Separable verbs are compound verbs that consist of a prefix and a base verb.
The prefix separates from the base verb in the main clause and typically moves to the end of the sentence.
Examples
Anrufen (to call): Ich rufe dich an.
I am calling you.
Aufstehen (to get up): Er steht früh auf.
He gets up early.
Wir machen das Licht aus.
We turn off the light.
