Who vs. Whom

This is a quick post that's mainly for myself. Today I had reason to check when to use "who" and when "whom", and found this very helpful trick:

     Like "whom," the pronoun "him" ends with "m." When you're trying to decide whether 

     to use "who" or "whom," ask yourself if the answer to the question would be "he" or "him."

     That's the trick: if you can answer the question being asked with "him," then use "whom," 

     and it's easy to remember because they both end with "m." For example, if you're trying to 

     ask, "Who (or whom) do you love?" The answer would be "I love him." "Him" ends with 

     an "m," so you know to use "whom."

     But if you are trying to ask, "Who (or whom) stepped on Squiggly?" the answer would 

     be "He stepped on Squiggly." There's no "m," so you know to use "who."

Makes sense to me!
