✍️ Chinese Writing, Radicals

Learn the building blocks
of Chinese characters

Chinese characters are not random, they are built from small pieces called radicals. Once you know the 10 most common ones, you will start recognising them in hundreds of words!

🧒 Ages 6–18 🧱 10 key radicals 📖 Real word examples 🎯 Mini quiz

What is a radical? 🤔

A radical (部首 bùshǒu) is the root part of a Chinese character. Think of it like a LEGO brick, you combine bricks to build something bigger. The same radical can appear on the left, right, top or bottom of a character, and it often gives you a clue about the meaning!

💡

Spot the pattern

When you see 河 (river), 海 (sea) and 洗 (wash), they all have 氵 on the left. That is the water radical!

🔄

Two forms, one radical

Radicals often change shape depending on position. 火 (fire) becomes 灬 at the bottom of a character.

Every radical you learn is a clue to dozens of new characters. The more you know, the easier it gets!
