Third Conditional
Definition
The Third Conditional describes hypothetical situations in the past — things that didn’t happen and their imagined results. It is used for regrets, criticism, or speculation about past events.
Formula
If + Past Perfect, would have + past participle
Key Rules
1. Use for situations that did NOT happen in the past.
2. It is completely hypothetical — the opposite of what really occurred.
3. Both clauses are unreal: the condition and the result.
4. Can use ‘could have’ or ‘might have’ instead of ‘would have’ for the result.
