Point out the pronouns in the following sentences, that are used in
asking questions:—
1. Who did this?
2. What are you going to do next?
3. Which of the boys lost his knife?
A pronoun that is used in asking a question is called an =interrogative
pronoun=; as, _Who_ gave you the orange?
The interrogative pronouns are _who_, _which_, and _what_.
_Who_ and _which_ are declined like the relatives.
_Who_ refers to persons; _which_ refers to persons or to things; _what_
refers to things.
_Note._—_Which_ differs from _who_ in being selective; as, _Which_ of
the books is yours?
