* Pronoun Case: Pronouns have different forms depending on their grammatical function in a sentence. The three main cases are:
* Nominative Case: Used for the subject of a verb (e.g., *I*, *we*, *he*, *she*, *it*, *they*, *who*).
* Objective Case: Used for the object of a verb or preposition (e.g., *me*, *us*, *him*, *her*, *it*, *them*, *whom*).
* Possessive Case: Shows ownership (e.g., *my*, *our*, *his*, *her*, *its*, *their*, *whose*).
* Grammatical Function: The role of a pronoun in a sentence determines which case is correct. For example:
* Subject: *He* went to the store. (Nominative case)
* Object: The dog chased *him*. (Objective case)
* Possessive: That is *her* book. (Possessive case)
Examples:
* Correct: *She* gave *him* the book. (*She* is the subject, *him* is the object)
* Incorrect: *Her* gave *he* the book. (Wrong cases for subject and object)
Remember: Pay attention to how the pronoun is used in the sentence to choose the correct case.
