Formal:
* Ka wahine ʻōpio: This translates literally to "young woman" and is a more formal way to refer to a young girl.
* Ke kaikamahine liʻiliʻi: This is a more literal translation of "little girl," but it might sound a bit awkward in everyday conversation.
Informal:
* Keiki wahine: This means "girl child" and is a more common way to refer to a young girl, especially in a playful or affectionate way.
* ʻOihana liʻiliʻi: This means "little one" and is a very general term that can be used for a young girl or boy.
You can also use the word kaikamahine on its own, which means "girl," and add a descriptive adjective like liʻiliʻi (little) or ʻōpio (young) to clarify the age.
Ultimately, the best way to say "little girl" in Hawaiian depends on the situation and your relationship with the person you're talking to.
