Third & mixed conditionals
The third conditional imagines a different past: If I had studied, I would have passed.
1What is it?
The third conditional imagines a different past: If I had studied, I would have passed. A mixed conditional links a past condition to a present result: If I had studied, I would be a doctor now.
2Why do we use it?
Regret, reflection and “what if” conversations — interviews, storytelling and honest self-talk all use them.
3The simple rule
Third: if + past perfect, would have + participle. Mixed: if + past perfect, would + base verb (present result).
4Formula
3rd: if + had + participle, would have + participle · Mixed: if + had…, would + verb now
