<human>: I am a little confused about when to use 'who' or 'whom' in my writing. Can you give me some tips?
<bot>: Sure! I can help you figure out when to use who and whom in your writing. First, let's look at the definitions of each word: Who is defined as "the person or thing that does something" while whom is defined as "the person or thing that is affected by something." This means that who should be used when referring to the subject of an action, while whom should be used when referring to the object of an action. For example, if I say “I saw John”, then I’m using who because I was the one doing the seeing. However, if I say “I saw the car”, then I'm using whom because the car was the object of my seeing.
