Understanding how to use pronouns in place of nouns, and which case to put them in, will enable you to add variety to your German and will help you to communicate more effectively.
Unlike English, German has three words for ‘you’. It is important to use them correctly so that you do not offend anyone:
du is singular - use du for one friend or relative, someone you know well
ihr is plural - use ihr for several friends or relatives, people you know well
Sie is formal and can be singular or plural - use Sie for people you do not know or when you have to be respectful to them
Remember that the formal Sie (you) always has a capital letter. It sets it apart from sie with a lower case letter, which can mean either ‘she’ or ‘they’. Some people think that it has a capital letter to make it stand out from the rest, as it is a more respectful and formal form of you. To remember the capital letter, think of it as the VIP of pronouns.
Did you know?
The different words for ‘you’ are so important that German has the verbs sich dutzen, which means ‘to call each other du’ and sich siezen, which means ‘to call each other Sie’.
So in a conversation with a good friend and a teacher you could say, ‘Ich dutze dich, aber ich sieze Sie’, which means ‘I call you you (du), but call you you (Sie)’.
If you get to know someone you used to call Sie a bit better, they may invite you to call them du by saying Wir konnen uns jetzt dutzen - 'we can call each other you (du) now'.
It's illegal in Germany to use the informal form du when speaking to a policeman. You're expected to use the formal Sie. If you get it wrong, you could be fined up to 600 €.
