The Third Conditional

Average: 3.5 (63 votes)

The third conditional is quite complex. Read the information below to help you understand it, then see if you can convert the following sentences into the third conditional. Good luck!

The third conditional is used:

To talk about 'impossible' conditions. They are impossible because they happened in the past and we cannot change them.

It is formed in the following way:

If + past perfect, would have + past participle

"If I had known you were going to the cinema, I would have gone too."

Or the structure can be reversed:

Would have + past participle + if + past perfect

"I would have gone too If I had known you were going to the cinema."

Also note: would can be replaced by could or might.
