Pronombre de complemento indirecto

Spanish indirect object pronoun

See also: Pronombre and Pronoun types

Indirect object pronouns usually replace people (or other living things) that are introduced after the verb with a preposition (a or para). They indicate the person who the action of the verb is destined to or for.

Juan trajo unas flores a Ana.
Juan brought Ana some flowers.

Juan le trajo unas flores.
Juan brought her some flowers. (To whom? To Ana).

Mi madre ha comprado un regalo para mí.
My mum has bought a present for me.

Mi madre me ha comprado un regalo.
My mum has bought me a present. (For whom? For me).

Note that the preposition disappears when you use the pronoun.

Warning: Not all prepositions introduce an indirect object! Indirect objects are specifically the ones that the verb is doing something to or for.
