Personal pronouns have nunbers person and what?

Personal pronouns have three main features: number, person, and case. "Number" refers to whether the pronoun is singular (referring to one) or plural (referring to more than one). "Person" indicates the perspective of the pronoun, which can be first person (the speaker), second person (the listener), or third person (someone or something being talked about). "Case" determines the pronoun's grammatical role in a sentence, such as nominative (subject), accusative (object), or genitive (possessive).
