傍受

1. Origins, structure, and basic meaning

• Structure: 傍受 is read as ぼうじゅ and functions as a noun or with する for intercepting communications or radio signals in transit.
• Basic usage: Use 通信を無断で傍受する for unauthorized interception and 電波を傍受した記録 for a record of received signals.

2. Common pitfalls and similar expressions

• Type of object
  • It naturally applies to technical interception of communications or radio waves, not merely overhearing an ordinary nearby conversation.
• Unauthorized condition
  • 無断で makes the interception prohibited in that sentence; the modifier should not be treated as part of every possible use of 傍受.
