Two Classes of Possessives, Kino ʻŌ and Kino ʻĀ

In Hawaiian there are two classes of possessives, (Kino ʻŌ and Kino ʻĀ).

(Kino ʻŌ) items ,in general, are things you do not have control over, in terms of creating them, like your ancestors, parents, siblings, and body parts.

Things that you possess for the purpose of wearing them, or primarily to be situated in, on, under, behind, or in front of are

also (kino ʻŌ), like clothes, shelter, buildings, time, land, and modes of transportation.

All the other items, those that you have the ability to create or choose are (Kino ʻĀ) . Like your spouse, your children, food, your job, and other things you create like songs you write, or art you make.
