occurred). These fricatives were not present in Proto-Viet–Muong, as indicated by their absence in Mường, but were evidently present in the later Proto-Vietnamese stage. Subsequent loss of the minor-syllable prefixes phonemicized the fricatives. Ferlus 1992 proposes that originally there were both voiced and voiceless fricatives, corresponding to original voiced or voiceless stops, but Ferlus 2009 appears to have abandoned that hypothesis, suggesting that stops were softened and voiced at approximately the same time, according to the following pattern: * > * > * > * > * > In

Origin of tones

Proto-Viet–Muong had no tones to speak of. The tones later developed in some of the daughter languages from distinctions in the initial and final consonants. Vietnamese tones developed as follows: : Glottal-ending syllables ended with a glottal stop , while fricative-ending syllables ended with or . Both types of syllables could co-occur with a resonant (e.g. or ). At some point, a

.) Subsequent to this, the plain-voiced stops became voiceless and the allotones became new phonemic tones.

, becoming a voiced fricative. The minor syllables were eventually lost, but not until the tone split had occurred. As a result, words in modern Vietnamese with voiced fricatives occur in all six tones, and the tonal register reflects the voicing of the minor-syllable prefix and not the voicing of the main-syllable stop in Proto-Viet–Muong that produced the fricative. For similar reasons, words beginning with and occur in both registers. (Thompson 1976 reconstructed voiceless resonants to account for outcomes where resonants occur with a first-register tone, but this is no longer considered necessary, at least by Ferlus.)

' glossary by Chinese diplomat Chen Fu (c. 1259 – 1309). Old Vietnamese used Chinese characters phonetically where each word, monosyllabic in Modern Vietnamese, is written with two Chinese characters or in a composite character made of two different characters. It conveys the transformation of Vietnamese lexicons from sesquisyllabic to fully monosyllabic through monosyllabization process under pressures of Chinese linguistic influence, characterized by phenomena such as the reduction of minor syllables; loss of affixal morphology drifting towards analytical grammar; simplification of major syllable segments, and change of suprasegment instruments. For examples, the modern Vietnamese word "trời" (heaven) was read as ''*plời'' in Old/Ancient Vietnamese and as ''blời'' in Middle Vietnamese.

''. It reflects the pronunciation of the Vietnamese of Hanoi at that time, a stage commonly termed ''Middle Vietnamese'' (). The pronunciation of the "rime" of the syllable, i.e. all parts other than the initial consonant (optional glide, vowel nucleus, tone and final consonant), appears nearly identical between Middle Vietnamese and modern Hanoi pronunciation. On the other hand, the Middle Vietnamese pronunciation of the initial consonant differs greatly from all modern dialects, and in fact is significantly closer to the modern Saigon dialect than the modern Hanoi dialect. The following diagram shows the orthography and pronunciation of Middle Vietnamese: : occurs only at the end of a syllable.

, Vietnamese has been recognized as one of 14 minority languages, on the basis of communities that have resided in the country either traditionally or on a long-term basis. This status grants the Vietnamese community in the country a representative on the Government Council for Nationalities, an advisory body of the Czech Government for matters of policy towards national minorities and their members. It also grants the community the right to use Vietnamese with public authorities and in courts anywhere in the country.


As a foreign language

Vietnamese is increasingly being taught in schools and institutions outside of Vietnam, a large part which is contributed by its large diaspora. In countries with strongly established Vietnamese-speaking communities such as the United States, France, Australia, Canada, Germany, and the Czech Republic, Vietnamese language education largely serves as a cultural role to link descendants of Vietnamese immigrants to their ancestral culture. Meanwhile, in countries near Vietnam such as Cambodia, Laos, and Thailand, the increased role of Vietnamese in foreign language education is largely due to the recent recovery of the Vietnamese economy. Since the 1980s, Vietnamese language schools () have been established for youth in many Vietnamese-speaking communities around the world, notably in the United States. Similarly, since the late 1980s, the Vietnamese-German community has enlisted the support of city governments to bring Vietnamese into high school curriculum for the purpose of teaching and reminding Vietnamese German students of their mother-tongue. Furthermore, there has also been a number of Germans studying Vietnamese due to increased economic investments and business.Vietnamese teaching and learning overwhelming Germany

Historic and stronger trade and diplomatic relations with Vietnam and a growing interest among the French Vietnamese population (one of France's most established non-European ethnic groups) of their ancestral culture have also led to an increasing number of institutions in France, including universities, to offer formal courses in the language.


Phonology


Vowels

, whereas the back vowels (u, ô, o) are rounded. The vowels â and ă are pronounced very short, much shorter than the other vowels. Thus, ơ and â are basically pronounced the same except that ơ is of normal length while â is short – the same applies to the vowels long a and short ă .There are different descriptions of Hanoi vowels. Another common description is that of : : This description distinguishes four degrees of vowel height and a rounding contrast (rounded vs. unrounded) between back vowels. The relative shortness of ''ă'' and ''â'' would then be a secondary feature. Thompson describes the vowel ''ă'' as being slightly higher ( upper low) than ''a'' . The centering diphthongs are formed with only the three high vowels (i, ư, u). They are generally spelled as ia, ưa, ua when they end a word and are spelled iê, ươ, uô, respectively, when they are followed by a consonant. In addition to single vowels (or

s. The closing diphthongs and triphthongs consist of a main vowel component followed by a shorter semivowel offglide or .The closing diphthongs and triphthongs as described by Thompson can be compared with the description above: : There are restrictions on the high offglides: cannot occur after a front vowel (i, ê, e) nucleus and cannot occur after a back vowel (u, ô, o) nucleus. : The correspondence between the orthography and pronunciation is complicated. For example, the offglide is usually written as ''i''; however, it may also be represented with ''y''. In addition, in the diphthongs and the letters ''y'' and ''i'' also indicate the pronunciation of the main vowel: ay = ă + , ai = a + . Thus, ''tay'' "hand" is while ''tai'' "ear" is . Similarly, u and o indicate different pronunciations of the main vowel: au = ă + , ao = a + . Thus, ''thau'' "brass" is while ''thao'' "raw silk" is .


Consonants

The consonants that occur in Vietnamese are listed below in the Vietnamese orthography with the phonetic pronunciation to the right. : Some consonant sounds are written with only one letter (like "p"), other consonant sounds are written with a digraph (like "ph"), and others are written with more than one letter or digraph (the velar stop is written variously as "c", "k", or "q"). Not all dialects of Vietnamese have the same consonant in a given word (although all dialects use the same spelling in the written language). See the language variation section for further elaboration. Syllable-final orthographic ''ch'' and ''nh'' in Vietnamese has had different analyses. One analysis has final ''ch'', ''nh'' as being phonemes contrasting with syllable-final ''t'', ''c'' and ''n'', ''ng'' and identifies final ''ch'' with the syllable-initial ''ch'' . The other analysis has final ''ch'' and ''nh'' as predictable
allophonic In phonology, an allophone (; from the Greek , , 'other' and , , 'voice, sound') is a set of multiple possible spoken soundsor ''phones''or signs used to pronounce a single phoneme in a particular language. For example, in English, (as in ''s ...
variants of the velar phonemes and that occur after the upper front vowels ''i'' and ''ê'' ; although they also occur after ''a'', but in such cases are believed to have resulted from an earlier ''e'' which diphthongized to ''ai'' (cf. ''ach'' from ''aic'', ''anh'' from ''aing''). (See Vietnamese phonology: Analysis of final ''ch'', ''nh'' for further details.)


Tones

Each Vietnamese syllable is pronounced with one of six inherent tones, centered on the main vowel or group of vowels. Tones differ in: * length (duration) *
pitch contour __NOTOC__ In linguistics, speech synthesis, and music, the pitch contour of a sound is a function or curve that tracks the perceived pitch of the sound over time. Pitch contour may include multiple sounds utilizing many pitches, and can relate t ...

Tone is indicated by diacritics written above or below the vowel (most of the tone diacritics appear above the vowel; however, the ''nặng'' tone dot diacritic goes below the vowel). The six tones in the northern varieties (including Hanoi), with their self-referential Vietnamese names, are: Other dialects of Vietnamese may have fewer tones (typically only five). In Vietnamese poetry, tones are classed into two groups: (

Japanese

Japanese loanwords are a more recently studied phenomenon, with a paper by Nguyễn & Lê (2020) classifying three layers of Japanese loanwords, where the third layer was used by Vietnamese who studied Japanese and the first two layers being the main layers of borrowings that were derived from Japanese. The first layer consisted of Kanji words created by Japanese to represent Western concepts that were not readily available in Chinese or Japanese, where by the end of the 19th century they were imported to other Asian languages. This first layer was called Sino-Vietnamese words of Japanese-origins. For example, the Vietnamese term for "association club", ''câu lạc bộ,'' which was borrowed from Chinese (;

However, Japanese cultural influence in Vietnam started significantly from the 1980s. This new, second layer of Japan-origin loanwords is distinctive from Sino-Vietnamese words of Japanese-origin in that they were borrowed directly from Japanese. This vocabulary included words representative of Japanese culture, such as ''kimono'', ''sumo'', ''samurai'', and ''bonsai'' from modified Hepburn romanisation. These loanwords are coined as "new Japanese loanwords". A significant number of new Japanese loanwords were also of Chinese origin. Sometimes, the same concept can be described using both Sino-Vietnamese words of Japanese origin (first layer) and new Japanese loanwords (second layer). For example, judo can be referred to as both ''judo'' and ''nhu đạo'', the Vietnamese reading of 柔道.

Pure Vietnamese words

Basic vocabulary in Vietnamese are of Proto-Vietic origins, these words are considered as pure Vietnamese words rather than loanwords. Vietnamese shares a large amount of vocabulary with the Mường languages, a close relative of the Vietnamese language. Other compound words, like nước non (chữ Nôm: 渃𡽫) meaning figuratively ''country; nation'' (literally meaning, water and mountains) seem to be purely Vietnamese inventions, which used to be inscribed in chữ Nôm characters, which were compounded self-coined Chinese characters, which are now written in the Vietnamese alphabet.

Dates and numbers writing formats

Vietnamese speak date in the format "day month year". Each month's name is just the ordinal of that month appended after the word ''tháng'', which means "month". Traditional Vietnamese however assigns other names to some months; these names are mostly used in the lunar calendar and in poetry. When written in the short form, "DD/MM/YYYY" is preferred. ''Example:'' *English: 28 March 2018 *Vietnamese long form: Ngày 28 tháng 3 năm 2018 *Vietnamese short form: 28/3/2018 The Vietnamese prefer writing numbers with a comma as the decimal separator in lieu of dots, and either spaces or dots to group the digits. An example is 1 629,15 (one thousand six hundred twenty-nine point fifteen). Because a comma is used as the decimal separator, a semicolon is used to separate two numbers instead.

Language variation

The Vietnamese language has several mutual intelligibility, mutually intelligible regional varieties: Vietnamese has traditionally been divided into three dialect regions: North, Central, and South. Michel Ferlus and Nguyễn Tài Cẩn found that there was a separate North-Central dialect for Vietnamese as well. The term ''Haut-Annam'' refers to dialects spoken from the northern Nghệ An Province to the southern (former) Thừa Thiên Province that preserve archaic features (like consonant clusters and undiphthongized vowels) that have been lost in other modern dialects. The dialect regions differ mostly in their sound systems (see below) but also in vocabulary (including basic vocabulary, non-basic vocabulary, and grammatical words) and grammar. The North-Central and the Central regional varieties, which have a significant number of vocabulary differences, are generally less mutually intelligible to Northern and Southern speakers. There is less internal variation within the Southern region than the other regions because of its relatively late settlement by Vietnamese-speakers (around the end of the 15th century). The North-Central region is particularly conservative since its pronunciation has diverged less from Vietnamese orthography than the other varieties, which tend to merge certain sounds. Along the coastal areas, regional variation has been neutralized to a certain extent, but more mountainous regions preserve more variation. As for sociolinguistic attitudes, the North-Central varieties are often felt to be "peculiar" or "difficult to understand" by speakers of other dialects although their pronunciation fits the written language the most closely; that is typically because of various words in their vocabulary thar are unfamiliar to other speakers (see the example vocabulary table below). The large movements of people between North and South since the mid-20th century has resulted in a sizable number of Southern residents speaking in the Northern accent/dialect and, to a greater extent, Northern residents speaking in the Southern accent/dialect. After the Geneva Conference (1954), Geneva Accords of 1954, which called for the Geneva Conference (1954), temporary division of the country, about a million northerners (mainly from Hanoi, Haiphong, and the surrounding Red River Delta areas) moved south (mainly to Saigon and heavily to Biên Hòa and Vũng Tàu and the surrounding areas) as part of Operation Passage to Freedom. About 180,000 moved in the reverse direction (''Tập kết ra Bắc'', literally "go to the North".) After the Fall of Saigon in 1975, Northern and North-Central speakers from the densely-populated Red River Delta and the traditionally-poorer provinces of Nghệ An, Hà Tĩnh, and Quảng Bình have continued to move south to look for better economic opportunities since the new government's New Economic Zones, a program that lasted from 1975 to 1985. The first half of the program (1975–1980) resulted in 1.3 million people sent to the New Economic Zones (NEZs), most of which were relocated to the southern half of the country in previously-uninhabited areas, and 550,000 of them were Northerners. The second half (1981–1985) saw almost 1 million Northerners relocated to the New Economic Zones. Government and military personnel from Northern and North-Central Vietnam are also posted to various locations throughout the country that were often away from their home regions. More recently, the growth of the free market system has resulted in increased interregional movement and relations between distant parts of Vietnam through business and travel. The movements have also resulted in some blending of dialects and more significantly have made the Northern dialect more easily understood in the South and vice versa. Most Southerners, when singing modern/old popular Vietnamese songs or addressing the public, do so in the standardized accent if possible, which uses the Northern pronunciation. That is true in both Vietnam and overseas Vietnamese communities. Modern Standard Vietnamese is based on the Hanoi dialect. Nevertheless, the major dialects are still predominant in their respective areas and have also evolved over time with influences from other areas. Historically, accents have been distinguished by how each region pronounces the letters ''d'' ([z] in the Northern dialect and [j] in the Central and Southern dialect) and ''r'' ([z] in the Northern dialect and [r] in the Central and Southern dialects). Thus, the Central and the Southern dialects can be said to have retained a pronunciation closer to Vietnamese orthography and resemble how Middle Vietnamese sounded, in contrast to the modern Northern (Hanoi) dialect, which has since undergone pronunciation shifts.


Vocabulary

Although regional variations developed over time, most of those words can be used interchangeably and be understood well, albeit with more or less frequency then others or with slightly different but often discernible word choices and pronunciations. Some accents may mix, with words such ''dạ vâng'' combining ''dạ'' and ''vâng,'' being created''.''


Consonants

The syllable-initial ''ch'' and ''tr'' digraphs are pronounced distinctly in the North-Central, Central, and Southern varieties but are merged in Northern varieties, which pronounce them the same way). Many North-Central varieties preserve three distinct pronunciations for ''d'', ''gi'', and ''r'', but the Northern varieties have a three-way merger, and the Central and the Southern varieties have a merger of ''d'' and ''gi'' but keep ''r'' distinct. At the end of syllables, the palatals ''ch'' and ''nh'' have merged with the alveolars ''t'' and ''n'', which, in turn, have also partially merged with velars ''c'' and ''ng'' in the Central and the Southern varieties. In addition to the regional variation described above, there is a merger of ''l'' and ''n'' in certain rural varieties in the North: Variation between ''l'' and ''n'' can be found even in mainstream Vietnamese in certain words. For example, the numeral "five" appears as ''năm'' by itself and in compound numerals like ''năm mươi'' "fifty," but it appears as in "fifteen" (see Vietnamese grammar#Cardinal). In some northern varieties, the numeral appears with an initial ''nh'' instead of ''l'': "twenty-five", instead of the mainstream . There is also a merger of ''r'' and ''g'' in certain rural varieties in the South: The consonant clusters that were originally present in Middle Vietnamese (in the 17th century) have been lost in almost all modern Vietnamese varieties although they have been retained in other closely-related Vietic languages. However, some speech communities have preserved some of these archaic clusters: "sky" is with a cluster in Hảo Nho (Yên Mô District, Yên Mô, Ninh Bình Province) but ''trời'' in Southern Vietnamese and in Hanoi Vietnamese (initial single consonants , respectively).


Tones

Although there are six tones in Vietnamese, some tones may slightly merge but are still highly distinguishable from the context of the speech. The ''hỏi'' and ''ngã'' tones are distinct in North and some North-Central varieties (although often with different
pitch contour __NOTOC__ In linguistics, speech synthesis, and music, the pitch contour of a sound is a function or curve that tracks the perceived pitch of the sound over time. Pitch contour may include multiple sounds utilizing many pitches, and can relate t ...
s) but have somewhat merged in the Central, Southern, and some North-Central varieties (also with different pitch contours). Some North-Central varieties (such as Vietnamese) have a slight merger of the ''ngã'' and ''nặng'' tones but keep the ''hỏi'' tone distinct. Still, other North-Central varieties have a three-way merger of ''hỏi'', ''ngã'', and ''nặng'' and so have a four-tone system. In addition, there are several phonetic differences (mostly in pitch contour and

type) in the tones among the dialects. The table above shows the pitch contour of each tone using Tone (linguistics)#Asia, Chao tone number notation in which 1 represents the lowest pitch, and 5 the highest; glottalization (creaky voice, creaky, stiff voice, stiff, harsh voice, harsh) is indicated with the symbol; murmured voice with ; glottal stop with ; sub-dialectal variants are separated with commas. (See also the #Tones, tone section below.)


Word play

A basic form of word play in Vietnamese involves disyllabic words in which the last syllable forms the first syllable of the next word in the chain. This game involves two members versing each other until the opponent is unable to think of another word. For instance: Another language game known as ''nói lái'' is used by Vietnamese speakers. ''Nói lái'' involves switching, adding or removing the tones in a pair of words and may also involve switching the order of words or the first consonant and the Syllable rime, rime of each word. Some examples: : The resulting transformed phrase often has a different meaning but sometimes may just be a nonsensical word pair. ''Nói lái'' can be used to obscure the original meaning and thus soften the discussion of a socially sensitive issue, as with ''dấm đài'' and ''hoảng chưa'' (above), or when implied (and not overtly spoken), to deliver a hidden subtextual message, as with ''bồi tây''. Naturally, ''nói lái'' can be used for a humorous effect.www.users.bigpond.com/doanviettrung/noilai.html

for more examples.
Another word game somewhat reminiscent of pig latin is played by children. Here a nonsense syllable (chosen by the child) is prefixed onto a target word's syllables, then their initial consonants and rimes are switched with the tone of the original word remaining on the new switched rime. : This language game is often used as a "secret" or "coded" language useful for obscuring messages from adult comprehension.
