Combined pronouns are created when an indirect object pronoun (mi, ti, gli, le, ci, vi) and a direct object pronoun (lo, la, li, le) appear together in the same sentence. They replace both objects to avoid repetition.

For example:
"Mi dai il libro?" "Certo, te lo do subito".→ Do you give the book to me? Sure, I give it to you right away.
"Chi vi ha dato i biglietti?" "Ce li ha dati Marco" → Who gave you the tickets? Marco gave them to us.
"La macchina è mia e non voglio prestartela" → The car is mine and I don't want to lend it to you

As it happens with direct object pronouns, the participio passato of the verbs agree with the combined pronoun (-o, -a, -i, -e):
"Roberta mi ha chiesto dei libri e glieli ho prestati".


In case of a modal or phrasal verb (volere, potere, dovere, sapere, cominciare a, stare per, finire di) followed by an infinitive, the combined pronoun can either be used before the verb or after the infinitive:
"La bicicletta mi serve, non te la posso prestare"
"La bicicletta mi serve, non posso prestartela"

When a reflexive pronoun and a direct object pronoun are in the same sentence, they join up to form a double object pronoun. When this happens, the -i of the reflexive pronoun changes to -e.

For example:
"Devo farmi una doccia"→ "Me la devo fare"
"Vi ricordate le sorelle Bianchi?" → "Ve le ricordate?"
"Devi lavarti i capelli" → "Devo lavarteli"

The imperative is used to give orders or advice.

For example:
"Lava i piatti" → Wash the dishes
"Spegni la tv" → Turn off the TV
"Aprite la porta" → Open the door
