114-708: Rhus succedanea L. Toxicodendron succedaneum , the wax tree , Japanese Hazenoki tree ( Sumac or wax tree ), sơn in Vietnamese or charão in Portuguese , is a flowering plant species in the genus Toxicodendron found in Asia, although it has been planted elsewhere, most notably Australia and New Zealand. It is a large shrub or tree , up to 8 m tall, somewhat similar to a sumac tree. Because of its beautiful autumn foliage, it has been planted outside Asia as an ornamental plant , often by gardeners who were apparently unaware of

228-560: A cytotoxic biflavonoid . Its stems are also a commercial source of fisetin , extracted in China. It is used to produce lacquer . In Vietnam, lacquer is used to produce lacquer paintings , known as sơn mài, from resin of the tree. In East Asia, in particular in Japan, traditional candle fuel (also called Japan wax ) was produced, among other sumac plants, from Toxicodendron succedaneum crushed fruits rather than beeswax or animal fats. Japan's wax

342-437: A logographic script using Chinese characters ( chữ Hán ) to represent Sino-Vietnamese vocabulary and some native Vietnamese words, together with many locally invented characters representing other words. Early linguistic work in the late 19th and early 20th centuries ( Logan 1852, Forbes 1881, Müller 1888, Kuhn 1889, Schmidt 1905, Przyluski 1924, and Benedict 1942) classified Vietnamese as belonging to

456-636: A minor syllable 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

570-549: A determination, and simply assign the flap in both cases to a single archiphoneme, written (for example) //D// . Further mergers in English are plosives after /s/ , where /p, t, k/ conflate with /b, d, ɡ/ , as suggested by the alternative spellings sketti and sghetti . That is, there is no particular reason to transcribe spin as /ˈspɪn/ rather than as /ˈsbɪn/ , other than its historical development, and it might be less ambiguously transcribed //ˈsBɪn// . A morphophoneme

684-462: A given language may be highly distorted; this is the case with English, for example. The correspondence between symbols and phonemes in alphabetic writing systems is not necessarily a one-to-one correspondence . A phoneme might be represented by a combination of two or more letters ( digraph , trigraph , etc. ), like ⟨sh⟩ in English or ⟨sch⟩ in German (both representing

798-447: A main vowel component followed by a shorter semivowel offglide /j/ or /w/ . There are restrictions on the high offglides: /j/ cannot occur after a front vowel (i, ê, e) nucleus and /w/ cannot occur after a back vowel (u, ô, o) nucleus. The correspondence between the orthography and pronunciation is complicated. For example, the offglide /j/ is usually written as i ; however, it may also be represented with y . In addition, in

912-406: A near minimal pair. The reason why this is still acceptable proof of phonemehood is that there is nothing about the additional difference (/r/ vs. /l/) that can be expected to somehow condition a voicing difference for a single underlying postalveolar fricative. One can, however, find true minimal pairs for /ʃ/ and /ʒ/ if less common words are considered. For example, ' Confucian ' and 'confusion' are

1026-448: A paper published in 1856. Later, in 1920, French-Polish linguist Jean Przyluski found that Mường is more closely related to Vietnamese than other Mon–Khmer languages, and a Viet–Muong subgrouping was established, also including Thavung , Chut , Cuoi , etc. The term "Vietic" was proposed by Hayes (1992), who proposed to redefine Viet–Muong as referring to a subbranch of Vietic containing only Vietnamese and Mường . The term " Vietic "

1140-483: A phoneme has more than one allophone , the one actually heard at a given occurrence of that phoneme may be dependent on the phonetic environment (surrounding sounds). Allophones that normally cannot appear in the same environment are said to be in complementary distribution . In other cases, the choice of allophone may be dependent on the individual speaker or other unpredictable factors. Such allophones are said to be in free variation , but allophones are still selected in

1254-532: A process of tonogenesis , in which distinctions formerly expressed by final consonants became phonemic tonal distinctions when those consonants disappeared. These characteristics have become part of many of the genetically unrelated languages of Southeast Asia; for example, Tsat (a member of the Malayo-Polynesian group within Austronesian ), and Vietnamese each developed tones as a phonemic feature. After

It also grants the community the right to use Vietnamese with public authorities and in courts anywhere in the country. Vietnamese is taught in schools and institutions outside of Vietnam, a large part contributed by its diaspora . In countries with Vietnamese-speaking communities Vietnamese language education largely serves as

1482-534: A role to link descendants of Vietnamese immigrants to their ancestral culture. In neighboring countries and vicinities near Vietnam such as Southern China, Cambodia, Laos, and Thailand, Vietnamese as a foreign language is largely due to trade, as well as recovery and growth of the Vietnamese economy. Since the 1980s, Vietnamese language schools ( trường Việt ngữ/ trường ngôn ngữ Tiếng Việt ) have been established for youth in many Vietnamese-speaking communities around

1596-401: A set (or equivalence class ) of spoken sound variations that are nevertheless perceived as a single basic unit of sound by the ordinary native speakers of a given language. While phonemes are considered an abstract underlying representation for sound segments within words, the corresponding phonetic realizations of those phonemes—each phoneme with its various allophones—constitute

1710-417: A set of phonemes, and these different systems or solutions are not simply correct or incorrect, but may be regarded only as being good or bad for various purposes". The linguist F. W. Householder referred to this argument within linguistics as "God's Truth" (i.e. the stance that a given language has an intrinsic structure to be discovered) vs. "hocus-pocus" (i.e. the stance that any proposed, coherent structure

1824-456: A simple /k/ , colloquial Samoan lacks /t/ and /n/ , while Rotokas and Quileute lack /m/ and /n/ . During the development of phoneme theory in the mid-20th century, phonologists were concerned not only with the procedures and principles involved in producing a phonemic analysis of the sounds of a given language, but also with the reality or uniqueness of the phonemic solution. These were central concerns of phonology . Some writers took

1938-435: A single morphophoneme, which might be transcribed (for example) //z// or |z| , and which is realized phonemically as /s/ after most voiceless consonants (as in cat s ) and as /z/ in other cases (as in dog s ). All known languages use only a small subset of the many possible sounds that the human speech organs can produce, and, because of allophony , the number of distinct phonemes will generally be smaller than

2052-512: A single phoneme: the one traditionally represented in the IPA as /t/ . For computer-typing purposes, systems such as X-SAMPA exist to represent IPA symbols using only ASCII characters. However, descriptions of particular languages may use different conventional symbols to represent the phonemes of those languages. For languages whose writing systems employ the phonemic principle , ordinary letters may be used to denote phonemes, although this approach

2166-411: A speaker pronounces /p/ are phonetic and written between brackets, like [p] for the p in spit versus [pʰ] for the p in pit , which in English is an aspirated allophone of /p/ (i.e., pronounced with an extra burst of air). There are many views as to exactly what phonemes are and how a given language should be analyzed in phonemic terms. Generally, a phoneme is regarded as an abstraction of

2280-542: A specific phonetic context, not the other way around. The term phonème (from Ancient Greek : φώνημα , romanized :  phōnēma , "sound made, utterance, thing spoken, speech, language" ) was reportedly first used by A. Dufriche-Desgenettes in 1873, but it referred only to a speech sound. The term phoneme as an abstraction was developed by the Polish linguist Jan Baudouin de Courtenay and his student Mikołaj Kruszewski during 1875–1895. The term used by these two

2394-511: 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

2508-546: A third of the Vietnamese lexicon in all realms, and may account for as much as 60% of the vocabulary used in formal texts. Vietic languages were confined to the northern third of modern Vietnam until the "southward advance" ( Nam tiến ) from the late 15th century. The conquest of the ancient nation of Champa and the conquest of the Mekong Delta led to an expansion of the Vietnamese people and language, with distinctive local variations emerging. After France invaded Vietnam in

2622-467: A unique phoneme in such cases, since to do so would mean providing redundant or even arbitrary information – instead they use the technique of underspecification . An archiphoneme is an object sometimes used to represent an underspecified phoneme. An example of neutralization is provided by the Russian vowels /a/ and /o/ . These phonemes are contrasting in stressed syllables, but in unstressed syllables

2736-452: A valid minimal pair. Besides segmental phonemes such as vowels and consonants, there are also suprasegmental features of pronunciation (such as tone and stress , syllable boundaries and other forms of juncture , nasalization and vowel harmony ), which, in many languages, change the meaning of words and so are phonemic. Phonemic stress is encountered in languages such as English. For example, there are two words spelled invite , one

2850-419: Is a byproduct of lacquer manufacture. It is not a true wax but a fat that contains 10–15% palmitin , stearin , and olein with about 1% japanic acid (1,21-heneicosanedioic acid). Japan wax is sold in flat squares or disks and has a rancid odor. It is extracted by expression, heat, or the action of solvents . The fatty-acid methyl ester of the kernel oil meets all of the major biodiesel requirements in

2964-418: Is a purely articulatory system apart from the use of the acoustic term 'sibilant'. In the description of some languages, the term chroneme has been used to indicate contrastive length or duration of phonemes. In languages in which tones are phonemic, the tone phonemes may be called tonemes . Though not all scholars working on such languages use these terms, they are by no means obsolete. By analogy with

3078-414: Is a theoretical unit at a deeper level of abstraction than traditional phonemes, and is taken to be a unit from which morphemes are built up. A morphophoneme within a morpheme can be expressed in different ways in different allomorphs of that morpheme (according to morphophonological rules). For example, the English plural morpheme -s appearing in words such as cats and dogs can be considered to be

3192-439: Is a verb and is stressed on the second syllable, the other is a noun and stressed on the first syllable (without changing any of the individual sounds). The position of the stress distinguishes the words and so a full phonemic specification would include indication of the position of the stress: /ɪnˈvaɪt/ for the verb, /ˈɪnvaɪt/ for the noun. In other languages, such as French , word stress cannot have this function (its position

3306-516: Is also spoken by the Jing people traditionally residing on three islands (now joined to the mainland) off Dongxing in southern Guangxi Province , China . A large number of Vietnamese speakers also reside in neighboring countries of Cambodia and Laos . In the United States, Vietnamese is the sixth most spoken language , with over 1.5 million speakers, who are concentrated in a handful of states. It

3420-417: Is any set of similar speech sounds that is perceptually regarded by the speakers of a language as a single basic sound—a smallest possible phonetic unit—that helps distinguish one word from another. All languages contains phonemes (or the spatial-gestural equivalent in sign languages ), and all spoken languages include both consonant and vowel phonemes. Phonemes are primarily studied under

3534-641: Is as good as any other). Different analyses of the English vowel system may be used to illustrate this. The article English phonology states that "English has a particularly large number of vowel phonemes" and that "there are 20 vowel phonemes in Received Pronunciation, 14–16 in General American and 20–21 in Australian English". Although these figures are often quoted as fact, they actually reflect just one of many possible analyses, and later in

3648-411: Is called a minimal pair for the two alternative phones in question (in this case, [kʰ] and [k] ). The existence of minimal pairs is a common test to decide whether two phones represent different phonemes or are allophones of the same phoneme. To take another example, the minimal pair t ip and d ip illustrates that in English, [t] and [d] belong to separate phonemes, /t/ and /d/ ; since

3762-500: Is generally predictable) and so it is not phonemic (and therefore not usually indicated in dictionaries). Phonemic tones are found in languages such as Mandarin Chinese in which a given syllable can have five different tonal pronunciations: The tone "phonemes" in such languages are sometimes called tonemes . Languages such as English do not have phonemic tone, but they use intonation for functions such as emphasis and attitude. When

3876-460: Is highly analytic and is tonal . It has head-initial directionality, with subject–verb–object order and modifiers following the words they modify. It also uses noun classifiers . Its vocabulary has had significant influence from Middle Chinese and loanwords from French . Although it is often mistakenly thought as being an monosyllabic language, Vietnamese words typically consist of from one to many as eight individual morphemes or syllables;

3990-415: 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. The language also has three clusters at

4104-430: Is notoriously a fire in a wooden stove." This approach was opposed to that of Edward Sapir , who gave an important role to native speakers' intuitions about where a particular sound or group of sounds fitted into a pattern. Using English [ŋ] as an example, Sapir argued that, despite the superficial appearance that this sound belongs to a group of three nasal consonant phonemes (/m/, /n/ and /ŋ/), native speakers feel that

4218-408: Is often imperfect, as pronunciations naturally shift in a language over time, rendering previous spelling systems outdated or no longer closely representative of the sounds of the language (see § Correspondence between letters and phonemes below). A phoneme is a sound or a group of different sounds perceived to have the same function by speakers of the language or dialect in question. An example

4332-522: Is often mistaken for a tilde in modern reproductions of early Vietnamese writing. As a result of emigration , Vietnamese speakers are also found in other parts of Southeast Asia , East Asia , North America , Europe , and Australia . Vietnamese has also been officially recognized as a minority language in the Czech Republic . As the national language, Vietnamese is the lingua franca in Vietnam. It

4446-492: Is possible to discover the phonemes of a language purely by examining the distribution of phonetic segments. Referring to mentalistic definitions of the phoneme, Twaddell (1935) stated "Such a definition is invalid because (1) we have no right to guess about the linguistic workings of an inaccessible 'mind', and (2) we can secure no advantage from such guesses. The linguistic processes of the 'mind' as such are quite simply unobservable; and introspection about linguistic processes

Tones differ in: Tone is indicated by diacritics written above or below the vowel (most of the tone diacritics appear above the vowel; except 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: Phoneme A phoneme ( / ˈ f oʊ n iː m / )

4902-497: Is the English phoneme /k/ , which occurs in words such as c at , k it , s c at , s k it . Although most native speakers do not notice this, in most English dialects, the "c/k" sounds in these words are not identical: in kit [kʰɪt] , the sound is aspirated, but in skill [skɪl] , it is unaspirated. The words, therefore, contain different speech sounds , or phones , transcribed [kʰ] for

In the Czech Republic , 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

Sounds that are perceived as phonemes vary by languages and dialects, so that [ n ] and [ ŋ ] are separate phonemes in English since they distinguish words like sin from sing ( /sɪn/ versus /sɪŋ/ ), yet they comprise a single phoneme in some other languages, such as Spanish, in which [pan] and [paŋ] for instance are merely interpreted by Spanish speakers as regional or dialect-specific ways of pronouncing

Vietnamese is the third most spoken language in Australia other than English, after Mandarin and Arabic. In France, it is the most spoken Asian language and the eighth most spoken immigrant language at home. Vietnamese is the sole official and national language of Vietnam. It

Austroasiatic is believed to have dispersed around 2000 BC. The arrival of the agricultural Phùng Nguyên culture in

5472-446: Is written with two Chinese characters or in a composite character made of two different characters. This conveys the transformation of the Vietnamese lexicon from sesquisyllabic to fully monosyllabic under the pressure of Chinese linguistic influence, characterized by linguistic phenomena such as the reduction of minor syllables; loss of affixal morphology drifting towards analytical grammar; simplification of major syllable segments, and

5586-765: The Kam–Sui languages have six to nine tones (depending on how they are counted), and the Kam-Sui Dong language has nine to 15 tones by the same measure. One of the Kru languages , Wobé , has been claimed to have 14, though this is disputed. The most common vowel system consists of the five vowels /i/, /e/, /a/, /o/, /u/ . The most common consonants are /p/, /t/, /k/, /m/, /n/ . Relatively few languages lack any of these consonants, although it does happen: for example, Arabic lacks /p/ , standard Hawaiian lacks /t/ , Mohawk and Tlingit lack /p/ and /m/ , Hupa lacks both /p/ and

In 1850, British lawyer James Richardson Logan detected striking similarities between the Korku language in Central India and Vietnamese. He suggested that Korku , Mon , and Vietnamese were part of what he termed "Mon–Annam languages" in

Other ways the second of these has been notated include |m-n-ŋ| , {m, n, ŋ} and //n*// . Another example from English, but this time involving complete phonetic convergence as in the Russian example, is the flapping of /t/ and /d/ in some American English (described above under Biuniqueness ).

5928-587: The Red River Delta at that time may correspond to the Vietic branch. This ancestral Vietic was typologically very different from later Vietnamese. It was polysyllabic, or rather sesquisyllabic , with roots consisting of a reduced syllable followed by a full syllable, and featured many consonant clusters. Both of these features are found elsewhere in Austroasiatic and in modern conservative Vietic languages south of

6042-597: 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"). In some cases, they are based on their Middle Vietnamese pronunciation; since that period, ph and kh (but not th ) have evolved from aspirated stops into fricatives (like Greek phi and chi ), while d and gi have collapsed and converged together (into /z/ in

6156-867: The ASL signs for father and mother differ minimally with respect to location while handshape and movement are identical; location is thus contrastive. Stokoe's terminology and notation system are no longer used by researchers to describe the phonemes of sign languages; William Stokoe 's research, while still considered seminal, has been found not to characterize American Sign Language or other sign languages sufficiently. For instance, non-manual features are not included in Stokoe's classification. More sophisticated models of sign language phonology have since been proposed by Brentari , Sandler , and Van der Kooij. Cherology and chereme (from Ancient Greek : χείρ "hand") are synonyms of phonology and phoneme previously used in

The oldest layer of loans from Chinese into northern Vietic (which would become the Viet–Muong subbranch) date from this period.

By contrast, some other sounds would cause a change in meaning if substituted: for example, substitution of

7296-471: The beginning of syllables, which have since disappeared: Most of the unusual correspondences between spelling and modern pronunciation are explained by Middle Vietnamese. Note in particular: De Rhodes's orthography also made use of an apex diacritic, as in o᷄ and u᷄ , 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

It reflects the pronunciation of the Vietnamese of Hanoi at that time,

In order to assign such an instance of [ə] to one of the phonemes /a/ and /o/ , it is necessary to consider morphological factors (such as which of the vowels occurs in other forms of the words, or which inflectional pattern is followed). In some cases even this may not provide an unambiguous answer. A description using

Essentially, an allophonic distinction developed in

However, because changes in the spoken language are often not accompanied by changes in the established orthography (as well as other reasons, including dialect differences, the effects of morphophonology on orthography, and the use of foreign spellings for some loanwords ), the correspondence between spelling and pronunciation in

Similarly, u and o indicate different pronunciations of the main vowel: au = ă + /w/ , ao = a + /w/ . Thus, thau "brass" is [tʰāw] while thao "raw silk" is [tʰāːw] . The consonants that occur in Vietnamese are listed below in

Absolute neutralization is a phenomenon in which a segment of the underlying representation is not realized in any of its phonetic representations (surface forms). The term was introduced by Paul Kiparsky (1968), and contrasts with contextual neutralization where some phonemes are not contrastive in certain environments. Some phonologists prefer not to specify

8322-434: The following: Some phonotactic restrictions can alternatively be analyzed as cases of neutralization. See Neutralization and archiphonemes below, particularly the example of the occurrence of the three English nasals before stops. Biuniqueness is a requirement of classic structuralist phonemics. It means that a given phone , wherever it occurs, must unambiguously be assigned to one and only one phoneme. In other words,

8436-516: The idea of a cognitive or psycholinguistic function for the phoneme. Later, it was used and redefined in generative linguistics , most famously by Noam Chomsky and Morris Halle , and remains central to many accounts of the development of modern phonology . As a theoretical concept or model, though, it has been supplemented and even replaced by others. Some linguists (such as Roman Jakobson and Morris Halle ) proposed that phonemes may be further decomposable into features , such features being

8550-400: The language perceive two sounds as significantly different even if no exact minimal pair exists in the lexicon. It is challenging to find a minimal pair to distinguish English / ʃ / from / ʒ / , yet it seems uncontroversial to claim that the two consonants are distinct phonemes. The two words 'pressure' / ˈ p r ɛ ʃ ər / and 'pleasure' / ˈ p l ɛ ʒ ər / can serve as

8664-446: The late 19th century, French gradually replaced Literary 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 ), resulting in a language that was Austroasiatic but with major Sino-influences and some minor French influences from

8778-427: 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

8892-461: The majority of Vietnamese vocabulary are disyllabic and trisyllabic words. Vietnamese is written using the Vietnamese alphabet ( chữ Quốc ngữ ). The alphabet is based on the Latin script and was officially adopted in the early 20th century during French rule of Vietnam . It uses digraphs and diacritics to mark tones and some phonemes . Vietnamese was historically written using chữ Nôm ,

9006-532: The mapping between phones and phonemes is required to be many-to-one rather than many-to-many . The notion of biuniqueness was controversial among some pre- generative linguists and was prominently challenged by Morris Halle and Noam Chomsky in the late 1950s and early 1960s. An example of the problems arising from the biuniqueness requirement is provided by the phenomenon of flapping in North American English . This may cause either /t/ or /d/ (in

9120-457: The meaning of a word. In those languages, therefore, the two sounds represent different phonemes. For example, in Icelandic , [kʰ] is the first sound of kátur , meaning "cheerful", but [k] is the first sound of gátur , meaning "riddles". Icelandic, therefore, has two separate phonemes /kʰ/ and /k/ . A pair of words like kátur and gátur (above) that differ only in one phone

9234-489: The minimal triplet sum /sʌm/ , sun /sʌn/ , sung /sʌŋ/ . However, before a stop such as /p, t, k/ (provided there is no morpheme boundary between them), only one of the nasals is possible in any given position: /m/ before /p/ , /n/ before /t/ or /d/ , and /ŋ/ before /k/ , as in limp, lint, link ( /lɪmp/ , /lɪnt/ , /lɪŋk/ ). The nasals are therefore not contrastive in these environments, and according to some theorists this makes it inappropriate to assign

9348-415: The nasal phones heard here to any one of the phonemes (even though, in this case, the phonetic evidence is unambiguous). Instead they may analyze these phonemes as belonging to a single archiphoneme, written something like //N// , and state the underlying representations of limp, lint, link to be //lɪNp//, //lɪNt//, //lɪNk// . This latter type of analysis is often associated with Nikolai Trubetzkoy of

9462-497: The north and /j/ in the south). 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 /c/, /ɲ/ contrasting with syllable-final t , c /t/, /k/ and n , ng /n/, /ŋ/ and identifies final ch with

9576-636: The number of identifiably different sounds. Different languages vary considerably in the number of phonemes they have in their systems (although apparent variation may sometimes result from the different approaches taken by the linguists doing the analysis). The total phonemic inventory in languages varies from as few as 9–11 in Pirahã and 11 in Rotokas to as many as 141 in ǃXũ . The number of phonemically distinct vowels can be as low as two, as in Ubykh and Arrernte . At

9690-556: The other extreme, the Bantu language Ngwe has 14 vowel qualities, 12 of which may occur long or short, making 26 oral vowels, plus six nasalized vowels, long and short, making a total of 38 vowels; while !Xóõ achieves 31 pure vowels, not counting its additional variation by vowel length, by varying the phonation . As regards consonant phonemes, Puinave and the Papuan language Tauade each have just seven, and Rotokas has only six. !Xóõ , on

9804-461: The other hand, has somewhere around 77, and Ubykh 81. The English language uses a rather large set of 13 to 21 vowel phonemes, including diphthongs, although its 22 to 26 consonants are close to average. Across all languages, the average number of consonant phonemes per language is about 22, while the average number of vowel phonemes is about 8. Some languages, such as French , have no phonemic tone or stress , while Cantonese and several of

9918-449: The phoneme /ʃ/ ). Also a single letter may represent two phonemes, as in English ⟨x⟩ representing /gz/ or /ks/ . There may also exist spelling/pronunciation rules (such as those for the pronunciation of ⟨c⟩ in Italian ) that further complicate the correspondence of letters to phonemes, although they need not affect the ability to predict the pronunciation from

10032-785: The phoneme, linguists have proposed other sorts of underlying objects, giving them names with the suffix -eme , such as morpheme and grapheme . These are sometimes called emic units . The latter term was first used by Kenneth Pike , who also generalized the concepts of emic and etic description (from phonemic and phonetic respectively) to applications outside linguistics. Languages do not generally allow words or syllables to be built of any arbitrary sequences of phonemes. There are phonotactic restrictions on which sequences of phonemes are possible and in which environments certain phonemes can occur. Phonemes that are significantly limited by such restrictions may be called restricted phonemes . In English, examples of such restrictions include

10146-405: The plain-voiced stops became voiceless and the allotones became new phonemic tones. 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

10260-418: The position expressed by Kenneth Pike : "There is only one accurate phonemic analysis for a given set of data", while others believed that different analyses, equally valid, could be made for the same data. Yuen Ren Chao (1934), in his article "The non-uniqueness of phonemic solutions of phonetic systems" stated "given the sounds of a language, there are usually more than one possible way of reducing them to

10374-546: 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] . 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 monophthongs ) and centering diphthongs, Vietnamese has closing diphthongs and triphthongs . The closing diphthongs and triphthongs consist of

10488-425: The same period there was disagreement about the correct basis for a phonemic analysis. The structuralist position was that the analysis should be made purely on the basis of the sound elements and their distribution, with no reference to extraneous factors such as grammar, morphology or the intuitions of the native speaker; this position is strongly associated with Leonard Bloomfield . Zellig Harris claimed that it

10602-501: The same phoneme. However, they are so dissimilar phonetically that they are considered separate phonemes. A case like this shows that sometimes it is the systemic distinctions and not the lexical context which are decisive in establishing phonemes. This implies that the phoneme should be defined as the smallest phonological unit which is contrastive at a lexical level or distinctive at a systemic level. Phonologists have sometimes had recourse to "near minimal pairs" to show that speakers of

10716-465: The same time, according to the following pattern: ^3 In Middle Vietnamese , the outcome of these sounds was written with a hooked b (ꞗ), representing a /β/ that was still distinct from v (then pronounced /w/ ). See below. ^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

10830-613: The same word ( pan : the Spanish word for "bread"). Such spoken variations of a single phoneme are known by linguists as allophones . Linguists use slashes in the IPA to transcribe phonemes but square brackets to transcribe more precise pronunciation details, including allophones; they describe this basic distinction as phonemic versus phonetic . Thus, the pronunciation patterns of tap versus tab , or pat versus bat , can be represented phonemically and are written between slashes (including /p/ , /b/ , etc.), while nuances of exactly how

10944-513: The same, but one of the parameters changes. However, the absence of minimal pairs for a given pair of phones does not always mean that they belong to the same phoneme: they may be so dissimilar phonetically that it is unlikely for speakers to perceive them as the same sound. For example, English has no minimal pair for the sounds [h] (as in h at ) and [ŋ] (as in ba ng ), and the fact that they can be shown to be in complementary distribution could be used to argue for their being allophones of

11058-412: The sound [t] would produce the different word s t ill , and that sound must therefore be considered to represent a different phoneme (the phoneme /t/ ). The above shows that in English, [k] and [kʰ] are allophones of a single phoneme /k/ . In some languages, however, [kʰ] and [k] are perceived by native speakers as significantly different sounds, and substituting one for the other can change

11172-641: The spelling and vice versa, provided the rules are consistent. Sign language phonemes are bundles of articulation features. Stokoe was the first scholar to describe the phonemic system of ASL . He identified the bundles tab (elements of location, from Latin tabula ), dez (the handshape, from designator ), and sig (the motion, from signation ). Some researchers also discern ori (orientation), facial expression or mouthing . Just as with spoken languages, when features are combined, they create phonemes. As in spoken languages, sign languages have minimal pairs which differ in only one phoneme. For instance,

11286-484: The split from Muong around the end of the first millennium AD, the following stages of Vietnamese are commonly identified: After expelling the Chinese at the beginning of the 10th century, the Ngô dynasty adopted Classical Chinese as the formal medium of government, scholarship and literature. With the dominance of Chinese came wholesale importation of Chinese vocabulary. The resulting Sino-Vietnamese vocabulary makes up about

11400-442: The study of sign languages . A chereme , as the basic unit of signed communication, is functionally and psychologically equivalent to the phonemes of oral languages, and has been replaced by that term in the academic literature. Cherology , as the study of cheremes in language, is thus equivalent to phonology. The terms are not in use anymore. Instead, the terms phonology and phoneme (or distinctive feature ) are used to stress

11514-499: The surface form that is actually uttered and heard. Allophones each have technically different articulations inside particular words or particular environments within words , yet these differences do not create any meaningful distinctions. Alternatively, at least one of those articulations could be feasibly used in all such words with these words still being recognized as such by users of the language. An example in American English

11628-505: 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 after the upper front vowels i /i/ and ê /e/ ; although they also occur after a , but in such cases are believed to have resulted from an earlier e /ɛ/ which diphthongized to ai (cf. ach from aic , anh from aing ). (See Vietnamese phonology: Analysis of final ch , nh for further details.) Each Vietnamese syllable

11742-567: 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,

11856-405: The true minimal constituents of language. Features overlap each other in time, as do suprasegmental phonemes in oral language and many phonemes in sign languages. Features could be characterized in different ways: Jakobson and colleagues defined them in acoustic terms, Chomsky and Halle used a predominantly articulatory basis, though retaining some acoustic features, while Ladefoged 's system

11970-403: The velar nasal is really the sequence [ŋɡ]/. The theory of generative phonology which emerged in the 1960s explicitly rejected the structuralist approach to phonology and favoured the mentalistic or cognitive view of Sapir. These topics are discussed further in English phonology#Controversial issues . Phonemes are considered to be the basis for alphabetic writing systems. In such systems

12084-422: 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.) Old Vietnamese/Ancient Vietnamese was a Vietic language which

12198-554: The vowel normally transcribed /aɪ/ would instead be /aj/ , /aʊ/ would be /aw/ and /ɑː/ would be /ah/ , or /ar/ in a rhotic accent if there is an ⟨r⟩ in the spelling. It is also possible to treat English long vowels and diphthongs as combinations of two vowel phonemes, with long vowels treated as a sequence of two short vowels, so that 'palm' would be represented as /paam/. English can thus be said to have around seven vowel phonemes, or even six if schwa were treated as an allophone of /ʌ/ or of other short vowels. In

12312-417: The words betting and bedding might both be pronounced [ˈbɛɾɪŋ] . Under the generative grammar theory of linguistics, if a speaker applies such flapping consistently, morphological evidence (the pronunciation of the related forms bet and bed , for example) would reveal which phoneme the flap represents, once it is known which morpheme is being used. However, other theorists would prefer not to make such

12426-410: The words have different meanings, English-speakers must be conscious of the distinction between the two sounds. Signed languages, such as American Sign Language (ASL), also have minimal pairs, differing only in (exactly) one of the signs' parameters: handshape, movement, location, palm orientation, and nonmanual signal or marker. A minimal pair may exist in the signed language if the basic sign stays

12540-452: The world such as in the United States , Germany and France . Vietnamese has a large number of vowels . Below is a vowel diagram of Vietnamese from Hanoi (including centering diphthongs ): Front and central 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

12654-447: The written symbols ( graphemes ) represent, in principle, the phonemes of the language being written. This is most obviously the case when the alphabet was invented with a particular language in mind; for example, the Latin alphabet was devised for Classical Latin, and therefore the Latin of that period enjoyed a near one-to-one correspondence between phonemes and graphemes in most cases, though

12768-679: Was fonema , the basic unit of what they called psychophonetics . Daniel Jones became the first linguist in the western world to use the term phoneme in its current sense, employing the word in his article "The phonetic structure of the Sechuana Language". The concept of the phoneme was then elaborated in the works of Nikolai Trubetzkoy and others of the Prague School (during the years 1926–1935), and in those of structuralists like Ferdinand de Saussure , Edward Sapir , and Leonard Bloomfield . Some structuralists (though not Sapir) rejected

12882-487: Was borrowed) it was * r̝ , distinct at that time from * r . The following initial clusters occurred, with outcomes indicated: 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. Proto-Viet–Muong did not have tones. Tones developed later in some of

12996-812: Was separated from Viet–Muong around the 9th century, and evolved into Middle Vietnamese by 16th century. The sources for the reconstruction of Old Vietnamese are Nom texts, such as the 12th-century/1486 Buddhist scripture Phật thuyết Đại báo phụ mẫu ân trọng kinh ("Sūtra explained by the Buddha on the Great Repayment of the Heavy Debt to Parents"), old inscriptions, and a late 13th-century (possibly 1293) Annan Jishi glossary by Chinese diplomat Chen Fu (c. 1259 – 1309). Old Vietnamese used Chinese characters phonetically where each word, monosyllabic in Modern Vietnamese,
