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 pen character consists of two radicals: the sub-character and the bottom character; Interrogative words are composed of two parts: door frame and mouth.
Radicals are often said together, so some people think that "radicals" and "radicals" are the same thing, which is a misunderstanding. Radical and radical are two different concepts, although there are some connections. Radicals are radicals, but radicals are not all radicals.
Knowledge expansion:
The word "radical" is often mentioned when analyzing glyphs. The first primary school Chinese book edited and published by People's Education Publishing House contains a list of radical names. So what is "radical"? Generally speaking, radicals are ideographic radicals. Radicals are also radicals, but radicals are not necessarily radicals, and radicals and radicals are the whole and part relationship.
Among the radicals, the number of radicals is very small, but the commonly used radicals exceed 100, and the number of radicals listed in the above-mentioned radical name table is 99. A large number of radical capitals are phonetic components, mainly phonetic components, and there are more than 1000 commonly used.
Nearly 90% of syllables are monosyllabic words, such as "Bian", "Jia" and "Gu". In Chinese teaching in primary schools, those syllables with strong word-formation ability are called "basic words".
Calling the ideographic radical "radical" originated from an ancient dictionary represented by Shuo Wen Jie Zi. In ancient dictionaries, Chinese characters were classified according to their glyphs, and words with common glyphs were classified as a part, with common glyphs as titles.
It is placed at the top of this participle, so it is called "radical" because it is at the head of a department. For example, the words "Ma", "Mei", "Miao" and "Gu" all have the same word "female", and "female" is the radical of these words.
