With personal pronouns, a person establishes:
- case: This relates to the grammatical function of the pronoun in a sentence (e.g., subject, object).
- gender: Pronouns can indicate the gender of the person being referred to (e.g., he, she, they).
- number: Pronouns can be singular or plural, indicating whether they refer to one person or multiple people.
- point of view: This determines the perspective from which a statement is made, such as first person (I, we), second person (you), or third person (he, she, they).
So all of the options you provided are indeed established through personal pronouns.
