The conditional mood, often expressed using Konjunktiv II in German, is used to describe hypothetical situations, polite requests, or actions that would happen under certain conditions.
It is similar to the English "would" + verb construction.
Formation
The conditional tense is usually formed with the auxiliary verb würden + the infinitive of the main verb.
Alternatively, certain verbs use their specific Konjunktiv II forms.
Examples
Ich würde zur Schule gehen.
