Water’s Flow: 水 and the 氵 Radical

See how the kanji for water shapes words like sea and alcohol, and why it sometimes hides as three drops.

JLPT N5 · 21 Aug 2026

The Picture of 水

If you look at the kanji 水(みず, water), you can almost see a stream with splashes on both sides. The middle line is the current, and the little strokes are droplets. That's the picture: a river flowing between banks.

Over time, the drawing got tidied up. The wavy lines became straight, and the droplets became strokes. But the idea stayed: water in motion.

When Water Becomes 氵

When water appears on the left side of a kanji, it often turns into three drops: 氵. This is the radical for water, and it signals that the character has something to do with water, liquid, or flow.

For example, 海(うみ, sea)is made of 氵 plus 毎(every). The sea is the water that is everywhere? Actually, the right side gives a hint of sound, but the meaning is clear: a huge body of water. When you see 氵, you know it's wet.

Another familiar one is 酒(さけ, alcohol). The left side is 氵, because alcohol is a liquid. The right side is 酉, which is a jar. So 酒 is the liquid in a jar. That's how the ancient Chinese saw it: a fermented drink stored in a vessel.

Three Drops, Many Words

You'll find 氵 in many N5 words. Here are a few you might already know:

Water in Action

Water is not just a noun; it's also a verb. 飲む(のむ, to drink)has 食 (eat) on the left and 欠 (yawn) on the right, but the action of drinking is about taking in liquid. Actually, 飲む has no 氵, but it's still about water.

But the radical 氵 is most common. When you see it, you can guess the meaning is related to water or liquid. That's a powerful tool for reading.

Water Shapes Meaning

Sometimes water is not literal. For example, 活気(かっき, energy)has 氵 in 活(かつ, lively). The original meaning of 活 is the sound of water? No, it's more about flowing. So 活気 is the flow of life, the energy that moves.

In your city, your city, you might see water in a river or a tap. The same kanji 水 is used everywhere, from 水曜日(すいようび, Wednesday, the day of water)to 水着(みずぎ, swimsuit).

The Radical's Power

Knowing 氵 helps you unlock dozens of kanji. If you see a character with three drops on the left, you can often guess it's about water or a liquid. That's a shortcut to meaning.

Yesterday, you learned about 心 and its radical forms. Today, you've seen how water flows through 水 and 氵. Each radical is a key that opens a door.

The Flow Continues

Water is essential, but so is fire. Tomorrow, you'll see how fire is drawn as four dots at the bottom of a kanji. How do you think that looks? And what happens when fire and water meet? That's a story for tomorrow.

For now, remember: 水 is the picture of a stream, and 氵 is its radical form. When you see it, think of flow.

Your Turn

Try to spot 氵 in the world around you. Look at a bottle of 水, or a sign for 海. The more you see it, the more familiar it becomes.

That's the beauty of kanji: each one is a picture, and each radical is a piece of that picture. You're putting the pieces together, one day at a time.
