“Case” refers to the different types of functions or positions that pronouns can fulfill within a sentence. Pronouns can be subjects or objects, and they can also show possession. It is important to use the right case so that subjects and verbs agree in number and gender within the sentence, pronouns and antecedents agree in number and gender, and the pronouns show the correct relationship (i.e. possessive or non-possessive). Using the wrong pronoun case will make your writing sound awkward and more difficult to read.
Subjective Case: Pronouns that function as the subject of the sentence (or phrase, or clause) appear in the subjective case.

Objective Case: Pronouns that function as the object of the sentence (or phrase, or clause) appear in the objective case.

Possessive Case: Pronouns that show possession or ownership appear in the possessive case.
