Indirect Object Pronouns
Indirect Object Pronouns are used as the indirect objects of verbs. As with direct object pronouns, they are required when the indirect object is a pronoun (in contrast to a noun) but a prepositional phrase may be added for clarification or emphasis.
¿Me hablas? - Are you talking to me?
¿Me hablas a mí? - Are you talking to me? [a mí added for emphasis]
Le dije la verdad. - I told him/her/you the truth.
Le dije la verdad a ella. - I told her the truth. [A ella added for clarification since le can mean “him” or “you”.]
¿A quién hablas? ¿A mí? - Who are talking to? (To) Me?
Sí, a tí. - Yes, (to) you.
