Meaning
The kanji 庸 means ordinary, mediocre, and commonplace. It describes something pitched at the average — neither exceptional nor terrible, simply unremarkable. But 庸 is not one-dimensional. In philosophical contexts it signals virtue, pointing toward the Confucian ideal of balance. In everyday use it lands harder, serving as quiet but pointed criticism of someone who lacks talent, distinction, or drive.
The character is built from the radical 广 (madare) — a shape representing the slanted roof of a shelter — combined with an inner component relating to use and function. Together they once pictured a worker employed beneath that roof for common, unskilled tasks. The meaning drifted from the act of hiring, to the hired worker, to the abstract quality of being average. Each step in that chain survives in modern compounds.
庸 has 11 strokes and carries the radical 广. As a secondary Jōyō kanji at high school level (Grade 8 equivalent), it rarely appears in casual speech. When you do encounter it in writing, the surrounding text is almost certainly literary, philosophical, or academic — spotting 庸 is a sure sign the register has shifted.
庸's most important philosophical role is in 中庸 (chūyō), the Confucian Doctrine of the Mean — one of the Four Books of Confucianism. The doctrine holds that virtue lies not in extremes but in balance: neither excess nor deficiency. Here 庸 sheds its negative edge entirely, coming to represent the wisdom of measured, centered living. Anyone reading classical Japanese or Chinese texts in depth will meet this concept repeatedly.
Readings
On'yomi (音読み) — Chinese-derived readings
The only on'yomi for 庸 is ヨウ (yō), traced to its Middle Chinese pronunciation. It appears almost exclusively in compound words (熟語, jukugo). Reading 庸 in isolation is extremely uncommon — the character needs other kanji around it to reveal its meaning.
Key compounds using the on'yomi ヨウ:
- 中庸 (chūyō) — the golden mean; the Confucian Doctrine of the Mean; balance as a guiding principle
- 凡庸 (bonyō) — mediocrity; the quality of being ordinary and unremarkable
- 平庸 (heiyō) — humdrum, prosaic, lacking distinction or originality
- 庸才 (yōsai) — mediocre talent; a person of no special ability
- 登庸 (tōyō) — formal appointment to an official position (classical usage)
Kun'yomi (訓読み) — Native Japanese readings
庸 has no productive kun'yomi. Some historical references list つね (tsune, "ordinary") as an archaic kun reading, but it does not appear in contemporary Japanese. もちいる (mochiiru, "to use") surfaces occasionally in classical texts — a remnant of the kanji's ancient employment meaning — but is equally archaic and not examined on the JLPT. For the N1, ヨウ is all you need. Everything meaningful about this character lives in its compounds.

Memory Tip
Picture a large roof (广) sheltering an entirely ordinary worker hired for the most common of tasks. Standard tools (用), nothing exceptional — just everyday labor, done quietly and forgotten. That image holds both sides of the character: the act of hiring for common work, and the quality of being utterly unremarkable. The sound cue reinforces it: ヨウ (yō) matches 用 (yō, "use"), a direct echo of the hire-for-use origin. See 庸 — think: roof, ordinary worker, hired, invisible.
