In the traditional Chinese character structure theory, Chinese characters are divided into two categories according to their constituent units: single words and combined words. Monographs (Sun, Moon, Cattle, Sheep, Up and Down, etc. ) is composed of strokes, and combined words (Xie, Qu, She, Sen, Gong, Box, etc. ) is composed of radicals.
Therefore, radical is a name in the traditional Chinese character structure theory, which refers to the components of "Liushu" that are intended to understand, pictophonetic characters and phonetic, ideographic or phonetic characters. For example, Qi and Mu in Hugh, Er and You in Qu, Jia and Mu in Jia, and so on. Radicals are composed of strokes, which are one level higher than strokes. Radicals can also be classified according to different standards. For example, whether it is word-shaped, whether it is compound and separable, and so on.
The six-book analysis method is not completely applicable to modern Chinese characters, so the philology circle has constructed a new system of Chinese character structure analysis, namely: strokes-components-whole characters. Different from before, the new system puts forward "components". Components, like radicals, are the basic structural units of Chinese characters between strokes and whole characters. Different from radicals, it focuses on the glyph structure of all modern Chinese characters, not only the pictophonetic characters in the "Six Books", but also the specific word-formation components that express sounds and meanings. For example, the simplified words "two" and "ㄒ" in the word "cloud" and "ㄧㄧ", "you" and "earth" in the word "vertical" are not all radicals, but they are all components. Another example is that "Fu" consists of four parts: Fu, Fu, Chen and Cun. It bypasses uncommon words and difficult radicals. Decomposing Chinese characters into components can reduce the basic structural units of commonly used Chinese characters to five or six hundred, greatly reducing the difficulty of Chinese information processing.
Radical is the word-forming component of compound words. The ancients called the left and right sides of Chinese characters with left and right structures "pian" and "bian". Now, all parts of the combined Chinese characters are collectively called parallel.
Chinese characters are mostly pictophonetic characters, which are composed of pictophonetic characters and homophonic characters. Therefore, "radical" mainly includes pictophonetic characters and homophonic characters. For example, the word "Yu" consists of two radicals, Yan and Wu. The word "basin" consists of two radicals: "fen" and "pan bottom"; The word "Wen" consists of two radicals: the door frame and the mouth.
