Third Conditional IF (Unreal Past)
Third conditional if
, also known as type three conditional
, is used for unreal situations in the past.
One can also think of it as the imaginary case. The condition statement was unreal in the past, the condition was not met and the dependent did not happen.
If the weather had been nice yesterday, I would have barbecued.
If I had been rich, she would have come with me last July.
If the weather had been nice...
The weather was not nice, we couldn't/didn't barbecue. (Unreal/imaginary situation in past)

As in the first and second conditional, the if clause and the main clause can be swapped.
