Don't worry, it's free.
We have already talked about the nominative, akkusative&dative, and in this chapter we will finally deal with the last case, the genitive! Although you can now get around this case very well within the German language, it is not unimportant and is often used in certain situations. But what do we actually use the genitive for? As mentioned briefly in the last chapter, we use the genitive to indicate possession. But more about that now in this chapter!
