When should the personal a be used in a sentence, and why? Write your answer in English. Next, write a complete sentence in Spanish that uses the personal a.

The personal "a" should be used in a sentence when a direct object is a specific person or, occasionally, a specific pet. It is used to indicate that the action of the verb is being performed on that person or pet. The personal "a" helps distinguish between the subject and the object of the sentence and shows respect towards the object. It is not used for inanimate objects or for non-specific people.
