"Hers" is a possessive pronoun used to indicate ownership or belonging. It refers to something that belongs to a female person or animal. For example, if a girl has a book, one might say, "That book is hers." This pronoun helps to clarify who owns the item without repeating the person's name. In English grammar, "hers" functions as a possessive adjective and can be used in various contexts. It is often used in sentences to emphasize possession, such as "The decision was hers." This usage helps to highlight the individual's role or authority in a situation, making it clear that the ownership is specifically attributed to her.
