* Ωραίος (ōraios): This is a common and versatile word, generally meaning "beautiful," "handsome," or "lovely." It can be used for both people and things. It's a good general-purpose choice.
* Καλός (kalós): This word means "good," "fine," "beautiful," or "handsome." Its meaning is broader than "ōraios," encompassing more than just aesthetic beauty. It can also describe moral goodness.
* Ευπρεπής (euprepēs): This word signifies "well-formed," "elegant," or "graceful." It implies a more refined and sophisticated kind of beauty.
* Αισθητικός (aisthētikós): This means "aesthetic," referring to a sense of beauty or appreciation for art. It wouldn't be used to describe a person directly as beautiful, but rather their appreciation for beauty.
* For a woman specifically, you might also use όμορφη (ómorthi), which is the feminine form of a word related to "beautiful," but less common than the others.
The best word to use will depend on what you're describing and the specific type of beauty you want to convey. For most situations, Ωραίος (ōraios) or Καλός (kalós) will be suitable.
