What is the greek word of link?

There isn't one single perfect Greek word for "link" as the meaning depends on the context. However, depending on what kind of link you mean, several words could be used:

* Σύνδεσμος (sýndesmos): This is probably the closest general equivalent. It refers to a connection, bond, or link, often in a physical or figurative sense. This would be a good choice for many uses of the English word "link."

* Κρίκος (kríkos): This means "ring" or "link" specifically in the sense of a chain or ring-shaped connector.

* Σύνδεσμος (sýndesmos) again, but with more context, could be used for a hyperlink in digital media. You might need to add descriptive words to clarify the meaning.

Therefore, Σύνδεσμος (sýndesmos) is the most versatile and likely the best single word choice, but the best translation always depends on the specific context.
