How it's used

While 門 literally refers to a physical door or gate, it frequently functions as a classifier for academic disciplines or schools of thought. It carries a sense of entry or access, which is why it appears in compound words related to openings like valves or ports. In casual speech, it is the standard word for both the physical object and the metaphorical gateway to a subject.

Examples

Remember to close the door, it is very windy.

Common phrases

to open the door
to close the door

Common mistake

Learners often confuse 門 with 門口. While 門 refers to the door itself, 門口 specifically designates the doorway or the entrance area of a building.
