Third Conditional Examples (100 Sentences)

The third conditional is used to talk about hypothetical situations in the past—things that did not happen—and their imagined results. It often expresses regrets, missed opportunities, or imagined alternatives to past events.

Structure of the Third Conditional

• If + past perfect, + would have + past participle

This structure can also use modal verbs like could or might instead of would.

Example:
