In addition to the commonly used and known “Personal Pronouns”, there are 4 more categories of pronouns which we can use to demonstrate, to interrogate, to relate and in indefinite form. They are as follows:-

1. Demonstrative Pronouns (this, these, that, those)
A demonstrative pronoun identifies a noun or a pronoun.
  • this, that - will identify noun or pronoun in singular form.
  • these, those - will identify noun or pronoun in plural form.
  • this, these - to refer to objects that are nearby.
  • that, those - to refer to objects that are farther away.
e.g. This is good but that is not suitable/These are good but those are not suitable.
2. Interrogative Pronouns
  • (who, whom, which, what)
  • (whoever, whomever, whichever, whatever) - compounds formed with suffix “ever”
An interrogative pronoun is used for asking questions, or to inquire.
  • who, whom and sometimes which are used to refer to people
  • Whom did you speak to about our problems?
  • Which boy did you give the chocolates to?
  • Who is taking the blame?
3. Relative Pronouns
  • (who, whom, that, which)
  • (whoever, whomever, whichever) - compounds
A relative pronoun is used to link one phrase/clause to another.
