掲示板

1. Origins, structure, and basic meaning

• Structure: 掲示板, read けいじばん, means a board or space where notices and messages are posted for others to read.
• Basic usage: In 駅の掲示板に地域の催しの案内が貼られていた。, a notice about a local event is posted on the station bulletin board.

2. Common pitfalls and similar expressions

• Physical and electronic boards
  • Notices are attached to the station's 掲示板, while questions are posted to the class's 電子掲示板. The medium changes, but both provide a shared place for information to be read.
