How it's used

Focuses specifically on the physical obstruction of pipes, drains, or waterways by sediment or debris. While it can describe a medical condition like a blocked blood vessel, it is most frequently heard in the context of household maintenance or urban infrastructure problems. It carries a slightly more formal or technical tone than the common word 塞.

Examples

This drain is clogged, causing water to be all over the floor.

Common mistake

Do not confuse this with the general verb 塞, which can be used for traffic jams or a stuffed nose. 淤塞 implies a buildup of material like sludge or silt rather than just a temporary congestion of people or objects.
