‘Who’ or ‘whom’?
There’s an ongoing
debate in English about when you should use
who and when to use
whom. According to the rules of
formal grammar,
who should be used in the
subject position in a sentence, while
whom should be used in the
object position, and also after a
preposition.
In questions
Who made this decision? [here,
who is the subject of the sentence]
Whom do you think we should support? [here,
whom is the object of
support]
To whom do you wish to speak? [here,
whom is following the preposition
to]
In practice, most people never use
whom like this in speech because it sounds extremely
formal. They don't use
whom at all, and instead use
who in all contexts, i.e.:
Who do you think we should support?
Who do you wish to speak to?
