What Is Chữ Nôm and Why Did the Vietnamese Need Their Own Script?
Chữ Nôm is a writing system created by the Vietnamese to record Vietnamese, using Chinese characters as its main material and adding its own methods of formation. It is not Chinese characters read with Vietnamese pronunciation, but a script independent in function: Chinese characters record Chinese, while chữ Nôm records Vietnamese. The Vietnamese needed this script because Vietnamese has a vocabulary, grammar, and especially a syllable system different from Chinese, so Chinese characters could not be used directly to record everyday speech, folk songs, proverbs, and poetry.
Three layers of concepts are often confused. First is chữ Hán, the classical script used in examinations, administration, and scholarly literature. Second is chữ Nôm, the national script used to record Vietnamese. Third is chữ Quốc ngữ, the Latin script drafted by Western missionaries from the 17th century and becoming the official script from the early 20th century. These three scripts once coexisted, overlapped, and replaced one another in history.
Origin and Formative Milestones
Researchers generally agree that chữ Nôm began quite early, possibly around the 10th to 11th centuries, and was gradually refined through the dynasties. Commonly cited milestones include its use in steles, in the compositions of Zen masters, then in major works such as Quốc âm thi tập associated with Nguyễn Trãi, Hồng Đức quốc âm thi tập, and later Truyện Kiều by Nguyễn Du. This was a long process of accumulation, not a sudden invention by one individual.
One point to state clearly: researchers do not fully agree on the earliest date of chữ Nôm, nor on the number of chữ Nôm characters ever used. Some hold that chữ Nôm predates the 10th century; others hold that conditions for its formation only existed after independence. This article follows the presentation common in current textbooks, that chữ Nôm formed and developed over about ten centuries, tied to the Vietnamese need to record their language.
How Did the Vietnamese Borrow Chinese Characters to Write Vietnamese?
The Vietnamese borrowed Chinese characters through three main paths: borrowing the whole Chinese character to read with Vietnamese pronunciation, borrowing Chinese characters to record Vietnamese sounds, and combining Chinese characters to create new ones. These three paths correspond to three principles of formation commonly called giả tá (borrowing), hội ý (compound ideographs), and hình thanh (phono-semantic compounds). This is the core mechanism that makes chữ Nôm both similar to and different from Chinese characters.
First Principle: Borrowing the Whole Character to Read with Vietnamese Pronunciation
The simplest way is to take a Chinese character whose sound is close to the Vietnamese syllable to be recorded, then use that character to represent the Vietnamese word. For example, the Chinese character 字 originally read as "tự" was used to record the sound "chữ" in Vietnamese. This type of borrowing is called giả tá, meaning temporary borrowing. It is convenient but easily ambiguous because one Chinese character can be used for many different Vietnamese syllables depending on context.
Second Principle: Combining Meanings to Create New Characters
The second way is to combine two Chinese characters with meaning to create a chữ Nôm character representing a Vietnamese word. For example, the chữ Nôm recording the word "trời" (sky) is formed from the "thiên" (sky) component combined with the character "lại" or another element to fix the sound. This type of formation is called hội ý, meaning combining meanings. This is what gives chữ Nôm a clear ideographic character.
Third Principle: Combining a Semantic Component with a Phonetic Character
The third way, the most common and also the most refined, is to combine a part indicating meaning with a part indicating sound. For example, the chữ Nôm recording the word "ba" (the number three) can be formed from the "tam" (three) component plus a Chinese character with a sound close to "ba" to indicate pronunciation. This type of formation is called hình thanh, meaning having both form and sound. Thanks to this principle, chữ Nôm can record Vietnamese syllables that Chinese characters lack.
| Principle | Method | Illustrative Example | Advantage | Limitation |
|---|---|---|---|---|
| Giả tá | Borrow the whole Chinese character, read with Vietnamese pronunciation | Chinese character 字 read as "chữ" | Easy to write, few new characters | One character can map to many sounds, easily ambiguous |
| Hội ý | Combine two meaningful Chinese characters to create a new character | Combine the "thiên" component with another element to record "trời" | Clear meaning | Limited number of characters, hard to record purely Vietnamese sounds |
| Hình thanh | Combine a semantic component with a phonetic component | The "tam" component plus a character with a sound close to "ba" to record "ba" | Can record many Vietnamese syllables | Complex characters, large in number, hard to memorize |
Why Is Chữ Nôm Harder Than Chinese Characters?
Chữ Nôm is harder than Chinese characters in three respects. First, the number of characters is much larger, because beyond the existing Chinese character stock, the Vietnamese created additional new characters. Second, one Vietnamese word can be recorded by several different chữ Nôm characters depending on author and period, so the same sentence can have multiple spellings. Third, chữ Nôm was never thoroughly standardized like Chinese characters, so reading and transliteration require specialized knowledge. This is why chữ Nôm could not be popularized as widely as chữ Quốc ngữ later was.
What Is Special About the Nôm Version of Truyện Kiều?
Truyện Kiều by Nguyễn Du is the pinnacle of Nôm poetry and also the work that made chữ Nôm most widely known. The work was written in chữ Nôm in the lục bát (six-eight) verse form and became a cultural phenomenon lasting more than two centuries. According to information from the display space at the Memorial Site of the Great Poet Nguyễn Du in Tiên Điền commune, Hà Tĩnh province, the oldest known Truyện Kiều in chữ Nôm was published in 1866. This is an important milestone showing the work was printed and circulated widely quite early.
Why Is the Nôm Version Important?
The Nôm version is important because it is the evidence closest to the original text. When Truyện Kiều was converted to chữ Quốc ngữ and other scripts, the conversion process could lose some phonetic nuances, some archaic word usages, and some textual variants. The Nôm version helps researchers trace back the writing, reading, and understanding of contemporaries. It is also material for studying the history of Vietnamese, because chữ Nôm records the pronunciation and word usage of each period.
Truyện Kiều and Cultural Life
According to information from VietnamPlus, Truyện Kiều has been studied, interpreted, and recreated in many forms of culture and art such as Ví and Giặm folk singing, ca trù, chèo Kiều, trò Kiều, fine arts, theater, cinema, and digital media. This shows Truyện Kiều is not merely a text but a living source of inspiration. The display space in Hà Tĩnh also introduces 32 paintings of Truyện Kiều characters by famous artists, along with many related artifacts such as the Mai Hạc plate collection.
Nôm Versions and the Problem of Variants
One notable point is that Truyện Kiều exists in many variants. Different Nôm versions may differ by a few characters or lines due to manual copying or copyists' own edits. Textual scholars have devoted much effort to comparing versions and determining which is closer to the original. This is complex work requiring knowledge of chữ Nôm, printing history, and Nguyễn Du's linguistic style. This article does not go deep into debates among versions, only noting that this is a specialized field with many open points.
Why Does Chữ Nôm Still Appear on Hoành Phi and Câu Đối?
Chữ Nôm still appears on hoành phi and câu đối because these are cultural spaces of ritual, aesthetics, and community memory. A hoành phi is a horizontal plaque hung in the central bay of a đình, chùa, or family ancestral hall, usually bearing four large characters. A câu đối is two lines of Chinese or Nôm characters hung on either side of a column, symmetrical in meaning and tone. In many relics, people use chữ Nôm on hoành phi and câu đối to express national spirit, or to record teachings and praises in Vietnamese.
The Aesthetic Value of Chữ Nôm in Architecture
Chữ Nôm has a square structure with many strokes, suited to the symmetrical layout of traditional architecture. When written on wood, lacquered and gilded, chữ Nôm creates a solemn and antique feel. Many hoành phi and câu đối in chữ Nôm survive today in đình, chùa, and ancestral halls, becoming part of the architectural heritage. This is why chữ Nôm persists as a decorative and symbolic element even when it is no longer a means of daily communication.
Spiritual Value and Community Memory
In the consciousness of many Vietnamese, chữ Nôm on hoành phi and câu đối is tied to the sacredness of places of worship. It is not just writing but a reminder of ancestors, of moral principles, of values passed from generation to generation. When one can read the chữ Nôm on those plaques, one feels connected to the past. This is a form of cultural memory preserved through objects, independent of whether chữ Nôm is taught in general education.
Chữ Nôm Today: From Heritage to Contemporary Life
Chữ Nôm today is no longer a common script, but it still exists in research, heritage preservation, and creative activities by young people. According to an article in Báo Thanh Niên, the exhibition "From Vietnamese to Chữ Nôm" held in Ho Chi Minh City in August 2026 attracted many young people. The exhibition displayed 20 projects by students of the Hán Nôm Heritage class, including Đông Hồ folk paintings, a check-in area, a folk-song duel game, and creative products such as the Vân Nguyệt Tarot deck inspired by the Lục Vân Tiên narrative poem.
Why Do Young People Learn Chữ Nôm?
Young people learn chữ Nôm for many reasons. Some learn to read ancient texts for research in history, literature, and traditional medicine. Some learn to make creative products such as designs, illustrations, games, and art books. Some learn out of curiosity about cultural roots. In the article, one student shared that her group chose to combine Tarot with Lục Vân Tiên to create a product entering modern life while still carrying the heritage of ancient Nôm poetry. Another student made a project about familiar birds in the countryside to introduce the animal world to urban children.
Difficulties in Preserving Chữ Nôm
Preserving chữ Nôm faces many difficulties. First, the number of people fluent in reading and writing chữ Nôm is not large. Second, teaching chữ Nôm is not yet widespread in the general education system, mainly occurring in specialized classes, clubs, or universities. Third, many Nôm texts are deteriorating over time and need restoration and digitization. According to the article in Báo Thanh Niên, there are projects to restore Hán Nôm books carried out by individuals and small businesses, showing that the need for preservation is real and receiving community attention.
Chữ Nôm in the Context of Chữ Quốc Ngữ and Digital Technology
Chữ Quốc ngữ has become the official script, widespread and convenient for education, administration, and media. Chữ Nôm does not compete with chữ Quốc ngữ but exists as heritage. In the context of digital technology, chữ Nôm can be stored, looked up, and learned through input methods, electronic dictionaries, and databases. This is an opportunity for chữ Nôm to reach young people in new ways, without needing to print paper books or copy by hand. However, digitization also raises the issue of standardization, because chữ Nôm has many variants and no fully unified standard.
Points to Note When Studying Chữ Nôm
When studying chữ Nôm, two extremes should be avoided. One is absolutizing chữ Nôm, holding that it is the only correct script of the Vietnamese and should replace chữ Quốc ngữ. The other is dismissing chữ Nôm as an outdated script with no value. Both views are inappropriate to historical reality and the need for heritage preservation.
Another point is the need to distinguish chữ Nôm from chữ Hán in ancient texts. Many Hán Nôm texts mix both scripts depending on content and purpose. Readers need knowledge of both to understand correctly. This is why Hán Nôm Heritage classes usually teach Chinese and Nôm characters in parallel, as in the class activity at the exhibition in Ho Chi Minh City.
Finally, remember that chữ Nôm is a cultural achievement of the Vietnamese, showing creativity in adapting a foreign script to serve the mother tongue. It is not only a recording tool but also part of ethnic cultural identity. Studying chữ Nôm is a way to understand more about Vietnamese, about ancient literature, and about how earlier generations thought.
