Official language in
Natively Vietnamese-speaking (non-minority) areas of Vietnam and China
Vietnamese i// (tiếng Việt) is the national, official language of Vietnam. It is the native language of Vietnamese people (Kinh), and of about three million Vietnamese residing elsewhere. It also is spoken as a first or second language by many ethnic minorities of Vietnam.
It is part of the Austroasiatic language family of which it has, by far, the most speakers (several times that of the other Austroasiatic languages combined). Vietnamese vocabulary has borrowings from Chinese, and it formerly used a modified set of Chinese characters called chữ nôm given vernacular pronunciation. The Vietnamese alphabet (quốc ngữ) in use today is a Latin alphabet with additional diacritics for tones, and certain letters.

As the national language, Vietnamese is spoken throughout Vietnam by ethnic Vietnamese and by Vietnam's many minorities. A few thousand native speakers live just across the border in China. It also is spoken in overseas Vietnamese communities, most notably in the United States, where it has more than one million speakers and is the sixth most-spoken language (it is third in Texas, fourth in Arkansas and Louisiana, and fifth in California). It is the seventh most-spoken language in Australia. In France, Vietnamese is the most spoken Asian language and the eighth most spoken immigrant language.
Vietnamese was identified more than 150 years ago as part of the Mon–Khmer branch of the Austroasiatic language family (a family that also includes Khmer, spoken in Cambodia, as well as various tribal and regional languages, such as the Munda and Khasi languages spoken in eastern India, and others in southern China). Later, Mường was found to be more closely related to Vietnamese than other Mon–Khmer languages, and a Việt-Mường sub-grouping was established, also including Thavưng, Chứt, Hung, etc. The term Vietic was proposed by Hayes (1992), who proposed to redefine Việt–Mường as referring to a sub-branch of Vietic containing only Vietnamese and Mường. The term Vietic is used, among others, by Gérard Diffloth, with a slightly different proposal on subclassification, within which the term Việt-Mường refers to a lower sub-grouping (within an eastern Vietic branch) consisting of Vietnamese dialects, Mường dialects, and Nguồn (of Quảng Bình Province).
As a result of 1000 years of Chinese rule, much of the Vietnamese lexicon relating to science and politics is derived from Chinese — see Sino-Vietnamese vocabulary. Some 30% to 60% of the lexical stock has naturalized word borrowings from China, although many compound words are composed of native Vietnamese words combined with naturalized word borrowings (i.e., having Vietnamese pronunciation) . As a result of French occupation, Vietnamese has since had many words borrowed from the French language, for example cà phê (from French café). Nowadays, many new words are being added to the language's lexicon due to heavy Western cultural influence; these are usually borrowed from English, for example TV (though usually seen in the written form as tivi). Sometimes these borrowings are calques literally translated into Vietnamese (for example, software is calqued into phần mềm, which literally means "soft part").
Front Central Back Close i [i] ư [ɨ] u [u] Close-mid ê [e] ơ [əː] ô [o] Open-mid e [ɛ] â [ə] o [ɔ] Open ă [a] / a [aː]
Front, central, and low vowels (i, ê, e, ư, â, ơ, ă, a) are unrounded, whereas the back vowels (u, ô, o) are rounded. The vowels â [ə] and ă [a] are pronounced very short, much shorter than the other vowels. Thus, ơ and â are basically pronounced the same except that ơ [əː] is of normal length while â [ə] is short – the same applies to the vowels long a [aː] and short ă [a].
In addition to single vowels (or monophthongs), Vietnamese has diphthongs and triphthongs. The diphthongs consist of a main vowel component followed by a shorter semivowel offglide to a high front position [ɪ̯], a high back position [ʊ̯], or a central position [ə̯].
Vowel nucleus Diphthong with front offglide Diphthong with back offglide Diphthong with centering offglide Triphthong with front offglide Triphthong with back offglide i – iu [iʊ̯] ia~iê~yê [iə̯] – iêu [iə̯ʊ̯] ê – êu [eʊ̯] – – – e – eo [ɛʊ̯] – – – ư ưi [ɨɪ̯] ưu [ɨʊ̯] ưa~ươ [ɨə̯] ươi [ɨə̯ɪ̯] ươu [ɨə̯ʊ̯] â ây [əɪ̯] âu [əʊ̯] – – – ơ ơi [əːɪ̯] – – – – ă ay [aɪ̯] au [aʊ̯] – – – a ai [aːɪ̯] ao [aːʊ̯] – – – u ui [uɪ̯] – ua~uô [uə̯] uôi [uə̯ɪ̯] – ô ôi [oɪ̯] – – – – o oi [ɔɪ̯] – – – –
The centering diphthongs are formed with only the three high vowels (i, ư, u) as the main vowel. 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. There are also restrictions on the high offglides: the high front offglide cannot occur after a front vowel (i, ê, e) nucleus and the high back offglide cannot occur after a back vowel (u, ô, o) nucleus.
The correspondence between the orthography and pronunciation is complicated. For example, the offglide [ɪ̯] is usually written as i; however, it may also be represented with y. In addition, in the diphthongs [aɪ̯] and [aːɪ̯] the letters y and i also indicate the pronunciation of the main vowel: ay = ă + [ɪ̯], ai = a + [ɪ̯]. Thus, tay "hand" is [taɪ̯] while tai "ear" is [taːɪ̯]. Similarly, u and o indicate different pronunciations of the main vowel: au = ă + [ʊ̯], ao = a + [ʊ̯]. Thus, thau "brass" is [tʰaʊ̯] while thao "raw silk" is [tʰaːʊ̯].
The four triphthongs are formed by adding front and back offglides to the centering diphthongs. Similarly to the restrictions involving diphthongs, a triphthong with front nucleus cannot have a front offglide (after the centering glide) and a triphthong with a back nucleus cannot have a back offglide.
From the front and back offglides [ɪ̯], [ʊ̯], many phonological descriptions analyze these as consonant glides /j/, /w/. Thus, a word such as đâu "where", phonetically [ɗəʊ̯], would be analyzed phonemically as /ɗəw/.
The consonants that occur in Vietnamese are listed below in the Vietnamese orthography with the phonetic pronunciation to the right.
Labial Alveolar Retroflex Palatal Velar Glottal Nasal m [m] n [n] nh [ɲ] ng/ngh [ŋ] Stop voiceless p [p] t [t] tr [ʈʂ~ʈ] ch [c~tɕ] c/k/q [k] voiced b [ɓ] đ [ɗ] aspirated th [tʰ] kh [x~kʰ] Fricative voiceless ph [f] x [s] s [ʂ] h [h] voiced v [v] d [z~j] r [ʐ~ɹ] gi [z~j] g/gh [ɣ] Approximant u/o [w] l [l] y/i [j]
Some consonant sounds are written with only one letter (like "p"), other consonant sounds are written with a two-letter 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.
The analysis of syllable-final orthographic ch and nh in Hanoi Vietnamese has had different analyses. One analysis has final ch, nh as being phonemes /c/, /ɲ/ contrasting with syllable-final t, c /t/, /k/ and n, ng /n/, /ŋ/ and identifies final ch with the syllable-initial ch /c/. The other analysis has final ch and nh as predictable allophonic variants of the velar phonemes /k/ and /ŋ/ that occur before upper front vowels i /i/ and ê /e/. (See Vietnamese phonology: Analysis of final ch, nh for further details.)
Vietnamese vowels are all pronounced with an inherent tone. (More formally, diacritics indicate the tone of the entire word, centered on the main vowel or group of vowels, whereas accents qualify the vowel(s).) Tones differ in:
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:
|ngang 'level'||mid level||(no mark)||ma 'ghost'||a (help·info)|
|huyền 'hanging'||low falling (often breathy)||` (grave accent)||mà 'but'||à (help·info)|
|sắc 'sharp'||high rising||´ (acute accent)||má 'cheek, mother (southern)'||á (help·info)|
|hỏi 'asking'||mid dipping-rising||̉ (hook)||mả 'tomb, grave'||ả (help·info)|
|ngã 'tumbling'||high breaking-rising||˜ (tilde)||mã 'horse (Sino-Vietnamese), code'||ã (help·info)|
|nặng 'heavy'||low falling constricted (short length)||̣ (dot below)||mạ 'rice seedling'||ạ (help·info)|
Other dialects of Vietnamese have fewer tones (typically only five). See the language variation section for a brief survey of tonal differences among dialects.
In Vietnamese poetry, tones are classed into two groups:
|Tone group||Tones within tone group|
|bằng "level, flat"||ngang and huyền|
|trắc "oblique, sharp"||sắc, hỏi, ngã, and nặng|
Words with tones belonging to a particular tone group must occur in certain positions with the poetic verse.

Vietnamese has traditionally been divided into three dialect regions: North, Central, and South. However, Michel Ferlus and Nguyễn Tài Cẩn offer evidence for considering a North-Central region separate from Central. The term Haut-Annam refers to dialects spoken from northern Nghệ An Province to southern (former) Thừa Thiên Province that preserve archaic features (like consonant clusters and undiphthongized vowels) that have been lost in other modern dialects.
These 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 Central regional varieties, which have a significant amount 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 due to its relatively late settlement by Vietnamese speakers (in around the end of the 15th century). The North-central region is particularly conservative. Along the coastal areas, regional variation has been neutralized to a certain extent, while 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.
The large movements of people between North and South beginning in the mid-20th century and continuing to this day have resulted in a sizeable number of Southern residents speaking in the Northern accent/dialect and, to a greater extent, Northern residents speaking in the Southern accent/dialect. Following the Geneva Accords of 1954 that called for the 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 3% (~30,000) of that number of people made the move in the reverse direction.
Following the reunification of Vietnam in 1975–76, 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, beginning with the Hanoi government's "New Economic Zones program" which lasted from 1975–85. The first half of the program (1975–80), resulted in 1.3 million people sent to the New Economic Zones (NEZs), majority of which were relocated in the southern half of the country in previously uninhabited areas, of which 550,000 were Northerners. The second half (1981–85) saw almost 1 million Northerners relocated to the NEZs. As well, government and military personnel, many from Northern and north-central Vietnam, are posted to various locations throughout the country, often away from their home regions. More recently, the growth of the free market system has resulted in business people and tourists traveling to distant parts of Vietnam. These movements have resulted in some small blending of the dialects, but more significantly, have made the Northern dialect more easily understood in the South and vice versa. Most Southerners, when singing modern/popular Vietnamese songs, do so in the Northern accent. This is true in Vietnam as well as in the overseas Vietnamese communities.

The syllable-initial ch and tr digraphs are pronounced distinctly in North-central, Central, and Southern varieties, but are merged in Northern varieties (i.e. they are both pronounced the same way). The North-central varieties preserve three distinct pronunciations for d, gi, and r whereas the North has a three-way merger and the Central and South have a merger of d and gi while keeping r distinct. At the end of syllables, palatals ch and nh have merged with alveolars t and n, which, in turn, have also partially merged with velars c and ng in Central and Southern varieties.

In addition to the regional variation described above, there is also a merger of l and n in certain rural varieties:
l, n variation Orthography "Mainstream" varieties Rural varieties n [n] [n] l [l]
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 appears as lăm in mười lăm "fifteen". (See Vietnamese syntax: Cardinal numerals.) In some northern varieties, this numeral appears with an initial nh instead of l: hai mươi nhăm "twenty-five" vs. mainstream hai mươi lăm.
The consonant clusters that were originally present in Middle Vietnamese (of the 17th century) have been lost in almost all modern Vietnamese varieties (but retained in other closely related Vietic languages). However, some speech communities have preserved some of these archaic clusters: "sky" is blời with a cluster in Hảo Nho (Yên Mô prefecture, Ninh Bình Province) but trời in Southern Vietnamese and giời in Hanoi Vietnamese (initial single consonants /ʈᶳ/, /z/, respectively).
Generally, the Northern varieties have six tones while those in other regions have five tones. The hỏi and ngã tones are distinct in North and some North-central varieties (although often with different pitch contours) but have merged in Central, Southern, and some North-central varieties (also with different pitch contours). Some North-central varieties (such as Hà Tĩnh Vietnamese) have a merger of the ngã and nặng tones while keeping the hỏi tone distinct. Still other North-central varieties have a three-way merger of hỏi, ngã, and nặng resulting in a four-tone system. In addition, there are several phonetic differences (mostly in pitch contour and phonation type) in the tones among dialects.

Vietnamese, like many languages in Southeast Asia, is an analytic (or isolating) language. Vietnamese does not use morphological marking of case, gender, number or tense (and, as a result, has no finite/nonfinite distinction). Also like other languages in the region, Vietnamese syntax conforms to subject–verb–object word order, is head-initial (displaying modified-modifier ordering), and has a noun classifier system. Additionally, it is pro-drop, wh-in-situ, and allows verb serialization.

Up to the late 19th century, two writing systems based on Chinese characters were used in Vietnam. All formal writing, including government business, scholarship and formal literature, was done in Literary Chinese (chữ nho 𡨸儒 "scholar's characters"). Folk literature in Vietnamese was recorded using the Chữ Nôm script, in which many Chinese characters were borrowed and many more modified and invented to represent native Vietnamese words. Created in the 13th century or earlier, the Nôm writing reached its zenith in the 18th century when many Vietnamese writers and poets composed their works in Nôm, most notably Nguyễn Du and Hồ Xuân Hương (dubbed "the Queen of Nôm poetry"). However it was only used for official purposes during the brief Hồ and Tây Sơn dynasties.
A Vietnamese Catholic, Nguyen Truong To, sent petitions to the Court which suggested a Chinese character-based syllabary which would be used for Vietnamese sounds; however, his petition failed. The French colonial administration sought to eliminate the Chinese writing system, Confucianism, and other Chinese influences from Vietnam by getting rid of Nôm.
A romanization of Vietnamese was codified in the 17th century by the French Jesuit missionary Alexandre de Rhodes (1591–1660), based on works of earlier Portuguese missionaries Gaspar do Amaral and António Barbosa. This Vietnamese alphabet (quốc ngữ or "national script", literally "national language") was gradually expanded from its initial domain in Christian writing to become more popular among the general public. However, the Romanized script did not come to predominate until the beginning of the 20th century, when education became widespread and a simpler writing system was found more expedient for teaching and communication with the general population. Under French colonial rule, French superseded Chinese in administration. Vietnamese written with the alphabet became required for all public documents in 1910 by issue of a decree by the French Résident Supérieur of the protectorate of Tonkin. By the middle of the 20th century virtually all writing was done in quốc ngữ, which became the official script on independence. Chữ nho was still in use on early North Vietnamese and late French Indochinese banknotes issued after World War II but fell out of official use shortly thereafter. Only a few scholars and some extremely elderly people are able to read chữ nôm today. In China, members of the Jing minority still write in Chữ Nôm.
Changes in the script were made by French scholars and administrators and by conferences held after independence during 1954–1974. The script now reflects a so-called Middle Vietnamese dialect that has vowels and final consonants most similar to northern dialects and initial consonants most similar to southern dialects (Nguyễn 1996). This Middle Vietnamese is presumably close to the Hanoi variety as spoken sometime after 1600 but before the present. (This is not unlike how English orthography is based on the Chancery Standard of late Middle English, with many spellings retained even after significant phonetic change.)
The Unicode character set contains all Vietnamese characters and the Vietnamese currency symbol. On systems that do not support Unicode, many 8-bit Vietnamese code pages are available such as VISCII or CP1258. Where ASCII must be used, Vietnamese letters are often typed using the VIQR convention, though this is largely unnecessary with the increasing ubiquity of Unicode. There are many software tools that help type true Vietnamese text on US keyboards, such as WinVNKey and Unikey on Windows, or MacVNKey on Macintosh.
It seems likely that in the distant past, Vietnamese shared more characteristics common to other languages in the Austroasiatic family, such as an inflectional morphology and a richer set of consonant clusters, which have subsequently disappeared from the language. However, Vietnamese appears to have been heavily influenced by its location in the Southeast Asian sprachbund, with the result that it has acquired or converged toward characteristics such as isolating morphology and phonemically distinctive tones, through processes of tonogenesis. These characteristics have become part of many of the genetically unrelated languages of Southeast Asia; for example, Thai (one of the Tai–Kadai languages), Tsat (a member of the Malayo-Polynesian group within Austronesian), and Vietnamese each developed tones as a phonemic feature.
The ancestor of the Vietnamese language is usually believed to have been originally based in the area of the Red River in what is now northern Vietnam. However, Chamberlain argues that the Red River Delta region was originally Tai-speaking and became Vietnamese-speaking only between the seventh and ninth centuries AD, as a result of immigration from the south, i. e., modern central Vietnam, where the highly distinctive and conservative North-Central Vietnamese dialects are spoken today. Therefore, the region of origin of Vietnamese (and the earlier Viet–Muong) was well south of the Red River.
Like the ethnonym Lao, the name Yue/Việt originally referred to Tai–Kadai-speaking groups. In northern Vietnam, these later adopted Viet–Muong and further north Chinese varieties, where the designation Yue Chinese preserves the ethnonym. (Both in Vietnam and southern China, however, many Tai–Kadai languages remain in use.) This explains the fact that the same ethnonym Yue ~ Việt is associated with groups that speak Tai–Kadai, Austroasiatic and Chinese languages, which are typologically similar and share significant amounts of lexicon, but have different origins.
Distinctive tonal variations emerged during the subsequent expansion of the Vietnamese language and people into what is now central and southern Vietnam through conquest of the ancient nation of Champa and the Khmer people of the Mekong Delta in the vicinity of present-day Ho Chi Minh City, also known as Saigon.
Vietnamese was primarily influenced by Chinese, which came to predominate politically in the 2nd century BC. After Vietnam achieved independence in the 10th century, the ruling class adopted Literary Chinese as the medium of government, scholarship and literature. With the dominance of Chinese came radical importation of Chinese vocabulary and grammatical influence. Much of the Vietnamese lexicon in all realms consists of Sino-Vietnamese words.
When France invaded Vietnam in the late 19th century, French gradually replaced Chinese as the official language in education and government. Vietnamese adopted many French terms, such as đầm (dame, from madame), ga (train station, from gare), sơ mi (shirt, from chemise), and búp bê (doll, from poupée). In addition, many Sino-Vietnamese terms were devised for Western ideas imported through the French.

- Ancient Vietnamese, the language represented by chu nom characters (c. 15th century) and the Chinese–Vietnamese glossary Hua-yi Yi-yu (c. 16th century). By this point a tone split had happened in the language, leading to six tones but a loss of contrastive voicing among consonants.

^1 According to Ferlus, */tʃ/ and */ʄ/ are not accepted by all researchers. Ferlus 1992 had an additional phoneme */dʒ/, and had the preglottalized consonant */ʔj/ in place of the implosive consonant */ʄ/. Note that the latter two sounds are not all that different, both being voiced palatals and glottalic.
^2 The fricatives indicated above in parentheses developed as allophones of stop consonants occurring between vowels (i.e. when a minor syllable occurred). These fricatives were not present in Proto-Viet–Muong, as indicated by their absence in Muong, 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:
- *p, *b > /β/
- *t, *d > /ð/
- *k, *ɡ > /ɣ/
- *s, *ɕ > /ς/
- *c, *ɟ, *tʃ > /ʝ/
^4 It is unclear what this sound was. According to Ferlus 1992, in the Archaic Vietnamese period (c. 10th century AD, when Sino-Vietnamese vocabulary was borrowed) it was *ɽ, distinct at that time from *r.
The following initial clusters occurred, with outcomes indicated:
- *pr, *br, *tr, *dr, *kr, *gr > /kʰr/ > /ks/ > s
- *pl, *bl > MV bl > Northern gi, Southern tr
- *kl, *gl > MV tl > tr
- ml > MV ml > mnh > nh
- *kj > gi
Note also that a large number of words were borrowed from Middle Chinese, forming part of the Sino-Vietnamese vocabulary. These caused the original introduction of the retroflex sounds /ʂ/ and /ʈ/ (modern s, tr) into the language.
Origin of the 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:
Register Initial consonant Smooth ending Glottal ending Fricative ending High (first) register Voiceless A1 ngang "level" B1 sắc "sharp" C1 hỏi "asking" Low (second) register Voiced A2 huyền "hanging" B2 nặng "heavy" C2 ngã "tumbling"
Glottal-ending syllables ended with a glottal stop /ʔ/, while fricative-ending syllables ended with /s/ or /h/. Both types of syllables could co-occur with a resonant (e.g. /m/ or /n/).
At some point, a tone split occurred, as in many other Southeast Asian languages. Essentially, an allophonic distinction developed in the tones, whereby the tones in syllables with voiced initials were pronounced differently from those with voiceless initials. (Approximately speaking, the voiced allotones were pronounced with additional breathy voice or creaky voice and with lowered pitch. The quality difference predominates in today's northern varieties, e.g. in Hanoi, while in the southern varieties the pitch difference predominates, as in Ho Chi Minh City.) Subsequent to this, the plain-voiced stops became voiceless and the allotones became new phonemic tones. Note that the implosive stops were unaffected, and in fact developed tonally as if they were unvoiced. (This behavior is common to all East Asian languages with implosive stops.)
As noted above, Proto-Viet–Muong had sesquisyllabic words with an initial minor syllable (in addition to, and independent of, initial clusters in the main syllable). When a minor syllable occurred, the main syllable's initial consonant was intervocalic and as a result suffered lenition, 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 /l/ and /ŋ/ 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.)
The writing system used for Vietnamese is based closely on the system developed by Alexandre de Rhodes for his Vietnamese–Portuguese–Latin dictionary, published in 1651. It reflects the pronunciation of the Vietnamese of Hanoi at that time, a stage commonly termed Middle Vietnamese (tiếng Việt trung đại). The pronunciation of the "rime" of the syllable, i.e. all parts other than the initial consonant (optional /w/ 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:
Labial Dental/Alveolar Retroflex Palatal Velar Glottal Stop voiceless p [p]1 t [t] tr [ʈ] ch [c] c/k [k] aspirated ph [pʰ] th [tʰ] kh [kʰ] voiced glottalized b [ɓ] đ [ɗ] Fricative voiceless s [ʂ] x [ɕ] h [h] voiced ꞗ [β]2 d [ð] gi [ʝ] g/gh [ɣ] Nasal m [m] n [n] nh [ɲ] ng/ngh [ŋ] Approximant v/u/o [w] l [l] r [ɹ] y/i/ĕ [j]3
^1 [p] occurs only at the end of a syllable.
^2 This symbol, "Latin small letter B with flourish", looks like: . It has a rounded hook that starts halfway up the left side (where the top of the curved part of the b meets the vertical, straight part) and curves about 180 degrees counterclockwise, ending below the bottom-left corner.
^3 [j] does not occur at the beginning of a syllable, but can occur at the end of a syllable, where it is notated i or y (with the difference between the two often indicating differences in the quality or length of the preceding vowel), and after /ð/ and /β/, where it is notated ĕ. This ĕ, and the /j/ it notated, have disappeared from the modern language.
Note that b [ɓ] and p [p] never contrast in any position, suggesting that they are allophones; likewise for gi [ʝ] and y/i/ĕ [j].
The language also has three clusters at the beginning of syllables, which have since disappeared:
- tl /tl/ > modern tr
- bl /ɓl/ > modern gi (Northern), tr (Southern)
- ml /ml/ > mnh /mɲ/ > modern nh
Most of the unusual correspondences between spelling and modern pronunciation are explained by Middle Vietnamese. Note in particular:
- de Rhodes' system has two different b letters, a regular b and a "hooked" b in which the upper section of the curved part of the b extends leftward past the vertical bar and curls down again in a semicircle. This apparently represented a voiced bilabial fricative /β/. Within a century or so, both /β/ and /w/ had merged as /v/, spelled as v.
- de Rhodes' system has a second medial glide /j/ that is written ĕ and appears in some words with initial d and hooked b. These later disappear.
- đ /ɗ/ was (and still is) alveolar, whereas d /ð/ was dental. The choice of symbols was based on the dental rather than alveolar nature of /d/ and its allophone [ð] in Spanish and other Romance languages. The inconsistency with the symbols assigned to /ɓ/ vs. /β/ was based on the lack of any such place distinction between the two, with the result that the stop consonant /ɓ/ appeared more "normal" than the fricative /β/. In both cases, the implosive nature of the stops does not appear to have had any role in the choice of symbol.
- x was alveolopalatal /ɕ/ rather than dental /s/, as in the modern language. In 17th-century Portuguese, the common language of the Jesuits, s was an apicoalveolar sibilant /s̺/ (as still in much of Spain and some parts of Portugal), while x was a palatoalveolar /ʃ/. The similarity of apicoalveolar /s̺/ to the Vietnamese retroflex /ʂ/ led to the assignment of s and x as above.
De Rhodes' orthography also made use of an apex diacritic to indicate a final labial-velar nasal /ŋ͡m/, an allophone of /ŋ/ that is peculiar to the Hanoi dialect to the present day. This diacritic is often mistaken for a tilde in modern reproductions of early Vietnamese writing.
A language game known as nói lái is used by Vietnamese speakers. Nói lái involves switching the tones in a pair of words and also the order of the two words or the first consonant and rime of each word; the resulting nói lái pair preserves the original sequence of tones. Some examples:
Original phrase Phrase after nói lái transformation Structural change đái dầm "(child) wet their pants" → dấm đài (nonsense words) word order and tone switch chửa hoang "pregnancy out of wedlock" → hoảng chưa "scared yet?" word order and tone switch bầy tôi "all the king's subjects" → bồi tây "French waiter" initial consonant, rime, and tone switch bí mật "secrets" → bật mí "revealing secrets" initial consonant and rime switch
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.
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.
Nonsense syllable Target word Intermediate form with prefixed syllable Resulting "secret" word la phở "beef or chicken noodle soup" → la phở → lơ phả la ăn "to eat" → la ăn → lăn a la hoàn cảnh "situation" → la hoàn la cảnh → loan hà lanh cả chim hoàn cảnh "situation" → chim hoàn chim cảnh → choan hìm chanh kỉm
This language game is often used as a "secret" or "coded" language useful for obscuring messages from adult comprehension.
See "The Tale of Kieu" for an extract of the first six lines of Truyện Kiều, an epic narrative poem by the celebrated poet Nguyễn Du, 阮攸), which is often considered the most significant work of Vietnamese literature. It was originally written in Nôm (titled Đoạn Trường Tân Thanh 斷腸新聲) and is widely taught in Vietnam today.

- There are different descriptions of Hanoi vowels. Another common description is that of Thompson (1965):
Front Central Back unrounded rounded Close i [i] ư [ɯ] u [u] Close-mid ê [e] ơ [ɤ] ô [o] Open-mid e [ɛ] â [ʌ] o [ɔ] Open a [a] ă [ɐ]
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 [ɐ] as being slightly higher (upper low) than a [a].
- In Vietnamese, diphthongs are âm đôi.
- The diphthongs and triphthongs as described by Thompson can be compared with the description above:
Thompson's diphthongs Vowel nucleus Front offglide Back offglide Centering offglide i – iu [iʊ̯] ia~iê [iə̯] ê – êu [eʊ̯] – e – eo [ɛʊ̯] – ư ưi [ɯɪ̯] ưu [ɯʊ̯] ưa~ươ [ɯə̯] â ây [ʌɪ̯] âu [ʌʊ̯] – ơ ơi [ɤɪ̯] – – ă ay [ɐɪ̯] au [ɐʊ̯] – a ai [aɪ̯] ao [aʊ̯] – u ui [uɪ̯] – ua~uô [uə̯] ô ôi [oɪ̯] – – o oi [ɔɪ̯] – –
Thompson's triphthongs Centering diphthong Front offglide Back offglide ia ~ iê – iêu [iə̯ʊ̯] ưa ~ ươ ươi [ɨə̯ɪ̯] ươu [ɨə̯ʊ̯] ua ~ uô uôi [uə̯ɪ̯] –
- The lack of diphthong consisting of a ơ + back offglide (i.e., [əːʊ̯]) is an apparent gap.
- Called thanh điệu in Vietnamese
- Note that the name of each tone has the corresponding tonal diacritic on the vowel.

- In southern dialects, v is reported to have a spelling pronunciation (i.e., the spelling influences pronunciation) of [vj] or [bj] among educated speakers. However, educated speakers revert to usual [j] in more relaxed speech. Less educated speakers have [j] more consistently throughout their speech. See: Thompson (1959), Thompson (1965: 85, 89, 93, 97-98).
- Gregerson (1981) notes that this variation was present in de Rhodes's time in some initial consonant clusters: mlẽ ~ mnhẽ "reason" (cf. modern Vietnamese lẽ "reason").
- Comparison note: As such its grammar relies on word order and sentence structure rather than morphology (in which word changes through inflection). Whereas European languages tend to use morphology to express tense, Vietnamese uses grammatical particles or syntactic constructions.
