One of the most important questions about German is when to use "Sie" (the formal "you") and when to use du/ihr (the informal "you").
Let's try and clear this up!
Often, to show respect for someone that you used du with, "Du", "Dich" and "Dir" are capitalized even though official German grammar rules say that it should not be capitalized.
Kannst Du kommen?
Can you come?
When you wish to use "du" with someone, you ask:
Wollen wir uns duzen?
Should we use "du"?
Usually, the older person asks the younger person.
To conclude this section, we'll listen to the melodic song "Und wenn ein Lied" by Xavier Naidoo
