Questions & Answers about Har De en saks, så jeg kan klippe billedet ud?
Because this is a yes/no question.
In Danish, yes/no questions usually have the finite verb first and the subject second:
- Statement: De har en saks.
- Question: Har De en saks?
So Har De ...? is the normal question pattern, just like English Do you have ...?
De means you in a formal/polite way.
So the speaker is addressing someone respectfully, not casually. In everyday modern Danish, people usually say du instead, but De is still correct in formal situations.
The capital letter shows that it is the formal pronoun De.
This helps distinguish it from de, which usually means they or those.
So:
- De = formal you
- de = they / those
