How it's used
Focuses on the sudden release of pressure or tension that causes an object to split or burst. It is frequently used for food items like buns or popcorn, but also for physical objects like bags or seams that fail under stress. The addition of 咗 emphasizes the completed state of the bursting action.
Examples
The bag was packed too full and it popped open.
Related words
Common mistake
Avoid using this for abstract concepts like emotions or secrets, as it is strictly for physical objects bursting or splitting. For emotional outbursts, use 爆發 instead.
