Fun fact, Niʻihau is a protected island where a Hawaiian family has lived for many years. It's often called the forbidden island. There are no roads or commercial buildings, and food is obtained by hunting and gathering. The people there speak Hawaiian. https://www.hawaii.com/discover/island-of-niihau/
It is only "protected" in the sense that it is private property, right? Since the owners of the island are the Robinsons, descendants of the Sinclairs, I assume that, while Hawaiian, some of their ancestors came from the British Isles.
That's how I understand it. They bought it for $10,000 in the 1860s so going there without permission would be trespassing.
Wow, $10,000 was a fortune for a private person.
Is there a more formal term for mother?
