申告

1. Origins, structure, and basic meaning

• Structure: 申告 is read as しんこく and functions as a noun or with する for formally declaring or reporting facts or items to an office or responsible party.
• Basic usage: Use 荷物の中身を申告する for the declared content and the compound 申告書 for the declaration form.

2. Common pitfalls and similar expressions

• Formal declaration
  • It is more procedural than simply informing someone with 知らせる, as shown by declaring luggage contents or completing a declaration form.
• Use inside a compound
  • 申告書 contains the headword but names the form used to make the declaration rather than the act itself.
