Indeed it does.


It's all to do with the subject and object of the sentence. For instance...

1)"He gave the apple to me."
In this sentence, "he" is the subject, and "me" is the object.

2) "I gave the apple to him."
Here, "I" is the subject, and "him" is the object.

In each case, the subject is the one giving the apple, and the object is the one they're giving the apple TO.

So... going by my helpful listy things...

1) "Who gave the apple to him?"
2) "He gave the apple to whom?"

"Who" is the subject; "whom" is the object.


In the same way...
"It's a present from him."
"It's a present from whom?"

"This chair is for me."
"This chair is for whom?"

"I threw a cushion at him."
"Who threw a cushion at him?"
"At whom did I throw the cushion?"

In each case, the sentence is about the subject ("who") and not so much about the object ("whom").
