The heart radical: 心 and 忄

心 xīn means heart and has four strokes. It sits at the bottom of characters like 想 xiǎng (think) and becomes the three-stroke 忄 on the left, as in 忙 máng (busy) and 怕 pà (afraid).

Three forms to recognize

The ⺗ form is less common. It appears at the bottom of a small number of characters such as 恭 gōng (respectful) and 慕 mù (admire). You only need to recognize it; learning 心 and 忄 first is enough for most beginner reading.

Chinese speakers often call 忄 竖心旁 shùxīnpáng, "standing heart side," and the bottom 心 心字底 xīnzìdǐ.

Thought and feeling

In Chinese, 心 has long been associated with both emotion and thinking, so you will find it in words for both:

• 想 xiǎng: think, want, miss someone
• 思 sī: think
• 意 yì: meaning, intention
• 忙 máng: busy
• 怕 pà: afraid
• 情 qíng: feeling
• 懂 dǒng: understand

These characters are read xiǎng, sī, yì, máng, pà, qíng, and dǒng. None is pronounced xīn. Learn each reading on its own.

Not every emotion has a heart

Many feeling words use other components:

• 笑 xiào (laugh) has bamboo 竹 on top.
• 哭 kū (cry) has two 口 mouths.
• 喜 xǐ (happy) has no heart.
• 爱 ài (love) in simplified Chinese has no 心, though the traditional form 愛 does.

So 忄 or 心 is a good hint toward mind or mood, but a missing heart tells you nothing. Some heart characters also have meanings that seem far from feelings, like 快 kuài (fast).

Avoid neat origin stories

You may read stories explaining every heart character, for example why 忙 combines heart with 亡 wáng. Some are traditional explanations, some are modern inventions. If a story helps you remember, use it as a memory hook, not as history.

Recognition drill

Find the heart component in each character and say which form it takes: 念 快 怕 感 恭 情.
