A personal pronoun is a word that replaces a specific noun, usually referring to people or things. Common examples include I, you, he, she, it, we, and they. These pronouns help avoid repetition in sentences, making communication smoother and clearer. Personal pronouns can indicate different grammatical categories, such as person (first, second, or third), number (singular or plural), and gender (masculine, feminine, or neutral). For instance, he and she are third-person singular pronouns that refer to male and female subjects, respectively, while we is a first-person plural pronoun used to refer to a group that includes the speaker.
