Modal verbs in past unreal

Konjunktiv II of modal + Infinitiv II: Ich hätte das machen können. (I could have done that.) / Er hätte früher kommen müssen. (He would have had to come earlier.)

⚠️ "würde + Partizip II" does NOT exist in German. The only way to express past unreal is hätte/wäre + Partizip II. This is one of the most common errors made by advanced learners.

⚠️ COMMON MISTAKES

❌ "Ich hätte das gemacht müssen." (Partizip II instead of infinitive)

✓ "Ich hätte das machen müssen."

The Ersatzinfinitiv rule applies here too: two infinitives at the end, modal last. Never use Partizip II with hätte + modal.

❌ "Ich hätte das machen gemusst."

✓ "Ich hätte das machen müssen."

The modal stays in the infinitive — müssen, können, sollen, dürfen, wollen. Never gemusst, gekonnt etc. in this structure.

🧠 REMEMBER:
hätte + two infinitives at the end — modal always last.
Same rule as Perfekt with Ersatzinfinitiv, just haben becomes hätte.

Perfekt: habe machen müssen
Konj. II past: hätte machen müssen
