Questions & Answers about Ha inventato una scusa quando ha capito che ci saremmo arrabbiati.
Why do we use the past conditional (saremmo arrabbiati) here instead of the present conditional?
This is the 'future in the past'. When you are talking about a past event ('he understood') and refer to something that was in the future at that moment ('we would get angry'), Italian requires the past conditional. English just uses 'would' plus the base verb, but Italian needs this specific compound tense.
Why is the auxiliary verb saremmo used instead of avremmo?
The verb for 'to get angry' is arrabbiarsi, which is a reflexive verb (notice the pronoun ci). In Italian, all reflexive verbs must use essere as their auxiliary in compound tenses like the past conditional.
Why does arrabbiati end with an -i?
