The indirect object indicates the person or thing receiving the action of the verb. They can be replaced by the indirect object pronouns me, te, le, nos, os, les. The indirect object answers the question “to whom?” or “for whom?”.
Mi novia me compró un reloj.
My girlfriend bought me a watch.
indirect object pronoun - me
Unlike English, Spanish also requires the indirect object pronoun when the indirect object is still present in the sentence.
Yo le di el dinero a Juan ayer.
I gave the money to Juan yesterday.
indirect object - Juan
indirect object pronoun - le (to him)
Pedro me da el dinero.
Pedro gives me the money. ¿Qué te dijo ella?
What did she tell you? Ellos nos lo dieron.
They gave it to us. Todos los dias le doy cuerda a mi reloj.
I wind my watch every day.
Indirect object pronouns can also go after the verb: Déjame presentarte a Susana.
Let me introduce you to Susana. Juan, dile a María que nosotros no podemos ir antes de las tres.
Juan, tell Maria that we can't come before three.
