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.

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.
