I was prompted to do a Google search about this topic. I found this post from English Forums that talks about a very similar sentence:
http://www.englishforums.com/ShowPost.aspx?PostID=13921.
Quote:To understand this well, convert the 'whomever' into 'any person who'
But, I decided to search a bit more. I found this website:
http://members.rogers.com/scripta-word-services/article-moregrammar.html.
Quote:Is it "whoever" or "whomever"? First create the statement:
_____ comes first.
"He" makes sense here, so use whoever:
Give the trophy to whoever comes first.
So, now I was confused, since I had found documentation supporting both options, although the internet is often unreliable. I decided to break out my brand new Chicago Manual of Style and look up usage notes for "who" and "whom." (My American Heritage Dictionary has usage notes, but they weren't very clear.)
Quote:whoever; whomever. Avoid using the second unless you are certain of your grammar {give this book to whoever wants it} {give it to whomever you choose}. If you are uncertain why both these examples are correct, use anyone who in the first example and just anyone in the second.
Letty, the "special case" that you remembered actually appears to be the correct one, for the exact reason you stated. "Who," in berm's sentence, is the subject of a clause and is the proper choice.
I went back and read my dictionary once more:
Quote:In certain constructions involving a choice between who and whom, the pronoun is often miscontrued as the object of a verb when in fact it is the subject of the clause: He interviewed a girl who he thinks will be excellent in the role
I knew that the example sentence in this quote was the correct way to phrase it, but I neglected to apply this rule to the sentnece given by berm.
I believe that berm was describing this certain case earlier, but I had believed before that "whomever" would always be used when following a preposition, but I was in fact incorrect. There is this special case where "to whoever" is the proper term.
So, Letty, berm, thanks for offering the debate and prompting me to research this topic more fully. I can proudly say that I learned something new today; and, even better, something about grammar, a topic about which I love learning new things!
