There are four different imperative forms in German. They exist for the second person singular (du), for the second person plural (ihr), for the form of formal address (Sie), and for the first person plural (wir).
In most cases, an -e may or may not be added to the verb stem to form the second person singular imperative form. For the second person plural, a -t is added to the stem. For the first person plural and third person plural imperative forms, simply use the infinitive, followed by Sie or wir. Examples sentences:
