What is the greek word for go?

There isn't one single Greek word for "go" as the best translation depends on the context. Here are a few options with slightly different meanings:

* Πηγαίνω (pinaíno): This is the most common and versatile word, generally meaning "to go" or "to be going."

* Υπάγω (ypágo): This implies "to go under," "to submit," or "to undergo," so it's not a direct equivalent in all situations.

* Περπατώ (perpató): This means "to walk," so it's appropriate if "go" implies walking.

* Φεύγω (févgo): This means "to leave" or "to depart," implying a more definite departure.

The best choice will depend on the specific nuance you want to convey.
