specifically the Romance branch.

While both languages share some common roots due to being Indo-European, they have distinct vocabularies, grammar, and pronunciations. You wouldn't be able to understand someone speaking one language if they were speaking the other.
