A1 - Separable verbs
EINkaufen [to buy] and VERkaufen [to sell]: one verb is separable, the other isn’t. So you would say, “Ich kaufe Tomaten ein,” [“I’m buying tomatoes”], but “Ich verkaufe Tomaten” [“I’m selling tomatoes”].
Our teacher will explain why this happens, and show you that it’s not all that difficult.
As always, directly from a classroom in our language school in the heart of Vienna!
