How it's used
Primarily used in medical or technical contexts to describe physical blockages like arteries or pipes. While it can describe traffic congestion, it carries a more formal or clinical tone compared to everyday words like 塞住. It implies a complete or significant lack of flow rather than just a minor delay.
Examples
Do you know why the road is so congested?

Common mistake
Avoid using this to describe social awkwardness or a person being closed-minded, as it specifically refers to physical or structural obstruction. For describing a person's personality, use 固執 instead.
