Questions & Answers about Ha promesso che avrebbe giustificato il ritardo, ma ha mentito.
Why do we use the past conditional (avrebbe giustificato) here instead of a future tense?
This sentence uses a structure called the "future in the past." Because the main action happened in the past (ha promesso), the action that was supposed to happen after it must be in the past conditional. You cannot use the regular future tense if the main reporting verb is already in the past.
In English, "would justify" looks like the present conditional. Can I use giustificherebbe here?
No, and this is a common trap! While English uses "would" plus a verb to show the future in the past, Italian strictly requires the past conditional (an auxiliary verb like avrebbe plus a past participle). You cannot use the present conditional here in Italian.
Ha promesso is from the verb promettere. Why isn't the past participle "promettuto"?
Promettere (to promise) has an irregular past participle: promesso. This is a handy pattern to remember, as most Italian verbs ending in -mettere follow this same rule (for example, mettere becomes messo, and permettere becomes permesso).
Could ha promesso and ha mentito mean "she promised" and "she lied"?
