(who,whom)____ will the choir director choose?
http://grammar.ccc.commnet.edu/grammar/pronouns.htm#who
the answer, i think, is who
The correct word to use in the given sentence is "whom." The sentence will be: "Whom will the choir director choose?"
To determine whether to use "who" or "whom" in a sentence, you need to understand the difference between the two.
"Who" is used as the subject of a verb or as a subject complement. It refers to the person performing the action. For example, "Who will go to the party?" or "She is the one who won the award."
"Whom" is used as the object of a verb or a preposition. It refers to the person receiving the action. For example, "Whom did you invite to the party?" or "He is the person to whom I spoke."
Now, let's apply this knowledge to the given sentence: "(Who, whom) will the choir director choose?"
In this case, we are discussing the person receiving the action of being chosen by the choir director. Since "whom" is used for objects, the correct word to use in this sentence is "whom." Therefore, the correct sentence would be: "Whom will the choir director choose?"
Remember, you can use the technique of replacing "who" or "whom" with the pronoun "he" or "him" to test which one is correct. In this case, "He will the choir director choose?" doesn't sound right, whereas "Him will the choir director choose?" sounds better. Thus, "whom" is the correct choice.
