The words who, whom and whoose are pretty confusing to me. Who is quite commonly use. But I don't understand and know when should be the correct situation these words are used. This is especially for whom.
For example,
Who was the one.
Whoose pencil does it belongs to?
To whom it may concern.
To whom do you wish to speak?
All these are what we, or at least I, commonly hear. But what about in more intricate sentences? Can I have some examples?
This this sentence correct: Whoever he knows are people whom he wish to meet.
But it sounds the same if I change whom to who.

Hope somebody could clear my doubts on this who whom thing... thanksEmotion: smile

There is no word call whoose. It should be whose.

There is a pencil on the table.

Whose pencil is it?

To say 'whose pencil does it belongs to' is not necessary. It is just verbose.

To whom it may concern is a standard set of words people use when writing a certificate or something similar. I wouldn't argue about it.

Who was the one/person you met in town yesterday. This is fine.


Whom is the objective form of who, used when who is not the subject of its own clause.

My wife can't remember whom she saw in town.

Whom did you say you had seen?

It was formally considered correct to use whom whenever the objective form of who was required. Not any longer.
