Samoan culture doesn't have a royal hierarchy or titles like "princess" in the European sense.
However, you could use the following terms depending on the context:
* Tupu" - This word means "chief" and is used for both men and women. It could be used to refer to a woman of high rank.
* Ali'i" - This word also means "chief" and is used for both men and women. It could also be used to refer to a woman of high rank.
* Tamaitai" - This word means "lady" and is a more general term that could be used for any woman of high standing.
* Fa'afine" - This term is used for a woman of high status, particularly in traditional settings. It can imply a woman of noble lineage.
Ultimately, the best way to refer to a "princess" in Samoan would depend on the specific situation and the cultural context.
