I passed the ball to him.
Here, is "to him" modifying the object "ball" or the action verb "passed"? How can we know for sure?
I have been to several websites before I come here. I did practice to distinguish between adverbial and adjectival prepositional phrases, but I am still not very clear. (If I ask "Who am I passing the ball to?", it feels like "to him" tells us more information about who I am passing the ball to, which would make "to him" an adjective phrase. However, I can also see "to him" as giving more information about the ball, that the ball is going "to him", making it an adjective).
