* οικογένεια (oikogeneia): This is the most common and generally accepted translation for "family" in modern Greek. It refers to the nuclear family (parents and children) or the extended family, depending on the context.
* οίκος (oikos): This word means "house" or "household," and in a broader sense, it can refer to the family that lives within that house. It's a more classical and less frequently used term in modern Greek for the concept of "family" itself.
* συγγενείς (syggeneis): This word means "relatives" or "kin." It refers to a wider range of family members beyond the immediate nuclear family.
Therefore, οικογένεια (oikogeneia) is the best general translation, but consider συγγενείς (syggeneis) if you want to emphasize the extended family or relatives. οίκος (oikos) is more appropriate in historical or literary contexts.
