So imagine you have a toy, and it's your toy. You love your toy and you want to talk about it. When you talk about your toy, you might say "my toy" because it belongs to you. That's kind of like how we use a possessive antecedent in writing or talking.
A possessive antecedent is a special word that shows ownership or possession. It's usually used in a sentence to talk about something that someone has, like a toy or a book. For example, if you wanted to say that the toy belongs to you, you might say "my toy." And if you wanted to say that the book belongs to someone else, you might say "their book."
In writing, we use possessive antecedents to make our sentences more clear and specific. Without them, it might be hard to tell who owns what or who is in charge of something.
So remember, a possessive antecedent is like saying "my toy" instead of just "toy" to show it belongs to you. It helps us talk about who owns what so we don't get confused.
