It is pretty unusual in English to have the same word with a completely different meaning occur twice in the same sentence. But as you will learn today, in German it is a fairly commonplace occurence.

Separable verbs often start with prefixes that are identical to prepositions. Here is a partial list of separable verbs that start with prefixes that on their own are prepositions, followed by examples of one of the verbs and the preposition:

BANNER PLACEHOLDER

Preposition: ab (from, off, starting, beginning, away)
Separable verbs: abbrennen (to burn down); abgeben (to turn in, to hand over); abkürzen (to shorten); abnehmen (to lose weight, to take something off); abschließen (to finish, to lock something)

Nimm mal die Brille ab! Er hat ganz rote Augen.

Take off the glasses! He has really red eyes.

Using the verb abnehmen and the preposition ab, you can construct a sentence such as the one below. Can you tell from the sentence structure which ab is part of the verb and which is the preposition?

From this moment on, I'm taking off my sunglasses.

Preposition: an (at, upon, on, to, towards)
Separable verbs: anerkennen (to recognize); andeuten (to hint at, to suggest); angeben (to indicate, to state, to brag); anklagen (to accuse); anschauen (to watch); anstellen (to hire, to employ); anweisen (to instruct); anwenden (to use); sich anziehen (to dress)
