  • Antonym遵守じゅんしゅNeutralAntonym. Observing laws and rules, as in 「法令を遵守する」 — the opposite of 「違反」.

Default to 「違反」 for breaking rules or regulations. Use 「違犯」 when the act constitutes a crime, 「反則」 for fouls in matches, 「破る」 for broken promises, and 「侵害」 for harm to rights; the antonym is 「遵守」. For defying people or authority, choose 「背く」「逆らう」「反抗」, or colloquially 「楯突く」「歯向かう」; 「犯す」 is the verb for committing a bad act. 「違背」「干犯」「抗する」「背反行為」 are rare written words.
