Answer 2

Start with a greeting.
The simplest greeting is Hallo or Guten Tag, which means Hello or Good Day. If you’re in Southern Germany, they say Grüß Gott instead.
Introduce yourself.
The two most common ways to introduce yourself are to say Ich heiße Name (My name is Name) or Ich bin Name (I’m Name).
