The Third Conditional

The Third Conditional

1. What is

   • We make the third conditional by using the past perfect after 'if' and then 'would have' and the past participle in the second part of the sentence:
   • Is used
     • It talks about the past. It's used to describe a situation that didn't happen, and to imagine the result of this situation.

2. Structure

   • if + past perfect, ...would + have + past participle

3. Example
