Every time you talk to someone in German, you'll need to know which word for you to use, du or Sie .

You use du for people with whom you're on first-name terms, such as family, close friends and children. du is also used in informal situations, in particular among young people.

Sie is more formal and is used with people who you would address with their surname.

When you address someone as du or Sie, the verb changes as well.

Sind Sie Herr Schmidt? Are you Mr Smith?
Bist du Peter? Are you Peter?

Is it Sind Sie or is it Bist du? Please try and complete the sentence correctly. You'll need to fill the right words into the gap.
