Formal:
* Mahalo nui loa: This is the most formal and respectful way to say "thank you very much."
* Mahalo nui: This is slightly less formal than "mahalo nui loa," but still very respectful.
Informal:
* Mahalo: This is the most common way to say "thank you."
* Mahalo ʻoe: This is a slightly more personal way to say "thank you."
You can also add "ke akua" (to God) or "iā ʻoe" (to you) after "mahalo" to make it more specific:
* Mahalo ke akua: Thank you, God.
* Mahalo iā ʻoe: Thank you to you.
It's important to remember that the Hawaiian language is very nuanced, and the best way to say "thank you" will depend on the specific situation.
