A radical tour of the anatomy namespace

There are roughly thirty body-part words you'd use in daily Chinese — head, face, hand, foot, leg, eye, ear, and so on. Memorizing them one by one is a losing strategy. They are not thirty arbitrary tokens; they are thirty instances belonging to seven classes, and each class is announced by a radical.

Learn the seven radicals and the body falls out of them the same way methods fall out of an interface. Better still, the same radicals keep paying you back in verbs: anything you do with a hand has ; anything you do with a foot has 𧾷; anything that is an emotion has .

月 — the flesh module

ròu · 4 strokes
Mental model: When appears on the left or bottom of a character, it is not the moon — it is a compressed form of , meat. The two glyphs merged visually centuries ago. Think of 月-on-the-left as the Flesh interface: every character under it is a body part or soft tissue.

The food article touched 月 briefly under protein. Here it is the star. Almost every organ and limb name uses it.

Body parts with 月
肚 腿 脸 脚 肩 胸 背 肝 肺
CharPinyinMeaningHow to read it
肚子 dù zi belly, stomach 月 (flesh) + 土 (earth, phonetic). The soft part. 肚子饿 = "my belly is hungry."
tuǐ leg 月 + 退 (retreat, phonetic). The part that retreats when you walk backwards.
liǎn face 月 + 佥 (phonetic). Literally "flesh-front." Lives in 洗脸 (wash face), 丢脸 (lose face).
jiǎo foot 月 + 却 (phonetic). The foot-as-body-part. (The foot-as-action lives under 𧾷; see §4.)
jiān shoulder 月 + 户 (door). The hinge between the arm and the body.
gān liver 月 + 干 (phonetic gān). Organ names almost all follow this 月+sound pattern.
fèi lung 月 + 市 (phonetic). Same recipe: flesh + a sound hint.
Polymorphism rule (recap): 月 on the left or bottom = flesh. On the right = moon. So 明 (bright, sun + moon) keeps its moon meaning; 肺 (lung) does not. Same glyph, two types, disambiguated by position.

扌 / 手 — the hand module

shǒu · 3 strokes
Mental model: 手 alone means "hand"; its side form marks any verb done with the hands. If the character has 扌 on the left, ask yourself: what am I doing with my hand? The answer is usually the character's meaning.
Hand verbs
打 拿 推 拉 抓 握 指
CharPinyinMeaningHow to read it
hit; do (broadly) 扌 + 丁 (nail). The most overloaded hand-verb — 打电话 (make a call), 打球 (play ball), 打字 (type).
take, hold 手 underneath 合 (combine). "Bring together into the hand."
tuī push 扌 + 隹 (short-tailed bird, phonetic). The push direction.
pull 扌 + 立 (stand). The pull direction. 推拉 is a word in its own right.
zhuā grab, scratch 扌 + 爪 (claw). Literally "hand-claw."
zhǐ finger; to point 扌 + 旨 (intention). The body part and the pointing verb share one character.

Notice the noun-verb overloading in 指 (finger; to point) and 手 itself (hand; to be skilled, as in 高手 "high-hand" = expert). The hand is so central that Chinese routinely uses the body part to name the action done with it.

𧾷

𧾷 / 足 — the foot module

zú · 7 strokes
Mental model: 足 means "foot" and "enough" (a second meaning you'll see in 足够, "sufficient"). As a radical on the left of a character it is written 𧾷, and it marks verbs of locomotion.
Foot verbs and locations
跑 跳 踢 跟 路 跨
CharPinyinMeaningHow to read it
pǎo run 𧾷 + 包 (wrap, phonetic). Feet wrapped in motion.
tiào jump 𧾷 + 兆 (omen, phonetic). 跳舞 = "jump-dance" = to dance.
kick 𧾷 + 易 (phonetic yì). 踢足球 = play soccer (literally "kick foot-ball").
gēn follow; heel; with 𧾷 + 艮. Overloaded: noun (heel of the foot), verb (follow), and even a preposition ("with").
road, path 𧾷 + 各 (each). The thing every foot takes. 走路 = "walk the road" = to walk.
Feet have two homes: the body-part (jiǎo) lives under 月 (flesh); the action (run) lives under 𧾷. Same limb, two radicals — anatomy vs behavior. This is how Chinese draws the line between thing and what the thing does.

目 — the visual module

mù · 5 strokes
Mental model: Turn 目 ninety degrees and you see a pictograph of an eye on its side, pupil in the middle. Anything about vision, attention, or sleep (because sleep is what closed eyes do) lives here.
Eye characters
看 眼 睡 眉 盯
CharPinyinMeaningHow to read it
kàn look; read; watch 手 (hand) + 目 (eye). A hand over the eyes — shading them to see far. Covers watching TV, reading a book, looking at anything.
yǎn eye 目 + 艮 (phonetic). The noun for eye. 眼睛 (yǎnjing) is the two-character form you'll hear most.
shuì sleep 目 + 垂 (droop). Drooping eyes = sleep. 睡觉 (sleep) literally "sleep-sense."
méi eyebrow The top part is a stylized brow; 目 below is the eye it sits above.

耳 — the audio module

ěr · 6 strokes
Mental model: 耳 is an ear on its side. It shows up in characters about hearing, attention, and — surprisingly — jobs: historically, holding office meant having someone's ear.
Ear characters
耳 取 聪 职 聊
Surprise: (tīng, "listen") does not contain 耳 in simplified Chinese — it uses 口 (mouth) plus 斤 (axe). The traditional form 聽 did contain 耳. This is one of those characters where the simplification lost the semantic radical in favor of a shorter glyph. Keep 听 in your mental model of the audio namespace even though its radical no longer agrees.
CharPinyinMeaningHow to read it
耳朵 ěr duo ear (the body part) The everyday word for ear. 朵 is a measure word for flowers; here it's a flowery suffix that stuck.
聪明 cōng míng clever, smart 聰 has 耳 on the left — "quick of ear." Paired with 明 (bright), you get "sharp-eared and clear-eyed" = clever.
liáo chat 耳 + 卯 (phonetic). You chat with ears, not just mouths. 聊天 = "chat-sky" = casual conversation.
zhí duty, job 耳 + 只 (only). Having an official's ear = having a post. 职业 (profession), 辞职 (resign).

口 — mouth, lip, tongue

kǒu · 3 strokes
Mental model: The food article covered 口 as an I/O interface (eating and speaking). Here we zoom in on the hardware — the parts of the mouth itself.
Mouth anatomy
嘴 唇 舌 喉
CharPinyinMeaningHow to read it
zuǐ mouth (casual) 口 on the left + a stack of components. In modern speech this is the go-to word for mouth; 口 alone is more formal or compositional.
chún lip 口 at the bottom + 辰 (phonetic). 嘴唇 = "mouth-lip" = lips.
shé tongue The bottom component is 口. 舌头 (tongue) is the everyday form.
hóu throat 口 + 侯 (phonetic). 喉咙 = throat (as a passage, not just the part outside).

心 / 忄 — heart and mind

xīn · 4 strokes
Mental model: Chinese locates thought and emotion in the heart, not the brain. 心 (heart) as a radical appears in two forms: 心 at the bottom of a character (想, 思, 念), and on the left (怕, 忙, 情). Any character with either form is about something the mind does.
Mental states
想 怕 忙 愿 情 怒 快
CharPinyinMeaningHow to read it
xiǎng think; want; miss 相 (phonetic) + 心. The workhorse mental verb — thinking, wanting, and missing someone all use 想.
fear 忄 + 白 (phonetic bái). Emotion + a sound hint. "My heart goes pale."
máng busy 忄 + 亡 (lose/perish). When your heart is "lost" in activity, you are 忙.
yuàn wish, be willing 原 (origin) + 心. A wish is a heart's origin-state. 愿意 = to be willing.
qíng feeling, emotion, situation 忄 + 青 (phonetic qīng). Shows up in 爱情 (romantic love), 感情 (feelings), 心情 (mood).
anger 奴 (slave, phonetic) + 心. Specifically the hot, boiling kind of anger, as in 愤怒.
kuài fast; happy 忄 + 夬. Overloaded: 快 as "fast" (快跑 = run fast) and 快 as "happy" (快乐 = happy). Same radical-side heart is doing both.

9. Putting it together

Once you have the seven radicals, whole-body vocabulary starts compounding from the parts. A handful of compounds worth knowing:

WordPinyinMeaningDecomposition
身体 shēn tǐ body, health 身 (torso) + 体 (form). The global word for "the body" when asking about someone's health.
tóu head Standalone — no flesh radical (the simplified 头 lost it). Use it in 头发 (hair), 头疼 (headache).
鼻子 bí zi nose 鼻 is its own radical. 子 is the noun-suffix seen all over body-part words (肚子, 脖子, 眼睛 doesn't use it but 嗓子 does).
脖子 bó zi neck 月 (flesh) + 孛 (phonetic) + 子 (noun suffix). Standard flesh-radical anatomy.
胳膊 gē bo arm Both characters take 月. The whole word is "flesh-flesh" — two components of the same module, reinforced.
手指 shǒu zhǐ finger 手 (hand) + 指 (point). Both characters you already know; the compound is self-describing.

10. Sentence patterns

Five sentences that fall out of this vocabulary once you have the radicals.

// 我 头 疼。
// wǒ tóu téng
// "My head hurts." (topic-comment, no verb "to have")
me.head.aches === true;

// 她 的 眼睛 很 大。
// tā de yǎnjing hěn dà
// "Her eyes are big." (的 = possessive, 很 = degree filler)
her.eyes.size === "big";

// 我 想 睡觉。
// wǒ xiǎng shuìjiào
// "I want to sleep." (想 = want, also "think")
me.want(sleep);

// 他 跑 得 很 快。
// tā pǎo de hěn kuài
// "He runs fast." (得 introduces a manner/degree complement — see §11)
him.run().speed === "fast";

// 你 的 身体 好 吗?
// nǐ de shēntǐ hǎo ma?
// "How's your health?" — the canonical wellness check-in
your.body.status === "good"?;
