(LAUGHING) --- I've tried to use them correctly but I finally gave up as I couldn't remember which one was proper to use at which time. Darn! (+Pts.2.U.)

If I'm remembering correctly, whom is only used when speaking about a singular male. For example: if your girl friend was speaking of a man she may be seeing: "And whom might this be?" Otherwise, it would be who.

Who wrote the greeting; "To whom it may concern," on this letter?

he = who him = whom

Yes, I do. I started typing a nerdy explanation, but then I realized you probably don't care that much. :) So, I'll just say this: use 'whom' when you are referring to the object of the sentence; use 'who' when you are referring to the subject. Who cheated whom? Who is the man whom they believe to be the spy?

Who said, "To whom are you referring?"

Sure. "Who" is a subject pronoun. "Whom" is an object pronoun. "A person who downrates someone just for disagreeing doesn't care whom he offends."

Whom is an object pronoun. Who is a subject pronoun.

Are you the language police? Is there a prize if I get it right? :(

"Who said what to whom?"

From: http://web.ku.edu/~edit/whom.html Three “easy-to-use” rules so you'll always get it correct Rule #1: Substitute “he/him” or “she/her”: If it's either “he” or “she,” then it's “who;” if it's “him” or “her,” then it's “whom.” Rule #2: Every verb with a tense in a sentence must have a subject. And that word is always in the nominative case, so it's “who.” For example: In this sentence, “I decided to vote for whoever called me first”: • “I” is the subject of “decided” • “he” (whoever) is the subject of the verb “called.” In the sentence, “Give it to whoever deserves it”:([You] give it to whoever deserves it.) • “he” (whoever) is the subject of the verb “deserves.” This rule supersedes the first rule as it relates to “who” and “whom.” Note: Related to this rule is one that says: The subject of a phrase is always attached to that phrase — no matter what. For example: Ask whoever reads that book to answer the question. Break down the sentence thusly: (You) ask him (he reads that book) to answer the question. In the phrase “he reads that book,” you cannot separate the subject “he” from the phrase to which it is attached. If you remember these two rules — substitute “he/him” or “she/her,” and that every verb with a tense must have a subject — you should solve the “who/whom” quandary every time. If you apply those two rules and you're still not sure, apply the all-important Rule #3. Rule #3: Give it a sincere and honest effort to determine if it's “who” or “whom.” If it takes more than a 30 seconds to figure it out, pick the one that sounds best to the ear (read it aloud) and move on. Why? Because even grammarians are likely to squabble over which to use. But always — always — apply rules #1 and #2 before using Rule #3. --------------------------------------------------------------------------------

The difference is subject and object. yes I know. I'll show you too. "I want to speak to whoever is running for office." Not whomever, because the it acts as the subject of that clause. "Whom do you want to win?" Object form here because "You" is the subject.

Who is active and whom is passive. Who did it, and to whom?

i ask men often who is hunting whom.

Who is subjective Whom is objective Who did what to whom
