Bùshǒu — Radicals: How Characters Are Built
The most important unit in the elementary years. Until now characters have been things to memorise one at a time. This unit reveals that they’re built from parts — and that the parts tell you what the character means.
The whole idea, in one row
Every character below contains the water radical 氵. Notice what they have in common before reading the translations:
河 river · 海 sea · 游 swim · 洗 wash · 渴 thirsty
A student who sees 氵 in an unfamiliar character now knows something about it before knowing anything else. That is the shift this unit exists to produce.
The eight radicals
Chosen because each one unlocks characters students already half-know.
木
口
亻
扌
论
女
艹
Unit objectives
- Recognise eight common radicals and say what each means
- Find the radical inside a character they already know
- Guess the general meaning of an unfamiliar character from its radical
- Sort a pile of characters into radical families
- Spot the sound component as well as the meaning radical
- Predict how an unfamiliar character might be pronounced
Radicals at work
口 mouth → 吃 eat · 叫 call · 喝 drink
论 speech → 说 say · 请 please · 谢 thank
女 woman → 妈 mum · 姐 sister · 好 good
木 tree → 林 woods · 森 forest · 桌 desk
形声 — the part that tells you the sound
Radicals tell you what a character is about. But most characters carry a second component that tells you roughly how it sounds — and that pattern covers roughly 85% of all Chinese characters. It is the single most useful thing a reader can know.
女 woman · meaning + 马 mǎ · sound only = 妈 mā · mother
There is no horse in the idea of a mother. 马 is present purely because it sounds right.
One sound component, five characters
Every character below contains 青 qīng. Read the sounds aloud — the pattern is unmistakable:
清 qīng water → clear · 请 qǐng speech → please · 情 qíng heart → feeling · 晴 qíng sun → sunny
A student who learns 青 has a running start on four more characters. That is the compounding effect that makes 900 characters reachable — and why character learning speeds up rather than slowing down.
Be honest about the limits. The sound clue has drifted over two thousand years, so treat it as a hint that narrows the options rather than a rule. 睛 jīng contains the same 青 and has wandered further than the others. Guess, check, move on.
Full explanation, with examples →Five lessons that change how characters feel
The water family
One radical, six characters. Students discover the pattern themselves before it’s named, which is the point.
Mouth, speech, heart
Three radicals about communicating and feeling — and why 快 (fast, happy) carries a heart.
One tree, two trees, three
木 tree, 林 woods, 森 forest. The most satisfying three characters in the language.
Guess the meaning
Brand-new characters students have never seen. Using only the radical, they guess the rough meaning — and are right surprisingly often.
The sound half
The 青 family, read aloud together. Students discover that one component is carrying the pronunciation, then hunt for the same trick in 妈 and 河.
If Chinese has felt too hard, this is the turn
Grade 2 is where character writing stops being a novelty and starts being work, and it’s the most common point for a child to decide Chinese is impossible. This unit is the answer. It converts memorisation into reasoning — instead of a thousand unrelated shapes, students see a few hundred parts recombining. If your student has been struggling since the autumn, it is entirely reasonable to bring this unit forward and teach it early. Nothing in Units 6 to 8 depends on it.
Unit 9 progress check
A light, no-pressure way to see what’s sticking:
- Can your child find the radical in 河 and 吃?
- Shown an unknown character with 氵, do they guess it involves water?
- Can they name four radicals and their meanings?
The second question is the one that matters. Guessing from a radical is the skill that carries a student to 900 characters.
