The conditional type three 3

The conditional type three 3

Definitions:

* We use the third conditional to talk about imaginary situations in the past. They are often the opposite of what really happened: if I had had enough money, I would have bought this car.  (I did not have enough money, so I did not buy this car).

*The type 3 conditional refers to an impossible condition in the past and its probable result in the past. These sentences are truly hypothetical and unreal because it is now too late for the condition or its result to exist. There is always some implication of regret with type 3 conditional sentences. The reality is the opposite of, or contrary to, what the sentence expresses. In type 3 conditional sentences, the time is the past and the situation is hypothetical.

Examples:

If had owned a car, I would have driven to work. But I didn't own one, so I took the bus.

She would have traveled around the world if she had had more money. But she didn't have much money, so she never traveled.

Form

We make the third conditional with:

If+subject+Past perfect, subject+would/wouldn't+have+past participle.

Negative form

If we had not crashed our car; we wouldn't have been late.

Question Form

We make questions in the third conditional with:

(Question word)+ would+subject+have+past participle...+if+subject+past perfect

A: What would you have done if you had won the lottery last week?
B: I would have bought a house.

*In type 3 conditional sentences, you can also use modals in the main clause instead of "would" to express the degree of certainty, permission, or a recommendation about the outcome.

we can also use could and might in the main clause to mean 'would perhaps': 

If the men hadn't run away, she could have killed them.
If it had been me; I might have left a note on the car.

*The if clause can be first or second in the sentence.
