Questions & Answers about La madre viste al niño.
Because Spanish often uses the personal a before a specific human direct object.
Here, el niño is the person receiving the action of vestir. So Spanish adds a:
- La madre viste a el niño → this contracts to La madre viste al niño
So al here is just a + el.
Important: in this sentence, a does not mean to. It is just marking the boy/the child as a person who is the direct object.
