Here are a few options depending on the context:
* "Aliʻi wahine" (ah-lee-ee vah-hee-neh) - This literally translates to "noble woman" and could be used to refer to a princess.
* "Keiki aliʻi" (kay-kee ah-lee-ee) - This means "royal child" and could also be used to refer to a princess.
* "Mōʻī wahine" (moh-ee vah-hee-neh) - This means "queen" and could be used to refer to a princess in some contexts.
Ultimately, the best way to express "princess" in Hawaiian would depend on the specific situation and who you are speaking to.
