How to say "discredit" in Japanese

• 不信ふしんCommon
  nounCovers 'discredit' as the state of being distrusted or disbelieved — loss of another's trust or confidence. The common word for this sense, as when officials or institutions lose the public's confidence.

  Hanako questioned his sincerity.
• 名折れなおれ
  nounCovers 'discredit' in the sense of disgrace or dishonor — conduct or events that tarnish a person's or group's name and reputation. A less common word than 不信, and not about loss of trust.
• 不信用ふしんよう
  nounCovers 'discredit' as distrust, like 不信, but it is a less common word; for this sense 不信 is usually the word you actually want.

For 'discredit' as loss of trust or belief in someone or something, use 不信, the common word; for disgrace that damages a person's name or reputation, use 「名折れ」; 不信用 expresses the same distrust sense but is less common.
