Who versus Whom

<p>Hey, I notice this is on a lot of questions, What is the best way to decide if the correct usage is who or whom in a particular sentence.</p>

<p>Correct me if I am wrong but who is used if its the subject and whom is used if its the object.</p>

<p>You're right! Who is subjective and whom is objective.</p>

<p>With whom (whom is the object of the preposition with) and I speaking?
Who (who acts the subject of the sentence) said that?</p>

<p>Who is going on the trip? They are going.
To whom does this belong? It belongs to them.</p>

<p>There are many threads on this. Please use the search function.</p>
