Chinese character forms studies the external structure of Chinese characters, i.e. strokes, components and whole characters and their structural relations on the pure dimension of forms or appearances. The internal structure of Chinese characters (Pinyin: hànzì nèibù jiégòu; Traditional Chinese: 漢字的內部結構; Simplified Chinese: 汉字内部结构) studies the relationship between the forms, sounds and meanings of the characters, thereby explaining the rationale for character formation.
In the analysis of internal structures, Chinese characters are decomposed into internal structural components in relations with the sound and meaning of the character.
The character-building units obtained by analyzing the external structure of Chinese characters are external structural components. In internal structures, Chinese characters are analyzed according to the rationale of character formation, and the basic unit of character formation are internal structural components, or internal components in short, also called pianpang (偏旁） or characters (字符).
In most cases, the components of internal structure of a Chinese character is similar to the first-level components in external structure, for example, character 江 is decomposed into 氵 and 工 in both analyses. However, they are not always the same. For example, character "腾" is decomposed according to the internal structure as "semantically related to '马' and phonetically related to '朕'", in a semi-surrounding structure; while the external analysis then simply split it according to the left-right structure.The external structure splitting method is used only when the internal structure analysis cannot be decomposed according to the character formation rational.
According to their sound-meaning relationship with the whole character, internal components can be classified into three categories: semantic component （義符, 义符, 意符, 意旁 or 形旁）, phonetic component (音符, 音旁 or 聲旁) and pure (form) component (記號, 符號).
In Shuowen Jiezi, Xu Shen proposed the six categories (六書; liùshū; 'Six Writings') for the formation of Chinese characters, including
The traditional Six Writings classification presupposed that each component in a Chinese character can either represent the sound or meaning of the character. But, after the long evolution of the Chinese writing system, quite a few of components can no longer effectively play the roles. For example, component 又 in character 邓 and 鸡 can neither represent sound nor meaning, and has become pure form component.
From the internal structure point of view, modern Chinese characters are composed of semantic components, phonetic components and pure form components.These three types of components are used in combination to form the seven structures of modern Chinese characters: semantic component characters, phonetic component characters, pure form component characters, semantic-phonetic characters, semantic-form characters, phonetic-form characters, and semantic-phonetic-form characters.
Semantic component characters, or simply semantic characters, are composed of semantic components.
Single semantic component characters are composed of one semantic component, and most of them correspond to pictograms and simple ideograms in the traditional six writings. For example:
Multi-semantic-component characters are composed of two or more semantic components. They include the compound ideographs in the traditional Six writings. For example,
Most multi-semantic component characters contain two semantic components, for example,
Some characters composed of three semantic components, for example,
Some characters repeat the same semantic components, for example,
Some are simplified characters:
There are some special cases
叵 (can not): turn 可 (can) to the opposite (right) side. (Shuowen)乌 /烏 (crow, a pure black bird), 鳥/鸟 cannot see its eyes. (Note by Duan Yucai)冇 (none, not have): 有 (have) taken away "二" (content).
A phonetic component character, or shortly phonetic character, is composed of one or more phonetic components.
A single phonetic component character may be used to express an phonetic-loan meaning while its original or basic meaning is still understood by people. For example:The pronunciation of character "花" meaning "spending" is the same as that of the "花" which means "flower" in its original meaning. The latter can be regarded as the phonetic component of the former.A single phonetic component character can also represent a syllable in a transliterated foreign word, for example, the characters in words "打" (dá, dozen) and "馬達" (mǎdá, motor).
Multi-phonetic component characters were produced during the development of writing systems. For example:
"新" (xīn) was originally a semantic-phonetic character, but its modern meaning of "new" has nothing to do with the original semantic component of "斤" (jīn, 0.5 kg), but the sound are similar. In this way, "新" (xīn) then has two phonetic components: "亲" (qīn) and "斤" (jīn).
"耻” (chǐ, shame) used to be written as 恥 which is a semantic-phonetic character. The semantic component 心 (heart) has become 止 (zhǐ, stop), "耻” (chǐ) then has two phonetic components, "耳" (ěr) and 止 (zhǐ).
A pure form character is composed of one or more form components, which neither represent the sound nor the meaning of the characters.
These characters are composed of single pure form components. Many of them were originally ancient pictographic characters, but due to the evolution of the glyphs, they no longer look like the object represented. For example:
After tracing to the origin of this kind of characters, it is easy to associate them with the things they represent and obtain the correct meanings.
Some characters with single form components are borrowed characters from ancient times. For example:
Some combined characters have been simplified and become single form component characters.
These characters consist of two or more pure form components. Some of these characters came from ancient pictographic characters, but later became non-pictographic. For example,
Some came from ancient semantic-phonetic characters, and the semantic and phonetic components of these characters have lost their functions. For example:
Some are simplified characters. For example:
Some are from ancient ideographic characters. For example:
Semantic-phonetic characters (also called "phono-semantic characters", 意音字, 形聲字) consist of semantic components and phonetic components. The semantic component indicates the category of word meaning, and the phonetic component indicates (or prompts) the pronunciation of the character.
The phonetic components of some semantic-phonetic characters are of exactly the same pronunciation as the whole character. For example,
The sounds of the character and its phonetic component are the same except in tones. For example,
According to the experiment by Li (1993), among the 7,000 characters in the "Modern Chinese Common Character List", 5,631 are of semantic-phonetic structures. Considering that there are 479 polyphonic characters, the number of semantic-phonetic structures increases accordingly to 6,110. Among them,there are 2292 items with characters and components of the same pronunciations and tones, accounting for 37.51%. There are 1110 items with characters and components of the same pronunciations but different tones, accounting for 18.17%
The phonetic components of some characters are also semantic components. For example:
Some phonetic or semantic components have some parts omitted. For example:
or semantic 老, phonetic 旨 with upper part omitted.
There are six combinations of semantic components and phonetic components:
Modern character-making mainly inherits traditional character-making methods, but there are also innovations, such as combining the sounds and forms of two characters. For example,
Semantic-phonetic characters account for more than 90% in ancient Chinese characters.According to statistics, among the 7,000 modern common characters of the simplified Chinese character writing system, semantic-phonetic characters account for only 56.7%. The traditional Chinese character system is slightly higher.
Semantic-form characters are composed of semantic components and pure form components. They are also called semi-semantic components and semi-pure form components.
Many of these characters were originally semantic-phonetic characters. Due to subsequent changes in the pronunciation of the phonetic components or of the characters, the phonetic components could not effectively represent the pronunciation of the character and became pure form components. For example:
Due to the simplification of Chinese characters, some phonetic components are no longer effective. For example:
Some are modified from ancient pictographic characters. For example:
Phonetic-form characters are composed of phonetic components and pure form components. This type of characters mainly comes from ancient semantic-phonetic characters, and the semantic components lost their semantic roles and became pure form components. For example,
A semantic-phonetic-form character consists of all three kinds of components: semantic, phonetic and pure form components. For example,
Semantic-phonetic-form characters are very rare and the examples above are not quite persuasive. Whether it can be justified as an internal structural category remains to be further studied. (If not, the classification above can also be called the "New Six Writings")
According to Yang, among the 3500 frequently used Chinese characters of his experiment, semantic component characters are the least, accounting for about 5%;pure form component characters account for about 18%;semantic-form and phonetic-form characters account for about 19%.The largest group is semantic-phonetic characters, accounting for about 58%.
Using texts to record a language is to establish a fixed connection between text symbols and language words. If this connection is arbitrary, it is irrational; if there is a reason for it, it is rational.
English words are mainly a phonetic text, and their rationality mainly lies in using a combination of letters to represent the pronunciation of the corresponding word. Chinese characters are phonetic and semantic characters, and their rationality is mainly reflected in the use of phonetic components to express sounds and semantic components to express meanings.
Generally speaking, words with higher rationality are easier to learn and use. Because the unreasonable parts often require rote memorization. There are thousands of modern Chinese characters, and it is unrealistic to require every character to have high rationality.
The phonetic components and semantic components are related to the pronunciation and meaning of the character, so they are reasonable; the pure form components are not related to the pronunciation or meaning of the character, and they are irrational.Therefore, semantic component characters, phonetic component characters, semantic-phonetic characters, pure form component characters are irrational characters. And the other characters are semi-rational characters.
Su defined the rationality of a character set as the proportion of rational components in all the internal components.
The formula is: Rationality = (actual rationality value)/(maximum rationality value).
Professor Su's preliminary experiment results showed the rationality of modern Chinese characters to be about 50%, which is far lower than that of ancient Chinese characters.
Rational characters are easier to learn and often arouse students' interest.In modern Chinese teaching, in order to enhance the rationality of Chinese characters, the traceability method is often used. For example: "日 (sun), 月 (moon), 山 (mountain), 水 (water), 牛 (cow), 羊 (sheep), 网 (net), 木 (wood), 目 (eye), 門 (door) and 刀 (knife)” are all pictographic characters from the etymology point of view. If the teacher makes some etymology analysis with the evolution of glyphs, he/she may achieve twice the result with half the effort.
The traceability analysis mentioned here is only for the convenience of teaching, rather than a comprehensive analysis of the origin and evolution of Chinese characters.There is no need to trace the origin of characters that can be explained from the current situation; only for those characters where the rationale cannot be seen from the current situation and it is easy to trace the origin to explain the rationale, this method can be employed.
