The pronoun 'whom' is an interrogative pronounand a relative pronoun.
The pronoun 'whom' is used for the object of a verb or a preposition.
The corresponding subject interrogative and relative pronoun is 'who'.
An interrogative pronoun introduces a question. Examples:
Subjective: Who gave you the book?
Objective: To whom will you give the book? (object of the preposition 'to')
A relative pronoun introduces a relative clause (a group of words with a subject and a verb that gives information about its antecedent). Examples:
Subjective: The one who gave the party was my neighbor.
Objective: The one from whom I received an invitation was my neighbor. (object of the preposition 'from')
"Whom's" is not a standard word in English. The proper form to use is "whom," which is the objective case of "who."
with whom
Proper nouns
The pronoun 'whom' is an objective case, relative pronoun; a pronoun that introduces a relative clause. For example: To whom do I own the money for my sandwich? (whom is object of the preposition 'to') Whom did you see at the mall today? ('you did see whom at the mall', object of the verb 'see') Because the proper use of 'whom' is confusing and when used correctly, sounds awkward, very few people use the word in written text. As a relative pronoun, whom can be replaced by who. eg My daughter Nina, whom (who) you met last year, is getting married tomorrow. Whom is rarely used now because it is too formal, in any sentence who is now preferred over whom.
To whom it may concern
The basic rule is this: Use the pronoun "who" when it is the subject of a clause and use "whom" when it is the object of a clause.Probably 90% of the places where you need to use "whom" are prepositional phrases. It's always "to whom", "from whom", "on whom", "with whom", "over whom", "of whom", since "whom" is the object of the preposition.If you are using the pronoun as the subject of the sentence, use "who". It's always, "Who is", "Who went", "Who did", "Who came", "Who left",Here's a trick to help remember: It's the same as the difference between "he" and "him". If a reply to your sentence would use "he", then your sentence should use "who"; if a reply to your sentence would use "him", then your sentence should use "whom". (Remember that "whom" and "him" both end with 'm'.) For example,"Who made this mess?" "He made this mess.""Who drove the car?" "He drove the car.""To whom did you give the keys?" "I gave them to him.""From whom did you hear that rumor?" "I heard it from him."Here's a tricky one--the subject is "you" and the object is "whom", but they're turned around:"Whom did you hit with a snowball?" "I hit him."
and whom may i be talking to
Use their names ie Dear Tess and Mike, If you don't know their names To whom it may concern: works
For whom the bell tolls.
It depends in the placement in the sentence (and possibly the formality of the conversation). "Who" is the subjective form; meanwhile, "whom" is the objective form. In proper writing, for instance, it is correct to put "For whom is the present?". Colloquially, it is instinctive to say, "Who is this present for?". The first example is correct in proper grammar (In proper writing, never end a sentence in a preposition e.g. for, from, to, at, before, etc.). As mentioned earlier, "who" is the subjective form. For example, "Who is it at the door?" or "Who is calling me at this hour?" are both examples of the subjective case. Basically, if it is a subject in a normal, declarative sentence, then you say "who." If it is in a prepositional phrase, or if it is a direct/indirect object, then you use "whom." More examples: "For whom are you giving this?" "This is for *name*." "To whom are you talking?" "I am talking to my imaginary friend." "Who ever can it be?" "It's your creepy stalker!" "Who will come to the party?" "No one will come to the party."
You can use both who and whom you trust. Who can be used as a subject and an object of a clause, but not object of a preposition. Whom can only be used as an object. She is the one who is always there for me. (not whom because who is the subject of is) _She is the only one who (_or whom) I trust. (object of trust) She is the one on whom (not who) I can rely . (object of the preposition on)
'Whom' is used as the object of a sentence, typically following a preposition or a verb. Use 'whom' when referring to the object of a verb or a preposition, while 'who' is used as the subject. For example, you would say "To whom did you give the book?" because 'whom' is the object of the preposition 'to.'
