This lesson's sole purpose is to give you a first and simple insight into the logic of the adjective endings.
The German adjective endings seem horribly confusing. But don't despair. That is only if you haven't been taught the logic behind them properly yet. This lecture will take care of this. The aim is NOT that you learn any endings here by heart. Please don't! You'll be exposed to every case's specific set of endings as you proceed with this course. The preaching exercises play an important role in this.
Also try to explain in your own words what you have learned in this lesson.
