Third Conditional

English Grammar


When we are talking about something in the past which cannot be altered now, we use:

If + Past Perfect, would have + past participle

EXAMPLE: If you had studied all of these grammar pages, you would have passed the exam.

You can not alter or change the past. You didn't study in the past (something you cannot change now) so you didn't pass the exam. It is an imaginary situation that didn't happen.

Notice how this tense can be used to say that you regret doing something or when you are telling someone off (reproaching someone). This type of conditional can also be used when making excuses.

We can also change the word order of the sentence...

Would have + If + past perfect

EXAMPLE: You would have passed the exam if you had studied all of these grammar pages.
