Conditional perfect

What is it ?
- It’s a tense used to say what would have happened.
- It is formed with the auxiliary verb (être or avoir) in the conditional tense and the past participle.
- When you use être as the auxiliary, the past participle must agree in gender and number with the subject.
- That means adding an extra E for the feminine, S for the plural and ES for the feminine plural.
