what is the difference between Interrogative Pronouns and interrogative adjectives.
An interrogative pronoun is a pronoun used in order to ask a question. Often it has no antecedent because the antecedent is unknown. That is why the question is being asked!
In modern English there are five interrogative pronouns:
what, which, who, whom, and whose.
Note that all five words may also be used as relative pronouns. A relative pronoun may be found in a question; an interrogative pronoun is found only in a question.
In addition, these pronouns may take the suffixes -ever and -soever.
As their name suggests, interrogative adjectives are those adjectives that are used in questions. In Spanish, they take the same form as the interrogative pronouns, although only a few of the pronouns can be used as adjectives.
