ethics

1. Origins, structure, and basic meaning

• Structure: 倫 concerns principles governing human relationships; its on-reading is りん.
• Basic usage: 倫理(りんり) denotes moral principles used to judge conduct.

2. Common pitfalls and similar expressions

• Broad ethics and a particular relationship
  • 研究倫理 means research ethics. In everyday modern usage, 不倫(ふりん) mainly refers to an affair outside marriage, rather than every kind of unethical conduct.
• Ethical issues
  • In 倫理上の問題, 上 marks the ethical aspect or perspective, not a physical position above something.
