Formal:
* Aloha ʻāina: This means "love for the land" and can be used as a farewell when leaving a place, especially if it has been meaningful to you.
* A hui hou: This literally means "until we meet again" and is a common and polite farewell.
* Mahalo nui loa: Means "thank you very much" and can also be used as a farewell, especially when expressing gratitude for the time spent together.
Informal:
* E komo mai: Means "come in" but is often used as a way of saying "goodbye" in a friendly way.
* A hui hou, ʻoe: This adds a personal touch to "A hui hou" and means "until we meet again, you".
For a more poetic farewell:
* Ke aloha iā ʻoe: Means "the love is with you".
The best option depends on the specific situation and the desired level of formality.
