"If" Clause - The third conditional

1. A third conditional is a conditional sentence used to talk about the past. It refers to something that did not happen in the past and can therefore express regret.

2. The third conditional is formed by the if clause and the main clause. The if clause is composed of verbs in the past perfect, while the main clause involves several verbs and the most used are: would have, could have and might have. After the main clause, the verbs that appear are in the past participle. if + past perfect + would have, could have, might have + past participle

3. Example: If he had come on Monday, I would have seen him. (Se ele tivesse vindo na segunda, o teria visto) If she had worked more, she could have saved more money. (Se ela tivesse trabalhando mais, poderia ter economizado mais dinheiro) If we had studied harder, we might have passed the test. (Se nós tivéssemos estudado mais duro, poderíamos ter passado na prova)
