Think of it like this: the pronoun is a stand-in for something already mentioned. The antecedent is the original thing that the pronoun is replacing.
Example:
* "The dog wagged its tail."
Here, the pronoun "its" refers to the antecedent "dog."
Here are some key points to remember:
* Pronouns must have clear antecedents: It's important for the reader to be able to easily understand which noun the pronoun refers to.
* Antecedents should be close to their pronouns: This helps avoid confusion.
* Pronouns and antecedents must agree in number and gender: If the antecedent is singular, the pronoun should be singular. If the antecedent is feminine, the pronoun should be feminine, etc.
