"He let us in."

Translation: Lui ci ha fatto entrare.

[philipr]

I wrote "Lui ci ha lasciati entrare." I thought that if there was a clitic pronoun then the passato prossimo was declined like it. Is that only true if the main verb is "to be"?

[Saveriovp]

This tense is passato remoto, which i wish we were at least introduced to before this

[fificat1]

how were we supposed to know this?
