Chinese character internal structures

Semantic component characters, or simply semantic characters, are composed of semantic components.[8]

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:[8]

• 田 (field), 井 (well), 門 (door), 网 (net) are ancient pictograms, and 门 (door), 伞(umbrella) are modern pictograms.
• 一 (one), 二 (two), 三 (three), 刃 (blade) are ancient simple ideograms, and 丫（branch, fork), 凹 (concave), 凸 (convex), and 串 (string) are later simple ideograms.

Multi-semantic-component characters are composed of two or more semantic components.[9] They include the compound ideographs in the traditional Six writings.[10] For example,

Most multi-semantic component characters contain two semantic components, for example,

• 信 (trust): semantic components 人 (people) and 言 (words), trust what people say.
• 尖 (pointed, sharp, tip): 小 (small) at the top and 大 (large) at the bottom.
• 拿 (take): 合 (close) your 手 (hands) together to take.

Some characters composed of three semantic components, for example,

• 掰 (break apart): Separate (分) something with both hands (手).
• 晶 (brilliant, crystal): three 日 (suns) are very bright.

Some characters repeat the same semantic components,[11] for example,

• 从 (follow): Indicates that one 人 (person) follows another person.
• 炎 (flame): Two 火 (fire) represents rising flames.
• 森 (large forest): Three 木 (trees) means there are many trees.

Some are simplified characters:

• 尘 (dust): 小 (small) 土 (soil) particles, representing dust.
• 灭 (extinguish): Use 一 (like a cover) to suppress 火 (fire).
• 泪 (tears): 氵(water) from 目 (eyes).

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.[8]

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, 0.5kg), 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).

• 乒乓（pīngpāng, ping pong), both forms and sounds of the two characters are derived from 兵 (bīng, soldier) with similar sounds.

A pure form character is composed of one or more form components, which neither represent the sound nor the meaning of the characters.[12]

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:

• 日: The 日 character in modern regular script is no longer of round shape.
• 月: It has become a ladder shape.
• 魚: Not quite like a fish now.

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:

• 我: In oracle it is like a weapon with a blade shaped like a saw, and was later used as a first-person pronoun. And in modern Chinese, the original meaning is lost.
• 方: "Shuowen Jiezi" believes that the original meaning is a kind of boat, which has been borrowed to express the shape of "square".
• 而: The ancient character was like a beard, now has been borrowed to be a conjunction in modern Chinese.[13]

Some combined characters have been simplified and become single form component characters.

• 广: The traditional Chinese character is "廣".
• 农: Traditional character "農".
• 书: Traditional character "書".
• 专: Traditional character "專".
• 门: Traditional character "門".

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,

• 角(horn): This character in oracle bone script looks like an ox horn
• 鼎(tripod): The oracle bone inscriptions are in the shape of a tripod.
• 鹿 (deer): Oracle resembled a deer.

Some came from ancient semantic-phonetic characters, and the semantic and phonetic components of these characters have lost their functions. For example:

• 騙 (piàn)： It originally meant to jump on the horse. Now means deception, and semantic component 馬 (horse) and phonetic 扁 (biǎn) have become pure forms.
• 特: semantic 牛 and sound 寺, it originally refed to bull, but now it means "special" and "unusual", and both components are pure forms.
• 穌：semantic 禾 (crop) and sound 魚 (yu2, fish), Duan Yucai's note in Shuowen says: "If the grain is scattered, pick it up with a loaf." The character now expresses the meaning of awakening, or is used in a person's name.

Some are simplified characters. For example:

• 头 (head): The traditional Chinese character is “頭”, semantic component 頁 and phonetic component 豆. The simplified character component 大 and the two dots are pure form components.

Some are from ancient ideographic characters. For example:

• 射 (shooting): The word "射" in oracle bone and bronze inscriptions is like pulling a bow and shooting, now neither 身 nor 寸 can express the sound or meaning of 射.
• 至 (to): in oracle bones is like an arrow shooting to the ground. According to the current glyph, the original meaning can no longer be seen, let alone the modern meaning of the word.

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.[14]

The phonetic components of some semantic-phonetic characters are of exactly the same pronunciation as the whole character.[15] For example,

• 搬 (bān, move): 般 (bān).
• 銅 (tóng, copper): 同 (tóng).
• 辯 (biàn, debate): 辡 (biàn).

The sounds of the character and its phonetic component are the same except in tones. For example,

• 巍 (wēi, tall): 魏 (wèi).
• 拥 (yōng): 用 (yòng).
• 帳 (zhàng, account): 長 (zhǎng).

According to the experiment by Li (1993),[16] 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:

• 娶 (qǔ, marry (a wife)): semantic 女 (female), phonetic 取 (qǔ), 取(take) also express the meaning.
• 駟 (sì, four horses of a cart): semantic 馬 (horse), phonetic 四 (sì), 四 (four) also represents meaning.
• 懈 (xiè, slack): 解 (xiè, scattered) represents sound and meaning.

Some phonetic or semantic components have some parts omitted. For example:

• 珊 (shān, coral): 冊 is 删 (shān) with the right part omitted.
• 氮 (dàn, nitrogen): 炎 is 淡 (dàn) with the left part omitted.
• 夜 (yè, night): semantic 夕, the rest is 亦 (yì) with some strokes omitted.
• 耆(qí, senior over sixty years old), semantic 老 with lower part omitted, phonetic 旨[17]

or semantic 老, phonetic 旨 with upper part omitted.[18]

There are six combinations of semantic components and phonetic components:

• Left meaning (semantic) and right sound (phonetic), such as 肝 (gān, liver), 惊 (jīng, fear), 湖 (hú, lake);
• Right meaning and left sound, such as 鵡 (wǔ, parrot), 剛 (gāng, firm), 甥 (shēng, nephew);
• Upper meaning and the lower sound: 霖 (lín, rain), 茅 (máo, grass) and 竿 (gān, pole);
• Lower meaning and upper sound: 盂 (yú， bowl), 岱 (dài, Mount Tai), 鯊 (shā, shark);
• Outer meaning and inner sounds: 癢 (yǎng, itch), 園 (yuán, garden), 衷 (zhōng, heart), 座 (zuò, seat), 旗 (qí, flag);
• Inner meaning and outer sound: 辮 (biàn, braid), 悶 (mèn, dull), 摹 (mó, imitation).

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,

• 甭 (béng, no need), meaning 不用 (bùyòn, no need), and sound derived from “bùyòng”.
• 巰 (qiú, compound of hydrogen and sulfur), 氫 (qīng, hydrogen) + 硫 (liú, sulfur), with parts omitted.

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%.[19] 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.[20][21]

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:

• 布 (bù, cloth): used to have semantic (component) 巾 (scarf) and phonetic 父 (fù), the phonetic component is no longer 父.
• 江 (river): used to have semantic 水 and phonetic 工, now in the Mandarin 工 (gōng) does not pronounce 江 (jiāng).
• 急 (jí, urgent): used to have semantic 心 (heart) and sound 及 (jí). Now the upper component no longer looks like 及.

Due to the simplification of Chinese characters, some phonetic components are no longer effective. For example:

• 灿(càn, brilliant), not read as 山 (shān).
• 鸡(jī, chicken), not read as 又 (yòu).
• 环 (huán, ring), not read as 不 (bù).

Some are modified from ancient pictographic characters. For example:

• 栗 (lì, chestnut): The upper part of the ancient Chinese character resembles the fruit on a chestnut tree. Now 覀 is a pure form component.
• 泉 (quán, spring): The oracle character looks like water flowing out of a cave. Now it has become components 白 (bái, white) and 水 (shuǐ, water). 白 is a pure form component.
• 桑 Mulberry: in oracle script the upper part of 桑 resembles lush branches and leaves. The current 叒 is a pure form component.

Phonetic-form characters are composed of phonetic components and pure form components.[22] 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,

• 球 (qiú, ball)： Originally refers to a kind of beautiful jade, with semantic component 王（玉, jade). Later, it was borrowed to represent a ball, and then extended to a round three-dimensional object, and 王（jade) became a pure form component. And 求 （qiú） remains a phonetic component.
• 笨 (bèn, stupid): Originally refers to the inner white layer of bamboo, with semantic component 竹 and phonetic 本. Later, the character was borrowed by sound to mean stupid.
• 华：This is a simplified character with phonetic 化, and 十 is a pure form component.

A semantic-phonetic-form character consists of all three kinds of components: semantic, phonetic and pure form components. For example,[12]

• 岸 (àn, bank, shore), originally had semantic component ⿱山厂 and phonetic 干 (gàn). In modern Chinese, ⿱山厂 is not a character or radical with a sound or meaning, but 山 can still express meaning, while 厂 remains a pure form component.
• 聽 (tīng, listen), semantic 耳 (ear) and phonetic 壬 (ting3). In modern Chinese characters, the right part has become a pure form component.

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,[20] 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%.
