Conditionals: Second, Third & Mixed

These conditionals deal with unreal or imaginary situations.

TypeUseStructureExample
Secondunreal present/futureIf + past, would + verbIf I had money, I would travel.
Thirdunreal past (regret)If + past perfect, would have + p.p.If I had studied, I would have passed.
Mixedpast condition → present resultIf + past perfect, would + verbIf I had saved, I would be rich now.

Second: If I were you, I would apologise.

Third: If she had left earlier, she wouldn't have missed the bus.

Second = imaginary now (use past + would). Third = imaginary past (use past perfect + would have). With "I/he/she," formal English uses "were": If I were rich…

Common mistake: "If I would have…" in the if-clause. Use had + past participle: "If I had known…"
