Formal:
* Aloha ʻoe (ah-loh-hah oh-eh) - This is the most common and widely recognized phrase, meaning "farewell to you." It's often used as a general goodbye, similar to "goodbye" in English.
* A hui hou (ah hoo-ee how) - This means "until we meet again." It's a slightly more formal farewell, implying that you expect to see the person again.
* Maikaʻi (my-kah-ee) - This means "good" or "well." It can be used as a simple goodbye, especially in a more casual setting.
Informal:
* Aloha (ah-loh-hah) - This can be used as both a hello and a goodbye, and is a very common greeting.
* E komo mai (eh koh-moh my) - This literally means "come in," but it's also used as a way of saying "see you later" or "stay well."
The best way to choose the right phrase is to consider the situation and your relationship with the person you are saying goodbye to.
