門限

1. Origins, structure, and basic meaning

• Structure: 門限, read もんげん, denotes a fixed time by which a person must return home or to lodging.
• Basic usage: It names a dormitory’s ten-o’clock return deadline and the possibility of arriving after it.

  • It is a requirement to return home or to lodging by a set time, not a ban on going out altogether.
