In "Learn German with Anja," Anja teaches basic German greetings and goodbyes, explaining their appropriate usage throughout the day. She outlines *Guten Morgen* for mornings, *Guten Tag* for daytime (from about 10 a.m.), and *Guten Abend* for evenings. Before bed, one says *Gute Nacht*, noting that "Nacht" is feminine, thus using "Gute" instead of "Guten," and *Schlaf schön* (sleep well) can follow. For informal greetings among friends and family, *Hallo*, *Hi*, or the versatile *Na* are common. Regarding goodbyes, *Auf Wiedersehen* is the formal option, literally meaning "to see you again." More casually, one can say *Tschüss*, *Tschüssi*, or *Ciao*. Anja also introduces *Bis später*, meaning "see you later," before concluding with an interactive homework assignment for viewers.
