What is the greek word for united?

There isn't one single perfect Greek word for "united" as the best translation depends on the context. However, here are a few options with slightly different nuances:

* ενωμένος (enōmenos): This is a common adjective meaning "united," "joined," or "combined." It's a good general-purpose option.

* ἑνωμένος (henōmenos): This is a less common variant of the above, with essentially the same meaning.

* ενωμένος (enōmenos) can also be used as a participle implying the act of unifying.

The best choice depends on whether you're talking about people, ideas, or things being united, and the nature of the union. You might need to add other words for more precision (e.g., "united in purpose" would require additional words).
