Interrogative Pronouns are one of the seven types of pronouns. Pronouns which help to introduce/ask questions are called Interrogative pronouns.
Who, which, what, whose, whom (whom is the subject form of who) and how are Interrogative pronouns.
All interrogative pronouns begin with ‘Wh’. But, one should know that although words like where, why and when start with wh- they are not Interrogative pronouns.
We should note that these pronouns also can take suffix –ever. Whatever, whichever, whoever etc. are few such examples. Suffix is added to show emphasis or surprise.
These pronouns represent our queries and help to get answers.
Sometimes, Interrogative pronouns (whose, which and what) also act as determiners when they are followed by nouns. Determiners are words functioning in a noun phrase to identify a referent that is denoted without describing or modifying it. Therefore, at times when these interrogative pronouns act as determiners they are called Interrogative adjectives. Interrogative pronouns introduce noun clauses and play a subject role in the clauses they introduce.
The main five Interrogative Pronouns are:
We should know that all these five words can also be used as relative pronouns. A relative pronoun can be found both in a statement and a question unlike an interrogative pronoun which can only be found in a question. Therefore, sentences having interrogative pronouns always end in question marks. Also, all these five words can be used as both subject and object.
