who and whom

[seal!]

what is the difference between who and whom? I've never been quite sure when to use which one (if that make sense).

[mac309]

According to my dictionary Who is the subject and whom is the object. eg. Who wrote the letter, and to whom is it addressed?

To add just a little to Mac's answer, treat 'who' and 'whom' in exactly the same way as you treat 'he' and 'him' or 'she' and 'her'. So, "He kicked the ball"...ie 'he' is the one doing the action of kicking...compared with "The dog bit him"...ie the person is the one having the action of biting done to him. Thus, "Who gave you this?" as compared with "By whom was this given to you?"

[hertz]

To take this a little further, one thing that gets up my nose is so many people - including professional journalists who, one may think, would know better - saying "I" instead of "me". Example - "Answers to this question have been provided by Quizmonster and I" instead of "me". As with who and whom. it's a case of mixing up subject and object.

The absolutely worst example of the sort of thing you're referring to, Hertz, is: "Between you and I", in my opinion.
