In writing, WHO is used for the subject of a verb and WHOM is used for the object of a verb or a preposition. For example: Who is the person to whom I speak? The -m of whom is the same as the -m of him, the sign of the objective case in 3rd person pronouns.
In speech, whom is all but obsolete.
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)
The answer is whom. If you can replace it with he or she it's who, if it's him or her it's whom.
How about, Who was this done by? or you might have to use "Whom". Can't remember which one.
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."
The relative pronoun 'who' is the subjective form which functions as the subject of a relative clause.The relative pronoun 'whom' is the objective form which functions as the object of a preposition.Examples:My mom is the one who made the cake. (subject of the relative clause)The one for whom she made it is my grandma. (object of the preposition 'for')
Ok - this is quite an easy one to remember. You use 'who' when the people that you are talking about are the object of your sentence and "whom' when they are the subject of your sentence. If you get confused, you can use a simple trick... If you can put HE or SHE in the place of who/whom, then you should use...WHO. Example: Bill, who was the boss of the company. He was the boss of the company. So, WHO is correct. If the sentence only makes sense with HIM or HER, then use WHOM. Example: John, whom she met at school. If you put HE in this type of sentence it looks silly...She met HE at school. So, it must be....She met HIM at school...so use WHOM.
Assuming you know how to use other pronouns correctly... Use "who" where you would use "he" and "whom" where you would use "him." More formally, "who" is the subjective form (i.e. the one used when it's the subject of a sentence) and "whom" is the objective form (the one used when it's the object of the sentence). "whom" is gradually disappearing in favor of "who" in all cases. Much the same thing happened to "you" a couple of centuries ago... at one time, "you" was the objective form only, with the subjective form being "ye" (to make it even more confusing, "you/ye" was originally plural and/or formal; the singular familiar form was "thee/thou").
Yes, that is one use of the objective case "whom" (the subjective is "who"). Many times, however, colloquial use will separate the preposition and the wrong case will be used.Examples:"We did not know to whom the package should be addressed.""Ask not for whom the bell tolls.""With whom was he travelling when the accident happened?"(the incorrect form Who was he travelling with? is very common)
and whom may i be talking to
When the person referred to is the OBJECT of a sentence, or following a preposition - places, that is, where the Accusative case is required. The person to whom I gave the present The person whom I contacted yesterday
For whom the bell tolls.
'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.'
