Sino-Vietnamese vocabulary in the context of "History of writing in Vietnam"

The Red River Delta or Hong River Delta (Vietnamese: Đồng bằng sông Hồng) is the flat low-lying plain formed by the Red River and its distributaries merging with the Thái Bình River in Northern Vietnam. Hồng (紅) is a Sino-Vietnamese word for "red" or "crimson". The delta has the smallest area but highest population and population density of all regions in Vietnam. The region, measuring some 15,000 square kilometres (6,000 sq mi) is well protected by a network of dikes. It is an agriculturally rich and densely populated area. Most of the land is devoted to rice cultivation.

Eight provinces, together with two municipalities (the capital Hanoi, and the port of Haiphong) form the delta. It had a population of almost 23 million in 2019.

Chữ Hán (Vietnamese: 𡨸漢 [t͡ɕɯ˦ˀ˥ haːn˧˦] , lit. 'Han characters') are the Chinese characters that were used to write Literary Chinese (Hán văn; 漢文) and Sino-Vietnamese vocabulary in Vietnamese. They were officially used in Vietnam after the Red River Delta region was incorporated into the Han dynasty and continued to be used until the early 20th century.

Chữ Nôm (𡨸喃, IPA: [t͡ɕɯ˦ˀ˥ nom˧˧]) 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), between the 15th and 19th centuries some Vietnamese literati used chữ Nôm to create 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 Nguyễn lords (Vietnamese: Chúa Nguyễn, 主阮; 1558–1777, 1780–1802), also known as the Nguyễn clan (Vietnamese: Nguyễn thị; chữ Hán: 阮氏), were Nguyễn dynasty's forerunner and a feudal noble clan ruling southern Đại Việt in the Revival Lê dynasty. The Nguyễn lords were members of the House of Nguyễn Phúc. The territory they ruled was known contemporarily as Đàng Trong (Inner Realm) and known by Europeans as the Kingdom of Cochinchina and as Kingdom of Quảng Nam (Vietnamese: Quảng Nam Quốc; chữ Hán: 廣南國) by Imperial China, in opposition to the Trịnh lords ruling northern Đại Việt as Đàng Ngoài (Outer Realm), known as the "Kingdom of Tonkin" by Europeans and "Kingdom of Annam" (Vietnamese: An Nam Quốc; chữ Hán: 安南國) by Imperial China in bilateral diplomacy. They were officially entitled, in Sino-Vietnamese, the Nguyễn Vương (chữ Hán: 阮王) in 1744 when lord Nguyễn Phúc Khoát self-proclaimed himself to elevate his status equally to Trịnh lords's title known as the Trịnh Vương (Vietnamese: Trịnh Vương; chữ Hán: 鄭王). Both Nguyễn and Trịnh clans were de jure subordinates and fief of the Lê dynasty. However, the de jure submission of the Nguyễn lords to the Trịnh lords ended in 1627 sparked the war between them.

While they recognized the authority of and claimed to be loyal subjects of the revival Lê dynasty, they were de facto rulers of southern Đại Việt. Meanwhile, the Trịnh lords ruled northern Đại Việt in the name of the Lê emperor, who was in reality a puppet ruler. They fought a series of long and bitter wars that pitted the two halves of Vietnam against each other. The Nguyễn were finally overthrown in the Tây Sơn wars, but one of their descendants would eventually come to unite all of Vietnam. Their rule consolidated earlier southward expansion into Champa and pushed southwest into Cambodia.

Hải Dương was a former province in the Red River Delta of northern Vietnam. Its name derives from Sino-Vietnamese 海陽 "ocean sun", though the modern province is in fact landlocked. Located in the Northern Key Economic Region, Hai Duong Province has a dynamic economy with a focus on industrial manufacturing.

On June 12, 2025, Hải Dương was incorporated into Haiphong.

Sino-Xenic vocabularies are large-scale and systematic borrowings of the Chinese lexicon into the Japanese, Korean and Vietnamese languages, none of which are genetically related to Chinese. The resulting Sino-Japanese, Sino-Korean and Sino-Vietnamese vocabularies now make up a large part of the lexicons of these languages. The pronunciation systems for these vocabularies originated from conscious attempts to consistently approximate the original Chinese sounds while reading Classical Chinese. They are used alongside modern varieties of Chinese in historical Chinese phonology, particularly the reconstruction of the sounds of Middle Chinese. Some other languages, such as Hmong–Mien and Kra–Dai languages, also contain large numbers of Chinese loanwords but without the systematic correspondences that characterize Sino-Xenic vocabularies.

The term was coined in 1953 by the linguist Samuel E. Martin from the Greek ξένος (xénos, 'foreign'); Martin called these borrowings "Sino-Xenic dialects".

Old Chinese, also called Archaic Chinese in older works, is the oldest attested stage of Chinese, and the ancestor of all modern varieties of Chinese. The earliest examples of Chinese are divinatory inscriptions on oracle bones from around 1250 BC, in the Late Shang period. Bronze inscriptions became plentiful during the following Zhou dynasty. The latter part of the Zhou period saw a flowering of literature, including classical works such as the Analects, the Mencius, and the Zuo Zhuan. These works served as models for Literary Chinese (or Classical Chinese), which remained the written standard until the early twentieth century, thus preserving the vocabulary and grammar of late Old Chinese.

Old Chinese was written with several early forms of Chinese characters, including oracle bone, bronze, and seal scripts. Throughout the Old Chinese period, there was a close correspondence between a character and a monosyllabic and monomorphemic word. Although the script is not alphabetic, the majority of characters were created based on phonetic considerations. At first, words that were difficult to represent visually were written using a "borrowed" character for a similar-sounding word (rebus principle). Later on, to reduce ambiguity, new characters were created for these phonetic borrowings by appending a radical that conveys a broad semantic category, resulting in compound xingsheng (phono-semantic) characters. For the earliest attested stage of Old Chinese of the late Shang dynasty, the phonetic information implicit in these xingsheng characters which are grouped into phonetic series, known as the xiesheng series, represents the only direct source of phonological data for reconstructing the language. The corpus of xingsheng characters was greatly expanded in the following Zhou dynasty. In addition, the rhymes of the earliest recorded poems, primarily those of the Classic of Poetry, provide an extensive source of phonological information with respect to syllable finals for the Central Plains dialects during the Western Zhou and Spring and Autumn periods. Similarly, the Chu Ci provides rhyme data for the dialect spoken in the Chu region during the Warring States period. These rhymes, together with clues from the phonetic components of xingsheng characters, allow most characters attested in Old Chinese to be assigned to one of 30 or 31 rhyme groups. For late Old Chinese of the Han period, the modern Southern Min languages, the oldest layer of Sino-Vietnamese vocabulary, and a few early transliterations of foreign proper names, as well as names for non-native flora and fauna, also provide insights into language reconstruction.

The Gin, Kinh or Jing people (Chinese: 京族, Sino-Vietnamese: Kinh tộc; Vietnamese: người Kinh tại Trung Quốc) are a community of descendants of ethnic Vietnamese people living in China. They mainly live in an area called the Jing Islands (京族三岛), off the coast of Dongxing, Fangchenggang, in the Chinese autonomous region of Guangxi. These territories were administered by the Nguyễn dynasty but were later ceded by the French to the Qing dynasty due to the 1887 convention, after the Sino-French war.

The Việt were labelled Yue (Chinese: 越族; pinyin: Yuèzú, Sino-Vietnamese: Việt tộc; Vietnamese: người Việt tại Trung Quốc) before the introduction of the names "Kinh", "Gin", or "Jing", in 1958. This name change was requested by the Kinh people, who did not want to be associated with the country of Vietnam, as 越/Yue made them look like Vietnamese citizens in China, and thus they chose their ethnic name, the Kinh.
