Questions & Answers about Dok ona podgrijava juhu, ja režem kruh.
Dok means while in this sentence. It introduces an action happening at the same time as another action.
So:
- Dok ona podgrijava juhu = While she is reheating the soup
- ja režem kruh = I am cutting bread
It connects two simultaneous actions.
Croatian normally uses the present tense for actions happening now, even where English often uses the present continuous.
So:
- podgrijava can mean reheats or is reheating
- režem can mean cut or am cutting
The context tells you that these actions are in progress. Croatian does not need a separate verb form like English am cutting.
