違反

1. Origins, structure, and basic meaning

• Structure: 違反 is read as いはん and functions as a noun or with する for breaching an established law, rule, or agreement.
• Basic usage: Mark the breached standard with に in 規則に違反する, or form a type such as 駐車違反.

2. Common pitfalls and similar expressions

• Standard marked by に
  • The regular pattern is 規則に違反する, with に identifying the rule that was violated.
• Mistake versus violation
  • It is not merely an error; an applicable rule or restriction has been breached, and a parking notice records that judgment.
