* Hīmeni: This is the most common and general way to say "sing," often referring to singing a hymn or spiritual song.
* Hī: This is a more general term for "singing" and can be used for any kind of singing.
* Oli: This word refers to a specific type of chanting or song, often used in traditional Hawaiian ceremonies or storytelling.
* Leo: This word literally means "voice" but can also be used to refer to singing.
The best choice will depend on the specific situation. If you're talking about singing a hymn, "hīmeni" is the best choice. If you're talking about singing in general, "hī" or "leo" could both work. And if you're referring to a traditional Hawaiian chant, "oli" is the most appropriate word.
