Questions & Answers about Dok god nema magle, možemo da siđemo.
Dok god means as long as.
It introduces a condition that remains true for some period of time:
- Dok god nema magle, možemo da siđemo. = As long as there is no fog, we can go down.
A close alternative is sve dok. In many contexts, dok god and sve dok are very similar.
In Serbian, existence and absence are often expressed with ima/nema:
- ima magle = there is fog
- nema magle = there is no fog
So nema magle is the natural way to say there is no fog.
Nije magla would mean it is not fog, which is a different idea. That would only make sense if you were identifying something and denying that it is fog.
