The Subjunctive II Forms of German Modal Verbs

German modal verbs—müssen, sollen, können, wollen, dürfen and mögen—are among the most frequently used verbs in German. In the conditional or subjunctive form, known as Konjunktiv II, they generally use their own forms rather than the würde + Infinitiv construction.

For example, you do not say ich würde können. The correct form is ich könnte.

Common mistakes

  1. Using würde + Infinitiv with modal verbs

    Correct: Ich könnte helfen.
  2. Putting the infinitive in the wrong position
    Incorrect: Ich müsste gehen nach Hause.
    Correct: Ich müsste nach Hause gehen.
  3. Confusing möchte and wollen
    Ich will einen Kaffee. means “I want a coffee” and sounds stronger and more definite.
    Ich möchte einen Kaffee. means “I would like a coffee” and is more polite.

Summary

In Konjunktiv II, German modal verbs use their own forms: müsste, sollte, könnte, wollte, dürfte and möchte.

Practical steps

  1. Memorise the six key forms: müsste, sollte, könnte, wollte, dürfte, möchte.
  2. Practise each verb with all six persons: ich, du, er/sie/es, wir, ihr, sie/Sie.
  3. Write two everyday sentences for each verb.
  4. Check that a full infinitive, such as gehen or helfen, appears at the end of the sentence when required.
  5. Use möchte for polite requests and distinguish it from the stronger will.
