* "Kāne" is a very general term, so it's not as specific as "husband."
* "Kāne" can also refer to a male deity.
A more specific translation would be "kāne i ka wahine", which literally means "man to the woman." This more accurately conveys the relationship between a husband and wife.
Ultimately, the best way to say "husband" in Hawaiian depends on the context and what you want to convey.
