Synonyms & antonyms
  • Antonym変則へんそくWrittenA written, formal antonym of 「正規」: contrasts with it in whether something is standard, referring to what departs from the established rules.
  • Antonym非正規ひせいきNeutralNeutral antonym of 「正規」 on the regular–non-regular axis, best known from non-regular employment such as 「非正規雇用」, as opposed to regular full-time staff.

Use 「正規」 for what is official and based on established rules, as in 「正規雇用」 and 「正規品」. For the opposite, 「非正規」 marks what falls outside the regular category, notably non-regular employment, while 「変則」 is for what breaks the usual pattern.
