Double Object Pronouns

Me lo, Te lo, Nos lo

At times both a direct and indirect object pronoun will appear in the same sentence.  NOTE: When that happens, the indirect object pronoun always precedes the direct object pronoun.  (me lo, te lo, nos lo)

Direct object with a ponoun:

Juan me lo dijo.

Juan told it to me.

María nos los enseño.

Mary showed them to us.

Juan te lo explicó.

Juan explained it to you.

WITH Commands:

¿Lo que le pasó?   Sí, lo sé.  What happened?  Yes, I know it.
¿Quién te lo dijo?   No me lo dijo nadie. Who told you? No one told me anything.
¿Quién te compró la blusa?  Mamá me la compró. Who bought you the blouse?  Mama bought it for me.

Se lo

The indirect object pronouns lo and les both change to se when used with the direct object pronouns lo, los, la, las.   Since the pronoun se can have so many meanings, it is often clarified by the use of a prepositional phrase.

Él se lo dice a él (a ella, a Ud., a ellos, etc.). 
He tells it to him (to her, to you, to others, etc.)

Ellos se la explican a él (a ella, a Ud., a ellos, etc.)
They explain it to him. (to her, to you, to them, etc.)
