his choosing vs. his being chosen
This is a practice drill from the free 52-lesson Tongan course. The course reaches for it in lesson 29, the possessive system in full, where it runs inside the lesson as well as on this page, rated advanced.
ʻene fili (he does it) vs. hono fili (it's done to him).
Every item asks the same thing: Doer or receiver? Each item shows a line of Tongan and a short row of answers to tap. Right or wrong, the drill then says why that answer is the one the grammar wants.
One from the deck: ʻeku tokoni. The answers offered are I do it, done to me.
