Conditional Sentences
We talk about the past with the 3rd conditional. It is like a dream, with no possibility that the dream can come true. We are thinking about an impossible condition in the past.
| CONDITION | RESULT | |
| had + past participle | would have + past participle | |
| If | I had been born in Spain | I would have learnt Spanish easily |
I wasn’t born in Spain, so this whole situation is impossible: it can never come true. Both the result and the condition are impossible now. Instead of would have, sometimes we can also use should have, might have and could have.
