Double interrogative pronoun is ?
Answers
We use interrogative pronouns to ask questions. They are: who, which, whom, what and whose. These are also known as wh-words. Questions using these are called wh-questions:
Who called last night?
Which keys are yours?
Whom do I ask for at the desk?
What did you do when the electricity failed?
Whose watch is this?
Interrogative pronouns: uses
We use who and whom on their own:
Who paid?
Whom did you speak to?
We can use whose, which and what either on their own (as pronouns) or with a noun head (underlined): in the above pic..
Warning:
We use whom as an object in formal styles. When we use a preposition before whom, it is even more formal. We don’t normally use it in speaking:
Whom did you give the book to? (formal)
To whom did you give the book? (very formal) Or, less formally: Who did you give the book to?
