Meaning
倫 means ethics, morals, and the ordered relationships between people. The kanji covers both abstract moral principles and the concrete hierarchy of social bonds — parent and child, ruler and subject, teacher and student.
Two components build this character. The left side is 人偏（にんべん）, written as 亻. The right side is the phonetic-semantic component 侖, which originally depicted bundled documents arranged in careful sequence — like scrolls kept in a scholar's orderly archive. Together they suggest people arranged in proper order, which is the foundation of ethical conduct.
At 10 strokes, 倫 is a Jōyō kanji taught at the high school level. Don't expect to hear it in casual conversation. It belongs in academic papers, newspaper editorials, and legal codes — wherever Japanese is used to discuss how people ought to behave.
The kanji spans several related ideas: ethics as an abstract principle, the natural hierarchy of human relationships, one's peers or equals in rank, and principled orderliness of thought or conduct. That range explains the variety of important compound words built around it.
Readings
On'yomi (音読み) — Chinese-derived readings
The on'yomi is リン (RIN). It entered Japanese through Confucian and Taoist texts, where the ethics of human relationships occupied center stage. That classical origin is why リン sounds formal — and why it appears almost exclusively in compound words rather than standalone speech.
Key compounds using リン:
- 倫理 (rinri) — ethics, morality; the most common compound, found across news, academia, and workplace codes of conduct
- 不倫 (furin) — adultery, an extramarital affair; ubiquitous in modern media
- 絶倫 (zetsurin) — peerless, without equal; used for exceptional talent or ability
- 人倫 (jinrin) — the moral order governing human relationships
- 天倫 (tenrin) — natural bonds of kinship, especially between parent and child
Kun'yomi (訓読み) — Native Japanese readings
倫 has no standard kun'yomi in modern Japanese. In classical texts the reading のり occasionally appears with the sense of "rule" or "guiding principle," but it's rare enough to skip. Knowing 倫理 and 不倫 covers the vast majority of real encounters with this kanji.

Memory Tip
Picture a person (亻) carefully arranging scrolls and books (侖) on a shelf. The component 侖 originally depicted documents organized in systematic order — a scholar's library kept perfectly neat. The person beside this arrangement represents orderly human conduct: someone whose moral life is as principled as a well-kept row of books.
The core compound: 倫 (ordered person) + 理 (principle) = 倫理, ethics. And 不倫 is literally not-orderly — the breaking of moral order, which is exactly what an affair represents socially.
