What does joey mean in greek?

"Joey" is not a Greek name and doesn't have a direct Greek meaning. It's an English name, likely a shortened form of "Joseph."

However, "Joseph" does have a Greek origin and meaning:

* "Joseph" (Ιωσήφ, Iōsēph): Means "God will increase" or "God will add."

So while "Joey" itself doesn't have a Greek meaning, it's derived from a name with a strong Greek connection.
