Questions & Answers about Først når vi har læst bogen, drøfter vi temaet.
Først når means only when or not until.
So the idea is:
- first, we read the book
- only after that, we discuss the theme
A very close English version is:
Only when we have read the book do we discuss the theme.
It adds a stronger sense of sequence than just når by itself.
This is because Danish is a verb-second language in main clauses.
The first element in the sentence is the whole subordinate clause:
Først når vi har læst bogen
After that, the finite verb of the main clause must come next, so you get:
drøfter vi temaet
Pattern:
- first position: Først når vi har læst bogen
- second position: drøfter
- then subject: vi
This is very common in Danish. Compare:
- Vi drøfter temaet.
- I morgen drøfter vi temaet.
- Når vi er klar, drøfter vi temaet.
