Here are some options, depending on what aspect of "soul" you want to express:
* ʻUhane: This word is often translated as "spirit" and refers to the immaterial part of a person, often associated with the breath. It can also be used for the soul, particularly in a spiritual context.
* ʻAumakua: This word refers to a family guardian spirit, often an ancestor or animal that watches over and protects a family lineage. It could be interpreted as a spiritual connection to one's ancestral lineage.
* Mana: This term refers to a supernatural power or energy that resides in people, objects, or places. It can be seen as an internal power that connects us to something greater, which could be interpreted as a facet of the soul.
Ultimately, the best Hawaiian translation for "soul" will depend on the specific context and meaning you want to convey.
