<p>What's the difference? Enlighten me</p>

<p>Wow, a grammar question I can answer.</p>

<p>Who's = Who is, as in, Who's at the door?
Whose = possessive, as in, Whose book is this?</p>

<p>ok I was overthinking lol. thanks</p>

<p>What about whom?</p>

<p>Who and whoever are subjective, whom and whomever are objective.
Who goes with he/she. ex: Jones is the man whom I went fishing with last spring. (I went fishing with him.)
Whom goes with him/her. ex: Joyce is the girl who got the job. (She got the job.)
Not the greatest examples (I took them from a website (<a href="http://web.ku.edu/%7Eedit/whom.html%5B/url%5D"&gt;http://web.ku.edu/~edit/whom.html&lt;/a&gt;); I'm new to who/whom as well), but they will suffice.</p>

<p>Whom is a lot easier than people think - Whenever you're presented with who/whom, just think to yourself: if it were he vs. him, which would I use in this sentence? If it's he, use who; if it's him, use whom.</p>

<p>EDIT: Why I wrote that out when the poster above me explained it just as well I have no idea. lol.</p>
