* Aloha ʻoe: This is the most famous Hawaiian phrase and means "goodbye to you," but it also carries a deep meaning of love, affection, and respect. It's often used as a more general expression of love, similar to "I love you" in English.
* Mahalo nui loa: This means "thank you very much" and can be used to express deep gratitude and appreciation for someone you love.
* Ke aloha wau iā ʻoe: This is a more literal translation of "I love you" and is a good choice for expressing romantic love.
* Hauʻoli wau iā ʻoe: This means "I'm happy with you" and can be used to express a strong sense of love and contentment.
Ultimately, the best way to say "I love you" in Hawaiian will depend on the specific situation and the relationship between the people involved.
