* "Makua hānai" - This literally means "nurturing father" and could be used to refer to a stepfather who has a close relationship with the child.
* "Ke kāne o ka makuahine" - This literally means "the husband of the mother," and is a more literal and neutral way to describe a stepfather.
* "Ka makua kāne o ka wahine" - This means "the father of the wife" and would be used when referring to the stepfather from the perspective of the spouse.
The best translation depends on the context and the specific relationship between the stepfather and the child.
