Let me explain:
* Pronoun: A word that replaces a noun (e.g., he, she, it, they, yours, mine).
* Possessive pronoun: A type of pronoun that shows ownership or possession (e.g., mine, yours, his, hers, its, ours, theirs).
So, possessive pronouns are a specific subcategory of pronouns, just like personal pronouns (I, you, he, she, etc.) and demonstrative pronouns (this, that, these, those).
