+231.+ We often make mistakes in the use of the different forms of the
pronoun _who_. We often use the subject form for the object form, using
_who_ where we should have used _whom_. For example:
Who did you see?
The correct form is:
Whom did you see?
The pronoun _whom_ is the object of the verb _see_, hence the object
form should be used. However, the use of the subject form _who_ instead
of _whom_ is coming into such general use today that some grammarians
accept it as a permissible usage. The will of the people influences
language, as it does all other human institutions, and gradually creates
new rules.
Write three sentences, using _who_, _which_ and _what_ as interrogative
pronouns.
+An interrogative pronoun is a pronoun used to ask a question.+
