What does Lillian translate to in Greek?

There isn't a direct, established Greek equivalent for the name Lillian. Greek names don't typically have a direct one-to-one translation with names from other languages.

Some possibilities, depending on the nuance you'd like to convey, might include:

* Λείλα (Leila): While Arabic in origin, it has a similar sound and also connects to night and beauty.

* Κρίνος (Krinos): This means "lily" in Greek, but it's masculine. A feminine variation might be needed.

* Καλλιρόη (Kallirhoe): This name means "beautiful flow" or "beautiful stream" and evokes a sense of grace and beauty.

* Άννα (Anna): While not directly related to lily, Anna has a similar delicate and classic feel.
