The Radical (bushou 部首) Systems

Apr 5, 2011 © Ulrich Theobald

The classifiers, determinants or radicals (bushou 部首) of a Chinese character serve to categorize words according to their meaning and to place them into a dictionary. The advantage of a radical is that one does not have to know the pronunciation of the character. For most characters, there is no problem to be categorized. But especially characters that are not compounded of a phonetical (shengfu 聲符) and a classifying part (xingfu 形符), are not easy to be classified in such a system. For example, shall the character for "heaven" 天 be classified under "great" 大 or under "one" 一? Having a closer look at some characters, wrong attributions can easily be found, for instance the character for dao 到 "arriving" seems to be compounded from a standing "knife" 刀 to the right and the character 至 as a second part. Indeed, all characters deriving from the radical "knife" have the same shape. But looking at the meaning of the character, we see that in fact, the "knife" is not the radical, but the phonetical part of the character (pronounced dao), and the left part is in fact the radical zhi "arriving". Some writing styles also create the problem to recognize the real radical, for example 荊 jing: is the radical the "top grass" 艸 or the "standing knife" 刀?
The dictionary most accurately describing the characters and their radicals is the Late Han dictionary Shuowen jiezi 說文解字 by Xu Shen 許慎 (d. 147 AD). Xu attributed all characters to 540 radicals. Many of these radicals have only few characters depending on them (like xi "binding together, connecting": 孫 sun grandson, 綿 mian brocade, 繇 yao following up), some Shuowen radicals even stand alone for themselves, like the first of terrestrial branches, 甲 jia. And one can really argue if the character 炎 yan "gleaming", consisting of two "fire" 火, is a radical for its own or rather belongs to the radical 火 huo (one fire). The system of 214 radicals came up during the late Ming dynasty, when characters like 孫 sun "grandson" were rather attributed to the radical zi 子 "son". The first dictionary using the 214 radical system was Mei Yingzu's 梅膺祚 Zihui 字彙 "Character treasure" from 1615, containing more than 30.000 characters. The most famous dictionary using them is the Kangxi dictionary Kangxi zidian 康熙字典 from 1716.

Even the reduction of radicals from 540 to 214 left behind a lot of work for people wanting to be expert in knowing the radicals of all characters. Modern dictionaries therefore have created their own system of radicals, mostly according to the shape of the Chinese character. Characters like 哉 zai (an exclamation particle), 栽 zai "planting", 戴 zai "loading", 裁 cai "tailoring" can now easily be found under the radical - what is actually the phonetical part of these characters - instead of the traditional radicals kou "mouth", mu "tree", che "cart", or yi "clothing". 奉 feng "receiving with respect", 奏 zou "reporting to the throne", 春 chun "spring", 泰 tai "great", 秦 qin (a kind of millet), are now all headed under the radical , while their traditional radicals are gong "raised hands", tao "going forward" (the 214 radical system attributes feng and zou to the radical da "great"), ri "sun" (the Shuowen jiezi only knows the character 萅 for "spring"), shui "water", and he "grain". See also the theme simplification of characters.
Some radicals have a different shape if they stand alone as a word, and as a radical:

  • 刀 "knife" is written as a "standing knife" (lidao 立刀) to the left 到 and standard if on the bottom 券
  • 心 "heart" is written as a "standing heart" (shuxin 豎心) to the left 情 or with four dots if on the bottom 恭, but sometimes written standard 愛寧
  • 人 "man" is written as a "standing man" (danliren 單立人) to the left 仁 or relatively wide if on the bottom 兒
  • 手 "hand" is written with three strokes (tishoupang 提手旁) to the left 抱 or standard if on the bottom 擎
  • 攴 "whip" is normally written like (fanwen 反文) 故, and only seldom written standard 敲
  • 水 "water" is normally written with three dots (sandianshui 三點水) 江 and standard if on the bottom 汞
  • 火 "fire" is written standard if to the left or on the bottom 烤炃 and with four dots (sidian 四點) if on the bottom, but sometimes written standard 焚
  • 犬 "dog" is written with a special shape 狄 called quanyou 犬猶
  • 玉 "jade" is written like a king 王 if to the left, but standard if on the bottom 璧
  • 爪 "claw" is written in small dots 爭 if on the top
  • 网 "net" is written like a horizonal eye 置 (sizitou 四字頭)
  • 艸 "grass" is written with three (or four) strokes on the top (caozitou 草字頭) 華
  • 肉 "meat, flesh, organ" is written like 月 a moon 肺
  • 示 sacral matters are written with four (or five) strokes to the left 福 and standard on the bottom 祟
  • 衣 "clothing" is written with five strokes to the left 衫, and sometimes separated in bottom and top 袞
  • 辵 "walking" is written with four (or three) strokes (zouzhi 走之) 近
  • 阜 "dam" and 邑 "town" are written with three (two) strokes in the shape of an ear (erdao 耳刀) 邯阻
  • 食 "eating" is written with one stroke less 飯
The list below gives an overview over the 214 radicals with their meaning and examples how characters with these radicals look like. The characters in round brackets () are examples for simplified forms whose traditional forms have other radicals.
