chữ nôm

Chữ Nôm (, ) is a logographic writing system formerly used to write the Vietnamese language. It uses Chinese characters to represent Sino-Vietnamese vocabulary and some native Vietnamese words, with other words represented by new characters created using a variety of methods, including phono-semantic compounds. This composite script was therefore highly complex and was accessible to the less than five percent of the Vietnamese population who had mastered written Chinese.

Although all formal writing in Vietnam was done in classical Chinese until the early 20th century (except for two brief interludes), chữ Nôm was widely used between the 15th and 19th centuries by the Vietnamese cultured elite for popular works in the vernacular, many in verse. One of the best-known pieces of Vietnamese literature, '' The Tale of Kiều'', was written in chữ Nôm by Nguyễn Du.

The Vietnamese alphabet created by Portuguese Jesuit missionaries, with the earliest known usage occurring in the 17th century, replaced chữ Nôm as the preferred way to record Vietnamese literature from the 1920s. While Chinese characters are still used for decorative, historic and ceremonial value, chữ Nôm has fallen out of mainstream use in modern Vietnam. In the 21st century, chữ Nôm is being used in Vietnam for historical and liturgical purposes. The Institute of Hán-Nôm Studies at Hanoi is the main research centre for pre-modern texts from Vietnam, both Chinese-language texts written in Chinese characters () and Vietnamese-language texts in chữ Nôm.

Etymology

The Vietnamese word 'character' is derived from the Middle Chinese word , meaning ' hinesecharacter'. The word 'Southern' is derived from the Middle Chinese word , meaning 'south'. It could also be based on the dialectal pronunciation from the South Central dialects (most notably in the name of province of '' Quảng Nam'', known locally as ''Quảng Nôm'').

There are many ways to write the name in chữ Nôm characters. The word may be written as , , , , , , , or , while is written as .

Terminology

is the logographic writing system of the Vietnamese language. It is based on the Chinese writing system but adds a large number of new characters to make it fit the Vietnamese language. Common historical terms for chữ Nôm were (, 'national sound') and (, 'national language').

In Vietnamese, Chinese characters are called ( 'Han characters'), ( 'Confucian characters', due to the connection with Confucianism) and uncommonly as ( 'Han characters'). ''Hán văn'' () refers literature written in Literary Chinese.

The term ( 'Han and chữ Nôm characters') in Vietnamese designates the whole body of premodern written materials from Vietnam, either written in Chinese () or in Vietnamese (). Hán and Nôm could also be found in the same document side by side, for example, in the case of translations of books on Chinese medicine. The Buddhist history ''Cổ Châu Pháp Vân phật bản hạnh ngữ lục'' (1752) gives the story of early Buddhism in Vietnam both in Hán script and in a parallel Nôm translation. The Jesuit Girolamo Maiorica (1605–1656) had also used parallel Hán and Nôm texts.

The term ( 'national language script') refers to the Vietnamese alphabet in current use, but was used to refer to chữ Nôm before the Vietnamese alphabet was widely used.

History

Chinese characters were introduced to Vietnam after the Han dynasty conquered Nanyue in 111 BC. Independence was achieved after the Battle of Bạch Đằng in 938, but Literary Chinese was adopted for official purposes in 1010. For most of the period up to the early 20th century, formal writing was indistinguishable from contemporaneous classical Chinese works produced in China, Korea, and Japan.: "Because the Chinese characters were pronounced according to Vietnamese preferences, and because certain stylistic modifications occurred over time, later scholars came to refer to a hybrid "Sino-Vietnamese" (Han-Viet) language. However, there would seem to be no more justification for this term than for a fifteenth-century "Latin-English" versus the Latin written contemporaneously in Rome."

Vietnamese scholars were thus intimately familiar with Chinese writing. In order to record their native language, they applied the structural principles of Chinese characters to develop chữ Nôm. The new script was mostly used to record folk songs and for other popular literature. Vietnamese written in chữ Nôm briefly replaced Chinese for official purposes under the Hồ dynasty (1400–1407) and under the Tây Sơn (1778–1802), but in both cases this was swiftly reversed.

Early development

The use of Chinese characters to transcribe the Vietnamese language can be traced to an inscription with the two characters "", as part of the posthumous title of Phùng Hưng, a national hero who succeeded in briefly expelling the Chinese in the late 8th century. The two characters have literal Chinese meanings 'cloth' and 'cover', which make no sense in this context. They have thus been interpreted as a phonetic transcription, via their Middle Chinese pronunciations ''bu^H kaj^H'', of a Vietnamese phrase, either 'great king', or 'father and mother' (of the people).

After Vietnam established its independence from China in the 10th century, Đinh Bộ Lĩnh (r. 968–979), the founder of the Đinh dynasty, named the country . The first and third Chinese characters mean 'great' and 'Viet'. The second character was often used to transcribe non-Chinese terms and names phonetically. In this context, cồ is an obsolete Vietnamese word for 'big'.

The oldest surviving inscription using Chinese characters to transcribe Vietnamese names is on a stele at the Báo Ân pagoda in Tháp Miếu village ( Phúc Yên, Vĩnh Phúc province). The inscription, re-engraved in the 18th century from an original dating from 1209, is written in Chinese but includes names of 21 people and villages written in an early form of Nom. Another stele at Hộ Thành Sơn in Ninh Bình Province (1343) is reported as listing 20 villages.

Trần Nhân Tông (r. 1278–1293) ordered that Nôm be used to communicate his proclamations to the people.
The first literary writing in Vietnamese is said to have been an incantation in verse composed in 1282 by the Minister of Justice Nguyễn Thuyên and thrown into the Red River to expel a menacing crocodile.
Four poems written in Nom from the Tran dynasty, two by Trần Nhân Tông and one each by Huyền Quang and Mạc Đĩnh Chi, were collected and published in 1805.

The Nôm text ('Sūtra explained by the Buddha on the Great Repayment of the Heavy Debt to Parents') was printed around 1730, but conspicuously avoids the character , suggesting that it was written (or copied) during the reign of Lê Lợi (1428–1433).
Based on archaic features of the text compared with the Tran dynasty poems, including an exceptional number of words with initial consonant clusters written with pairs of characters, some scholars suggest that it is a copy of an earlier original, perhaps as early as the 12th century.

Hồ dynasty (1400–07) and Ming conquest (1407–27)

During the seven years of the Hồ dynasty (1400–07) Classical Chinese was discouraged in favor of vernacular Vietnamese written in Nôm, which became the official script. The emperor Hồ Quý Ly even ordered the translation of the Book of Documents into Nôm and pushed for reinterpretation of Confucian thoughts in his book ''Minh đạo''. These efforts were reversed with the fall of the Hồ and Chinese conquest of 1407, lasting twenty years, during which use of the vernacular language and demotic script were suppressed.

During the Ming dynasty occupation of Vietnam, chữ Nôm printing blocks, texts and inscriptions were thoroughly destroyed; as a result the earliest surviving texts of chữ Nôm post-date the occupation.

15th to 19th century

Among the earlier works in Nôm of this era are the writings of Nguyễn Trãi (1380–1442).Mark W. McLeod, Thi Dieu Nguyen,
Culture and Customs of Vietnam
', Greenwood Publishing Group, 2001, p. 68. The corpus of Nôm writings grew over time as did more scholarly compilations of the script itself. , consort of King Lê Thần Tông, is generally given credit for ' (; 'guide to Southern Jade sounds: explanations and meanings'), a 24,000-character bilingual Hán-to-Nôm dictionary compiled between the 15th and 18th centuries, most likely in 1641 or 1761.Viết Luân Chu,
Thanh Hóa, thế và lực mới trong thế kỷ XXI
', 2003, p. 52

While almost all official writings and documents continued to be written in classical Chinese until the early 20th century, Nôm was the preferred script for literary compositions of the cultural elites. Nôm reached its golden period with the Nguyễn dynasty in the 19th century as it became a vehicle for diverse genres, from novels to theatrical pieces, and instructional manuals. Although it was prohibited during the reign of Minh Mạng (1820–1840), apogees of Vietnamese literature emerged with Nguyễn Du's '' The Tale of Kiều'' and Hồ Xuân Hương's poetry. Although literacy in premodern Vietnam was limited to just 3 to 5 percent of the population, nearly every village had someone who could read Nôm aloud for the benefit of other villagers. Thus these Nôm works circulated orally in the villages, making it accessible even to the illiterates.

Chữ Nôm was the dominant script in Vietnamese Catholic literature until the late 19th century. In 1838, Jean-Louis Taberd compiled a Nôm dictionary, helping with the standardization of the script.Taberd, J.L. (1838),
Dictionarium Anamitico-Latinum
''. This is a revision of a dictionary compiled by Pierre Pigneau de Behaine in 1772–1773. It was reprinted in 1884.

The reformist Catholic scholar Nguyễn Trường Tộ presented the Emperor Tự Đức with a series of unsuccessful petitions (written in classical Chinese, like all court documents) proposing reforms in several areas of government and society. His petition ( 'Eight urgent matters', 1867), includes proposals on education, including a section entitled ('Please tolerate the national voice'). He proposed to replace classical Chinese with Vietnamese written using a script based on Chinese characters that he called ( 'Han characters with national pronunciations'), though he described this as a new creation, and did not mention chữ Nôm.

French Indochina and the Latin alphabet

From the latter half of the 19th century onwards, the French colonial authorities discouraged or simply banned the use of classical Chinese, and promoted the use of the Vietnamese alphabet, which they viewed as a stepping stone toward learning French. Language reform movements in other Asian nations stimulated Vietnamese interest in the subject. Following the Russo-Japanese War of 1905, Japan was increasingly cited as a model for modernization. The Confucian education system was compared unfavourably to the Japanese system of public education. According to a polemic by writer Phan Châu Trinh, "so-called Confucian scholars" lacked knowledge of the modern world, as well as real understanding of Han literature. Their degrees showed only that they had learned how to write characters, he claimed.

The popularity of Hanoi's short-lived Tonkin Free School suggested that broad reform was possible. In 1910, the colonial school system adopted a "Franco-Vietnamese curriculum", which emphasized French and alphabetic Vietnamese. The traditional Civil Service Examination, which emphasized the command of classical Chinese, was dismantled in 1915 in Tonkin and was given for the last time at the imperial capital of Huế on January 4, 1919. The examination system, and the education system based on it, had been in effect for almost 900 years.

The decline of the Chinese script also led to the decline of chữ Nôm given that Nôm and Chinese characters are so intimately connected. After the First World War, chữ Nôm gradually died out as the Vietnamese alphabet grew more and popular. In an article published in 1935 (based on a lecture given in 1925), Georges Cordier estimated that 70% of literate persons knew the alphabet, 20% knew chữ Nôm and 10% knew Chinese characters.Cordier, Georges (1935)
''Les trois écritures utilisées en Annam: chu-nho, chu-nom et quoc-ngu (conférence faite à l'Ecole Coloniale, à Paris, le 28 mars 1925)''
Bulletin de la Société d'Enseignement Mutuel du Tonkin 15: 121.
However, estimates of the rate of literacy in the late 1930s range from 5% to 20%.
By 1953, literacy (using the alphabet) had risen to 70%.

The Gin people, descendants of 16th-century migrants from Vietnam to islands off Dongxing in southern China, now speak a form of Yue Chinese and Vietnamese, but their priests use songbooks and scriptures written in chữ Nôm in their ceremonies.

Types of texts

* () - a category of chữ Nôm texts that translates the "sounds" (word-for-word) of the original Literary Chinese text. Examples include Tam thiên tự giải âm (), etc. Often these translations attempt to match the word order as the original Literary Chinese text with no regard for Vietnamese syntax). There is significant diversity within works called ''giải âm'' (even within a single text), with some coming fairly close to the modern concept of translation, while some are closer to annotations with "word-matching" between Literary Chinese and Vietnamese, with little to no regard to the structure or syntax of Vietnamese.

Here is a line in (), a Vietnamese translation of the Three Character Classic. It features the original text on the top of the page and the Vietnamese translation on the bottom.

Characters

Vietnamese is a tonal language, as is Chinese, and has nearly 5,000 distinct syllables.
In chữ Nôm, each monosyllabic word of Vietnamese was represented by a character, either borrowed from Chinese or locally created.
The resulting system was even more difficult to use than the Chinese script.

As an analytic language, Vietnamese was a better fit for a character-based script than Japanese and Korean, with their agglutinative morphology.
Partly for this reason, there was no development of a phonetic system that could be taught to the general public, like Japanese kana syllabary or the Korean hangul alphabet, until the arrival of the Europeans.
Moreover, most Vietnamese literati viewed Chinese as the proper medium of civilized writing, and had no interest in turning Nôm into a form of writing suitable for mass communication.

Variant characters

Chữ Nôm has never been standardized. As a result, a Vietnamese word could be represented by several Nôm characters. For example, the very word ('character', 'script'), a Chinese loanword, can be written as either (Chinese character), (Vietnamese-only compound-semantic character) or (Vietnamese-only semantic-phonetic character). For another example, the word ('middle'; 'in between') can be written either as () or (). Both characters were invented for Vietnamese and have a semantic-phonetic structure, the difference being the phonetic indicator ( vs. ).

Another example of a Vietnamese word that is represented by several Nôm characters is the word for moon, ''trăng''. It can be represented by a Chinese character that is phonetically similar to trăng, (lăng), a chữ Nôm character, () which is composed of two phonetic components (ba) and (lăng) for the Middle Vietnamese ''blăng'', or a chữ Nôm character, () composed of a phonetic component (lăng) and a semantic component meaning ('moon').

Borrowed characters

Unmodified Chinese characters were used in chữ Nôm in three different ways.

* A large proportion of Vietnamese vocabulary had been borrowed from Chinese during the Tang period. Such Sino-Vietnamese vocabulary could be written with the original Chinese character for each word, for example:
** ('service', 'corvée'), from Early Middle Chinese (EMC)
** ('root', 'foundation'), from EMC
** ('head'), from EMC
* One way to represent a native Vietnamese word was to use a Chinese character for a Chinese word with a similar meaning. For example, may also represent ('capital, funds'). In this case, the word is actually an earlier Chinese loan that has become accepted as Vietnamese; William Hannas claims that all such readings are similar early loans.
* Alternatively, a native Vietnamese word could be written using a Chinese character for a Chinese word with a similar sound, regardless of the meaning of the Chinese word. For example, (Early Middle Chinese ) may represent the Vietnamese word ('one').

The first two categories are similar to the '' on'' and ''kun'' readings of Japanese kanji respectively. The third is similar to '' ateji'', in which characters are used only for their sound value, or the Man'yōgana script that became the origin of hiragana and katakana.

When a character would have two readings, a diacritic may be added to the character to indicate the "indigenous" reading. The two most common alternate reading diacritical marks are (), (a variant form of ) and (). Thus when is meant to be read as , it is written as , with a diacritic at the upper right corner.

Other alternate reading diacritical marks include () where a character is represented by a simplified variant with two points on either side of the character.

Locally invented characters

In contrast to the few hundred Japanese kokuji () and handful of Korean gukja (, ), which are mostly rarely used characters for indigenous natural phenomena, Vietnamese scribes created thousands of new characters, used throughout the language.

As in the Chinese writing system, the most common kind of invented character in Nôm is the phono-semantic compound, made by combining two characters or components, one suggesting the word's meaning and the other its approximate sound. For example,
* ( 'three') is composed of the phonetic part (Sino-Vietnamese reading: ) and the semantic part 'three'. 'Father' is also , but written as ), while 'turtle' is .
* ( 'mother') has 'woman' as semantic component and (Sino-Vietnamese reading: ) as phonetic component.

A smaller group consists of semantic compound characters, which are composed of two Chinese characters representing words of similar meaning. For example, ( or 'sky', 'heaven') is composed of ('sky') and ('upper').

A few characters were obtained by modifying Chinese characters related either semantically or phonetically to the word to be represented. For example,
* the Nôm character ( 'that', 'those') is a simplified form of the Chinese character (Sino-Vietnamese reading: ).
* the Nôm character ( 'work', 'labour') is a simplified form of the Chinese character (Sino-Vietnamese reading: ) ( > > ).
* the Nôm character (một 'one') comes from the right part of the Chinese character (Sino-Vietnamese reading: ).

Example

As an example of the way chữ Nôm was used to record Vietnamese, the first two lines of the '' Tale of Kiều'' (1871 edition), written in the traditional six-eight form of Vietnamese verse, consist of 14 characters:

Computer encoding

In 1993, the Vietnamese government released an 8-bit coding standard for alphabetic Vietnamese ( TCVN 5712:1993, or VSCII), as well as a 16-bit standard for Nôm (TCVN 5773:1993).Luong Van Phan,

The V2, V3, and V4 proposals were developed by a group at the Han-Nom Research Institute led by Nguyễn Quang Hồng. V4, developed in 2001, includes over 400 ideograms formerly used by the Tày people of northern Vietnam. This allows the Tày language to get its own registration code. V5 is a set of about 900 characters proposed in 2001. As these characters were already part of Unicode, the IRG concluded that they could not be edited and no Vietnamese code was added. (This is despite the fact that national codes were added retroactively for version 3.0 in 1999.)
