Pronoun case

How do you know which pronoun to use when referring to subjects, objects, or showing possession?

As the Purdue Online Writing Lab (Purdue University, n.d.) describes,

Pronouns take three forms:

  1. Subjective case: pronouns used as subject.
  2. Objective case: pronouns used as objects of verbs or prepositions.
  3. Possessive case: pronouns which express ownership.


Pronouns as subjects Pronouns as objects Pronouns that show possession
I me my (mine
you you your (yours)
he, she, it him, her, it his, her (hers), it (its)
we us our (ours)
they them their (theirs)
who whom whose

The pronouns thisthatthesethose, and which do not change form. (para. 1)

For more information regarding subjects and objects within a sentence, please refer to the appropriate information within Sentence Elements.
