Only two parts of speech, nouns and pronouns, have case. This means that they change form depending on how they are used in a sentence. English has three cases: nominative, objective, and possessive.
In the nominative case, the pronoun is used as a subject.
· I threw the ball.
In the objective case, the pronoun is used as an object.
· Give the ball to me.
In the possessive case, the pronoun is used to show ownership.
· The ball is mine.
The following chart shows the three cases of personal pronouns:
