Options might include:
* Άγγελος (Angelos): This is the Greek word for "angel," but it's masculine. You could use it as inspiration for a similar-sounding name, perhaps a feminine variation if one exists in usage.
* Αγγελική (Angeliki): This is a common Greek feminine name derived from "angelos" and means "angelic." This is probably the closest and most natural-sounding equivalent.
Therefore, while there's no direct translation, Αγγελική (Angeliki) is the best and most commonly used Greek equivalent for the name Angela.
