Meaning
The kanji 僧 (ソウ) means Buddhist monk or priest — someone who has taken monastic vows and joined the ordained community. Buddhism arrived in Japan from the Korean Peninsula in the 6th century CE. In the 1,400 years since, it has shaped the country's art, architecture, philosophy, and daily ritual life, and 僧 names the person at the center of that world.
The character has an unusual origin: it is one of the few cases where a Sanskrit word was compressed into a single Chinese character. The word traces back to the Sanskrit saṃgha (サンガ), the Buddhist community of ordained practitioners — one of the Three Jewels of Buddhism alongside the Buddha (仏) and the Dharma (法). The full transliteration into Chinese was 僧伽 (そうぎゃ), eventually abbreviated to just 僧. Rather than a semantic compound, this kanji is phonetic shorthand for a borrowed concept — a word shaped by the Silk Road transmission of Buddhism into East Asia.
Structurally, 僧 pairs the 亻 (person radical, a simplified form of 人) on the left with 曽 (ソウ) on the right. The person radical marks this as a human category; 曽 provides the ソウ reading. The combination points toward a person of the saṃgha.
At 13 strokes, 僧 is a grade 8 Jōyō kanji — on Japan's official list of standard characters, but typically learned after elementary school. You'll encounter it in classical literature, temple inscriptions, and journalism covering Buddhism or Japanese cultural history.
Readings
On'yomi (音読み) — Chinese-derived readings
僧 has one on'yomi: ソウ (sō), which traces back through Chinese to the Sanskrit saṃgha. Since the concept and the word arrived in Japan together, ソウ appears in virtually every compound containing this kanji.
ソウ stays in formal, religious, literary, and historical contexts. It rarely voices to ゾウ in compounds — the main exception being 若僧. Key compounds:
- 僧侶 (sōryo) — Buddhist monk, Buddhist priest; the standard modern formal term for an ordained member of the Buddhist clergy
- 僧院 (sōin) — monastery, abbey; a residential religious institution where monks or nuns live and train
- 高僧 (kōsō) — eminent monk, high priest; a senior or historically distinguished Buddhist clergyman
- 禅僧 (zensō) — Zen monk; a practitioner ordained in the Zen school of Buddhism
- 尼僧 (nisō) — Buddhist nun; a female ordained member of the Buddhist monastic order
Kun'yomi (訓読み) — Native Japanese readings
僧 has no standard kun'yomi. The reason is straightforward: the concept of a Buddhist monk arrived in Japan from continental Asia, so there was no native Japanese word already waiting for this kanji.
In spoken Japanese, monks are often called 坊主 (bōzu) colloquially, but that's a separate word with different kanji — not a kun'yomi of 僧. The one exception worth knowing is 若僧 (wakazō) — young monk, or colloquially, a brash and inexperienced youth. Here 僧 voices to ぞう via rendaku, but only in this fixed compound.

Memory Tip
Split 僧 into two parts. On the left: 亻, the person radical. On the right: 曽, found in words about deep time — 曽祖父 (great-grandfather). Picture a person who has turned their back on the present to live inside ancient texts, rituals, and wisdom. A monk does exactly that.
The reading ソウ is also an echo of Sanskrit: it traces back through Chinese to saṃgha. Every time you hear ソウ in a religious context, you're following a sound that traveled from ancient India through China to Japan.
