<p>No matter how many times I look this up, it seems I still can't quite grasp it. Or rather I think I do, but a few days later I end up missing it again. </p>
<p>I know that you use who for subject and whom for object, but how do you clearly determine if it is a subject/object?</p>
<p>Ex: Give the letter to ____ answers the door. </p>
<p>The correct answer is whoever, but isn't it an object because you're giving the letter to HIM, so therefore whomever? </p>
<p>Or this one:</p>
<p>The wealthy socialite decided that her fortune would be left to (whomever) of her relatives could present her with the best plan for dispensing part of the money to deserving charities. </p>
<p>The correct answer is whoever, but I thought it'd be whomever as she's giving the money to the relative, meaning the socialite is the subject and the receiver is the object. </p>
<p>I'm getting these questions from Grubers SAT writing workbook, by the way. </p>
<p>If anyone could explain this to me I'd be extremely grateful.</p>
