Type 3 and mixed conditionals express hypothetical situations in the past or across time. 🔹 TYPE 3 — Impossible past condition : • Used for hypothetical situations that did NOT happen in the past. • Structure: If + past perfect, would have + past participle • Examples: - If I had studied harder, I would have passed the exam. (But I didn't study → I didn't pass) - If she had come earlier, she would have met him. - If we had saved money, we would have bought a house. 🔹 MIXED CONDITIONALS : Combine type 2 and type 3 — past condition with present result, or present condition with past result. • Past condition → present result : If + past perfect → would + base verb - If I had studied medicine, I would be a doctor now. (I didn't study medicine → I am not a doctor now) • Present condition → past result : If + past simple → would have + past participle - If I were braver, I would have spoken to her. (I am not brave → I didn't speak to her) 🔹 Summary of all types : | Type | If clause | Main clause | Meaning | | 1 | present simple | will + inf | real/possible | | 2 | past simple | would + inf | imaginary present | | 3 | past perfect | would have + pp | impossible past | | Mixed | past perfect | would + inf | past→present | ⚠️ Common mistakes : • ❌ If I would have known → ✅ If I had known • ❌ I would have went → ✅ I would have gone
