Illustration of the most useful Chinese radicals to learn characters

Learning Chinese may seem overwhelming when you think of just how many thousands of characters there are, but we’ll let you in on a secret: radicals. These key components give us clues about a word’s meaning and make it easier to understand and memorize them.

Today we’ll dig into the 7 most useful radicals, which you’ll find in more than 5,400 characters (yes, you read that right!). That’s 15-20% of the most commonly used characters.

1. 木 [mù]: wood/tree

We find this radical in objects that were traditionally built with wood, as well as in words related to trees.

Examples:

  • 林 [lín]: forest (two trees together)
  • 森 [sēn]: dense forest (three trees)
  • 桌 [zhuō]: table (木 + 卓, where 卓 indicates something tall and upright)
  • 椅 [yǐ]: chair (木 + 奇, phonetic component)
  • 板 [bǎn]: board (木 + 反)
  • 桥 [qiáo]: bridge (木 + 乔, suggests elevation)

2. 火 [huǒ]: fire

This radical can take two forms: 火 and 灬. The first is usually placed to the right of the character and the second underneath it. It can be found in words related to heat, light, energy, fire…

  • 灯 [dēng]: lamp (火 + 丁, old nail used in lamps)
  • 热 [rè]: hot
  • 烧 [shāo]: to burn; to cook
  • 炎 [yán]: flame (two fires together)
  • 烤 [kǎo]: roast (火 + 考, phonetic component)

3. 氵: water

Whenever we see this in a character, we know it has something to do with liquid and actions that involve water.

  • 河 [hé]: river
  • 海 [hǎi]: sea 
  • 洗 [xǐ]: to wash
  • 泳 [yǒng]: to swim
  • 泪 [lèi]: tear (氵 + 目, eye)

4. 口 [kǒu]: mouth

We find this in characters relating to sounds and things we do with our mouths. It often also represents "entrances" or "spaces".

  • 吃 [chī]: to eat 
  • 叫 [jiào]: to call, to shout
  • 唱 [chàng]: to sing
  • 喝 [hē]: to drink
  • 问 [wèn]: to ask
  • 国 [guó]: country

5. 日 [rì]: sun/daytime

This one appears in characters related to time, light or sun.

  • 明 [míng]: bright (日 + 月, moon)
  • 时 [shí]: weather (日 + 寸, unit of measure)
  • 早 [zǎo]: early
  • 晴 [qíng]: sunny (日 + 青, phonetic component)
  • 星 [xīng]: star

6. 艹: grass/plants

We find this radical in words related to plants, flowers and vegetables.

  • 花 [huā]: flower

  • 茶 [chá]: tea
  • 菜 [cài]: vegetables
  • 药 [yào]: medicine (from medicinal herbs)

7. 冫 [bīng]: ice

Finally, when we come across a character with this radical, we know that the word will mean something cold or freezing.
