What are the rules for pronoun-antecedent agreement?

The rules for pronoun-antecedent agreement are as follows:

1. The pronoun must agree with its antecedent in number. For example, if the antecedent is singular, the pronoun should also be singular, and if the antecedent is plural, the pronoun should also be plural.

2. The pronoun must agree with its antecedent in gender. This means that if the antecedent is masculine, the pronoun should be masculine, and if the antecedent is feminine, the pronoun should be feminine.

3. The pronoun must agree with its antecedent in person. If the antecedent is in the first person (I, we), the pronoun should also be in the first person. If the antecedent is in the second person (you), the pronoun should also be in the second person. And if the antecedent is in the third person (he, she, it, they), the pronoun should also be in the third person.

4. The pronoun must agree with its antecedent in case. This means that if the antecedent is in the subjective case (I, he, she, they), the pronoun should also be in the subjective case. If the antecedent is in the objective case (me, him, her, them), the pronoun should also be in the objective case.

Overall, the key is to ensure that the pronoun matches its antecedent in number, gender, person, and case.
