Turbulence
–
Turbulence or turbulent flow is a flow regime in fluid dynamics characterized by chaotic changes in pressure and flow velocity. It is in contrast to a flow regime, which occurs when a fluid flows in parallel layers. Turbulence is caused by kinetic energy in parts of a fluid flow. For this reason turbulence is easier to create in low viscosity fluids, in general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This would increase the energy needed to pump fluid through a pipe, however this effect can also be exploited by such as aerodynamic spoilers on aircraft, which deliberately spoil the laminar flow to increase drag and reduce lift. The onset of turbulence can be predicted by a constant called the Reynolds number. However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence creates a complex situation. Richard Feynman has described turbulence as the most important unsolved problem of classical physics, smoke rising from a cigarette is mostly turbulent flow. However, for the first few centimeters the flow is laminar, the smoke plume becomes turbulent as its Reynolds number increases, due to its flow velocity and characteristic length increasing. If the golf ball were smooth, the boundary layer flow over the front of the sphere would be laminar at typical conditions. However, the layer would separate early, as the pressure gradient switched from favorable to unfavorable. To prevent this happening, the surface is dimpled to perturb the boundary layer. This results in higher skin friction, but moves the point of boundary layer separation further along, resulting in form drag. The flow conditions in industrial equipment and machines. The external flow over all kind of such as cars, airplanes, ships. The motions of matter in stellar atmospheres, a jet exhausting from a nozzle into a quiescent fluid. As the flow emerges into this external fluid, shear layers originating at the lips of the nozzle are created and these layers separate the fast moving jet from the external fluid, and at a certain critical Reynolds number they become unstable and break down to turbulence. Biologically generated turbulence resulting from swimming animals affects ocean mixing, snow fences work by inducing turbulence in the wind, forcing it to drop much of its snow load near the fence

Taiwanese Hokkien
–
Taiwanese Hokkien, commonly known as Taiwanese, is a branched-off variant of Hokkien spoken natively by about 70% of the population of Taiwan. It is spoken by the Taiwanese Hoklo people, who descended from immigrants from southern Fujian during the Qing dynasty, the Pe̍h-ōe-jī romanization is a popular orthography for this variant of Hokkien. However, due to the popularity of Hokkien entertainment media from Taiwan, Taiwanese has become a prominent variety of Hokkien. Taiwanese Hokkien is a variety of Hokkien, a group of Southern Min dialects. Like many Min varieties, it has literary and colloquial layers of vocabulary. The literary layer can be traced to the late Tang dynasty, in contrast, the colloquial layers of Min varieties are believed to have branched from the mainstream of Chinese around the time of the Han dynasty. Regional variations within Taiwanese may be traced back to Hokkien variants spoken in Southern Fujian, specifically those from Quanzhou and Zhangzhou, Taiwanese Hokkien also contains loanwords from Japanese and the native Formosan languages. The literary form of Hokkien once flourished in Fujian and was brought to Taiwan by early emigrants, tale of the Lychee Mirror, a manuscript for a series of plays published during the Ming dynasty in 1566, is one of the earliest known works. This form of the language is now largely extinct, however, literary readings of the numbers are used in certain contexts such as reciting telephone numbers. During Yuan dynasty, Quanzhou became an international port for trade with the outside world. From that period onwards, due to political and economic reasons and this included the relatively undeveloped island of Formosa, starting around 1600. They brought with them their language, Hokkien. During the late Ming dynasty, due to chaos, there was increased migration from southern Fujian. The earliest immigrants who were involved in the development of Taiwan included pirate-merchants Chinese Peter, in 1621, Chinese Peter from Zhangzhou and his forces occupied Ponkan and started to develop Tirosen. After the death of Peter and another pirate, Li Dan of Quanzhou, by 1628, he had grown so powerful that the Ming court bestowed him the official title, Patrolling Admiral. In 1624, the number of Chinese in the island was about 25,000, during the reign of Chongzhen Emperor, there were frequent droughts in the Fujian region. Zheng and a Chinese official suggested to send victims to Taiwan, although this plan was never carried out, the Zheng family maintained an interest in Taiwan that would have dire consequences for the Dutch. In 1624 and 1626, the Dutch and Spanish forces occupied the Tainan and Keelung areas, during the 40 years of Dutch colonial rule of Taiwan, many Han Chinese from the Quanzhou, Zhangzhou and Hakka regions of mainland China were recruited to help develop Taiwan

Chinese characters
–
Chinese characters are logograms used in the writing of Chinese and some other Asian languages. In Standard Chinese, and sometimes also in English, they are called hànzì. They have been adapted to write a number of languages including, Japanese, where they are known as kanji, Korean, where they are known as hanja. Collectively, they are known as CJK characters, in English, they are sometimes called Han characters. Chinese characters constitute the oldest continuously used system of writing in the world, Chinese characters number in the tens of thousands, though most of them are minor graphic variants encountered only in historical texts. Studies in China have shown that literacy in written Chinese requires a knowledge of between three and four thousand characters. In Japan,2,136 are taught through secondary school, the characters used in Japan are distinct from those used in China in many respects. There are various national standard lists of characters, forms, in South Korea, when Chinese characters are used they are of the traditional variant and are almost identical to those used in places like Taiwan and Hong Kong. In Old Chinese, most words were monosyllabic and there was a correspondence between characters and words. Rather, a character almost always corresponds to a syllable that is also a morpheme. However, there are a few exceptions to this correspondence, including bisyllabic morphemes. Modern Chinese has many homophones, thus the same syllable may be represented by many characters. A single character may also have a range of meanings, or sometimes quite distinct meanings, cognates in the several varieties of Chinese are generally written with the same character. They typically have similar meanings, but often quite different pronunciations and these foreign adaptations of Chinese pronunciation are known as Sino-Xenic pronunciations, and have been useful in the reconstruction of Middle Chinese. When the script was first used in the late 2nd millennium BC, words of Old Chinese were generally monosyllabic, increasing numbers of polysyllabic words have entered the language from the Western Zhou period to the present day. The process has accelerated over the centuries as phonetic change has increased the number of homophones and it has been estimated that over two thirds of the 3,000 most common words in modern Standard Chinese are polysyllables, the vast majority of those being disyllables. The most common process has been to form compounds of existing words, words have also been created by adding affixes, reduplication and borrowing from other languages. Polysyllabic words are written with one character per syllable

Nahuatl
–
Nahuatl, known historically as Aztec, is a language or group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by an estimated 1.5 million Nahua peoples, all Nahuan languages are indigenous to Mesoamerica. Nahuatl has been spoken in central Mexico since at least the seventh century CE and it was the language of the Aztecs who dominated what is now central Mexico during the Late Postclassic period of Mesoamerican history. This early literary language based on the Tenochtitlan variety has been labeled Classical Nahuatl, today, Nahuan languages are spoken in scattered communities, mostly in rural areas throughout central Mexico and along the coastline. There are considerable differences among varieties, and some are mutually unintelligible, Huasteca Nahuatl, with over one million speakers, is the most-spoken variety. They have all been subject to varying degrees of influence from Spanish, No modern Nahuan languages are identical to Classical Nahuatl, but those spoken in and around the Valley of Mexico are generally more closely related to it than those on the periphery. Nahuan languages exhibit a complex morphology characterized by polysynthesis and agglutination, through a very long period of coexistence with the other indigenous Mesoamerican languages, they have absorbed many influences, coming to form part of the Mesoamerican language area. Many words from Nahuatl have been borrowed into Spanish, and since diffused into hundreds of other languages, most of these loanwords denote things indigenous to central Mexico which the Spanish heard mentioned for the first time by their Nahuatl names. English words of Nahuatl origin include avocado, chayote, chili, chocolate, atlatl, coyote, peyote, axolotl, as a language label, the term Nahuatl encompasses a group of closely related languages or divergent dialects within the Nahuan branch of the Uto-Aztecan language family. The Mexican Instituto Nacional de Lenguas Indígenas recognize 30 different individual varieties within the language group labeled Nahuatl, the Ethnologue recognizes 28 varieties with separate ISO codes. Sometimes the label also is used to include the Pipil language of El Salvador, within Mexico the question of whether to consider individual varieties to be languages or dialects of a single language is highly political. This article focuses on describing the history of the group. For details on individual varieties or subgroups, see the individual articles, in the past, the branch of Uto-Aztecan to which Nahuatl belongs has been called Aztecan. From the 1990s onward, the alternative designation Nahuan has been used as a replacement especially in Spanish-language publications. The Nahuan branch of Uto-Aztecan is widely accepted as having two divisions, General Aztec and Pochutec, General Aztec encompasses the Nahuatl and Pipil languages. Pochutec is a scantily attested language, which became extinct in the 20th century, other researchers have argued that Pochutec should be considered a divergent variant of the western periphery. Nahuatl denotes at least Classical Nahuatl together with related languages spoken in Mexico. The inclusion of Pipil into the group is debated, current subclassification of Nahuatl rests on research by Canger, Canger and Lastra de Suárez

Roundedness
–
In phonetics, vowel roundedness refers to the amount of rounding in the lips during the articulation of a vowel. It is labialization of a vowel, when a rounded vowel is pronounced, the lips form a circular opening, and unrounded vowels are pronounced with the lips relaxed. In most languages, front vowels tend to be unrounded, in the International Phonetic Alphabet vowel chart, rounded vowels are the ones that appear on the right in each pair of vowels. There are also diacritics, U+0339 ̹ COMBINING RIGHT HALF RING BELOW and U+031C ̜ COMBINING LEFT HALF RING BELOW, to greater and lesser degrees of rounding. The more and less rounded diacritics are also used with consonants to indicate degrees of labialization. There are two types of rounding, protrusion and compression. In protruded rounding, the corners of the mouth are drawn together, in compressed rounding, the corners of the mouth are drawn together, but the lips are also drawn together horizontally and do not protrude, with only their outer surface visible. That is, in protruded vowels the inner surfaces of the form the opening. Catford observes that back and central rounded vowels, such as German /o/ and /u/, are typically protruded, whereas front rounded vowels such as German /ø/ and /y/ are typically compressed. Back or central compressed vowels and front protruded vowels are uncommon, there are no dedicated IPA diacritics to represent the distinction, but the superscript IPA letter ⟨◌ᵝ⟩ can be used for compression and ⟨◌ʷ⟩, ⟨◌ᶣ⟩ or ⟨◌̫⟩ for protrusion. Compressed vowels may be pronounced either with the corners of the mouth drawn in, by some definitions rounded, or with the spread and, by the same definitions. The distinction may be transcribed ⟨ɨᵝ ɯᵝ⟩ and ⟨ʉᵝ uᵝ⟩, the distinction between protruded and compressed holds for the semivowels and as well as labialization. In Akan, for example, the is compressed, as are labio-palatalized consonants as in Twi Twi and adwuma work, whereas, in Japanese, the /w/ is compressed rather than protruded, paralleling the Japanese /u/. The distinction applies marginally to other consonants, some vowels transcribed with rounded IPA letters may not be rounded at all. An example is /ɒ/, which in English has very little if any rounding of the lips, the throaty sound of English /ɒ/ is instead accomplished with sulcalization, a furrowing of the back of the tongue also found in non-rhotic /ɜː/. It is possible to mimic the effect of rounded vowels by narrowing the cheeks, so-called cheek rounding. The technique is used by ventriloquists to mask the visible rounding of back vowels like and it is not clear if it is used by languages with rounded vowels that do not use visible rounding. Protruded rounding is the equivalent of consonantal labialization

Southern American English
–
Southern American English or Southern U. S. English is a collection of related American English dialects spoken throughout the Southern United States, though increasingly in more rural areas, commonly in the United States, the dialects are together simply referred to as Southern. Other, much more recent ethno-linguistic terms within American linguistics include Southern White Vernacular English, with this younger and more unified pronunciation system, Southern American English now comprises the largest American regional accent group by number of speakers. As of 2006, its Southern accent is strongly reported throughout the U. S. Louis in eastern Missouri, African American Vernacular English has many common points with Southern English dialects due to the strong historical ties of African Americans to the region. Southern American English dialects can also be found in southern parts of Missouri, Maryland, Delaware. Upheavals such as the Great Depression, the Dust Bowl and World War II caused mass migrations of those, the South proper as a present-day dialect region generally includes all of these pronunciation features below, which are popularly recognized in the United States as a Southern accent. However, there is still actually wide variation in Southern speech regarding potential differences based on factors like a speakers exact sub-region, age, ethnicity, Stage 1 is now complete for a majority of Southern dialects. Some traditional East Coast Southern accents do not exhibit this Stage 1 glide deletion, particularly in Charleston, SC and possibly Atlanta and Savannah, an example is that, to other English speakers, the Southern pronunciation of yap sounds something like yeah-up. At the same time, the pushing of /æ/ into the vicinity of /ɛ/, forces /ɛ/ itself into a higher and fronter position, /ɛ/ also often acquires an in-glide, thus. An example is that, to other English speakers, the Southern pronunciation of yep sounds something like yay-up, Stage 2 is most common in heavily stressed syllables. Southern accents originating from cities that formerly had the greatest influence, Stage 3, By the same pushing and pulling domino effects described above, /ɪ/ and /i/ follow suit by both possibly becoming diphthongs whose nuclei switch positions. /ɪ/ may be pushed into a diphthong with a raised beginning, an example is that, to other English speakers, the Southern pronunciation of fin sounds something like fee-in, while meal sounds something like mih-eel. Like the other stages of the Southern shift, Stage 3 is most common in stressed syllables. This short front vowel gliding phenomenon is recognized as the Southern drawl. This phenomenon is on the decline, being most typical of Southern speakers born before 1960, unstressed, word-final /ŋ/ →, The phoneme /ŋ/ in an unstressed syllable at the end of a word fronts to, so that singing /ˈsɪŋɪŋ/ is sometimes written phonetically as singin. This is common in vernacular English dialects around the world, lacking or transitioning cot–caught merger, The historical distinction between the two vowels sounds /ɔː/ and /ɒ/, in words like caught and cot or stalk and stock is mainly preserved. In much of the South during the 1900s, there was a trend to lower the vowel found in words like stalk and caught, often with an upglide, so that the most common result today is the gliding vowel. However, the merger is becoming increasingly common throughout the United States, thus affecting Southern dialects

Scottish English
–
Scottish English refers to the varieties of English spoken in Scotland. The main, formal variety is called Scottish Standard English or Standard Scottish English, Scottish Standard English may be defined as the characteristic speech of the professional class and the accepted norm in schools. IETF language tag for Scottish Standard English is en-Scotland, Scottish Standard English is at one end of a bipolar linguistic continuum, with focused broad Scots at the other. Scottish English may be influenced to varying degrees by Scots, many Scots speakers separate Scots and Scottish English as different registers depending on social circumstances. Some speakers code switch clearly from one to the other while others style shift in a less predictable, generally there is a shift to Scottish English in formal situations or with individuals of a higher social status. Scottish English results from contact between Scots and the Standard English of England after the 17th century. Furthermore, the process was influenced by interdialectal forms, hypercorrections. Convention traces the influence of the English of England upon Scots to the 16th-century Reformation, printing arrived in London in 1476, but the first printing press was not introduced to Scotland for another 30 years. Texts such as the Geneva Bible, printed in English, were distributed in Scotland in order to spread Protestant doctrine. King James VI of Scotland became King James I of England in 1603, since England was the larger and richer of the two Kingdoms, James moved his court to London in England. The poets of the court therefore moved south and began adapting the language, to this event McClure attributes he sudden and total eclipse of Scots as a literary language. The continuing absence of a Scots translation of the Bible meant that the translation of King James into English was used in worship in both countries, the Acts of Union 1707 amalgamated the Scottish and English Parliaments. However the church, educational and legal structures remained separate and this leads to important professional distinctions in the definitions of some words and terms. There are therefore words with precise definitions in Scottish English which have no place in English English or have a different definition. The speech of the classes in Scotland tends to conform to the grammatical norms of the written standard. Highland English is slightly different from the variety spoken in the Lowlands in that it is more phonologically, grammatically, similarly, the English spoken in the North-East of Scotland tends to follow the phonology and grammar of Doric. Although other dialects have merged non-intervocalic /ɛ/, /ɪ/, /ʌ/ before /r/, many varieties contrast /o/ and /ɔ/ before /r/ so that hoarse and horse are pronounced differently. /or/ and /ur/ are contrasted so that shore and sure are pronounced differently, as are pour, an epenthetic vowel may occur between /r/ and /l/ so that girl and world are two-syllable words for some speakers

Phonation
–
The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration and this is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Voiceless and supra-glottal phonations are included under this definition, the phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufficiently large, the vocal folds start to oscillate, the minimum pressure drop required to achieve phonation is called the phonation threshold pressure, and for humans with normal vocal folds, it is approximately 2–3 cm H2O. The motion of the vocal folds during oscillation is mostly lateral, however, there is almost no motion along the length of the vocal folds. The oscillation of the vocal folds serves to modulate the pressure and flow of the air through the larynx, the sound that the larynx produces is a harmonic series. In other words, it consists of a fundamental tone accompanied by harmonic overtones, in linguistics, a phone is called voiceless if there is no phonation during its occurrence. In speech, voiceless phones are associated with folds that are elongated, highly tensed. Fundamental frequency, the main acoustic cue for the percept pitch, large scale changes are accomplished by increasing the tension in the vocal folds through contraction of the cricothyroid muscle. Variation in fundamental frequency is used linguistically to produce intonation and tone, There are currently two main theories as to how vibration of the vocal folds is initiated, the myoelastic theory and the aerodynamic theory. These two theories are not in contention with one another and it is possible that both theories are true and operating simultaneously to initiate and maintain vibration. A third theory, the theory, was in considerable vogue in the 1950s. Pressure builds up again until the cords are pushed apart. The rate at which the open and close—the number of cycles per second—determines the pitch of the phonation. The aerodynamic theory is based on the Bernoulli energy law in fluids, the push occurs during glottal opening, when the glottis is convergent, whereas the pull occurs during glottal closing, when the glottis is divergent. Such an effect causes a transfer of energy from the airflow to the fold tissues which overcomes losses by dissipation. The amount of pressure needed to begin phonation is defined by Titze as the oscillation threshold pressure. During glottal closure, the air flow is cut off until breath pressure pushes the folds apart and this theory states that the frequency of the vocal fold vibration is determined by the chronaxie of the recurrent nerve, and not by breath pressure or muscular tension

International Phonetic Alphabet
–
The International Phonetic Alphabet is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association as a representation of the sounds of spoken language. The IPA is used by lexicographers, foreign students and teachers, linguists, speech-language pathologists, singers, actors, constructed language creators. The IPA is designed to represent only those qualities of speech that are part of language, phones, phonemes, intonation. IPA symbols are composed of one or more elements of two types, letters and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a letter, or with a letter plus diacritics. Often, slashes are used to signal broad or phonemic transcription, thus, /t/ is less specific than, occasionally letters or diacritics are added, removed, or modified by the International Phonetic Association. As of the most recent change in 2005, there are 107 letters,52 diacritics and these are shown in the current IPA chart, posted below in this article and at the website of the IPA. In 1886, a group of French and British language teachers, led by the French linguist Paul Passy, for example, the sound was originally represented with the letter ⟨c⟩ in English, but with the digraph ⟨ch⟩ in French. However, in 1888, the alphabet was revised so as to be uniform across languages, the idea of making the IPA was first suggested by Otto Jespersen in a letter to Paul Passy. It was developed by Alexander John Ellis, Henry Sweet, Daniel Jones, since its creation, the IPA has undergone a number of revisions. After major revisions and expansions in 1900 and 1932, the IPA remained unchanged until the International Phonetic Association Kiel Convention in 1989, a minor revision took place in 1993 with the addition of four letters for mid central vowels and the removal of letters for voiceless implosives. The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap, apart from the addition and removal of symbols, changes to the IPA have consisted largely in renaming symbols and categories and in modifying typefaces. Extensions to the International Phonetic Alphabet for speech pathology were created in 1990, the general principle of the IPA is to provide one letter for each distinctive sound, although this practice is not followed if the sound itself is complex. There are no letters that have context-dependent sound values, as do hard, finally, the IPA does not usually have separate letters for two sounds if no known language makes a distinction between them, a property known as selectiveness. These are organized into a chart, the chart displayed here is the chart as posted at the website of the IPA. The letters chosen for the IPA are meant to harmonize with the Latin alphabet, for this reason, most letters are either Latin or Greek, or modifications thereof. Some letters are neither, for example, the letter denoting the glottal stop, ⟨ʔ⟩, has the form of a question mark

Tuscan dialect
–
Tuscan is an Italo-Dalmatian variety mainly spoken in Tuscany, Italy. It would later become the language of all the Italian states. Tuscan is a complex composed of many local variants, with minor differences among them. The main subdivision is between Northern Tuscan dialects and Southern Tuscan dialects, the Northern Tuscan dialects are, Fiorentino, the main dialect of Florence, Chianti and the Mugello region, also spoken in Prato and along the river Arno as far as the city of Fucecchio. Pistoiese, spoken in the city of Pistoia and nearest zones, pesciatino or Valdinievolese, spoken in the Valdinievole zone, in the cities of Pescia and Montecatini Terme. Lucchese, spoken in Lucca and nearby hills, versiliese, spoken in the historical area of Versilia. Viareggino, spoken in Viareggio and vicinity, pisano-Livornese, spoken in Pisa and in Livorno and the vicinity, and along the southern coast as far as the city of Piombino. The Southern Tuscan dialects are, Aretino-Chianaiolo, spoken in Arezzo, senese, spoken in the city and province of Siena. Grossetano, spoken in the city and province of Grosseto, Corsican and Gallurese, Corsican on the island of Corsica, and its variety spoken in Sardinia, are classified by scholars as a direct offshoot from medieval Tuscan. Excluding the inhabitants of Province of Massa and Carrara, who speak an Emilian variety of a Gallo-Italic language, the Tuscan dialect as a whole has certain defining features, with subdialects that are distinguished by minor details. The Tuscan gorgia affects the voiceless stop consonants /k/ /t/ and /p/, between vowels, the voiced post-alveolar affricate consonant is realized as voiced post-alveolar fricative, /dʒ/ →. This phenomenon is evident in daily speech, the phrase la gente, the people, in standard Italian is pronounced. Similarly, the voiceless affricate is pronounced as a voiceless post-alveolar fricative between two vowels, /tʃ/ →. The sequence /la ˈtʃena/ la cena, the dinner, in standard Italian is pronounced, as a result of this weakening rule, there are a few minimal pairs distinguished only by length of the voiceless fricative. A less common phenomenon is the transformation of voiceless s or voiceless alveolar fricative /s/ into the voiceless alveolar affricate when preceded by /r/, /l/. For example, il sole, pronounced in standard Italian as, however, since assimilation of the final consonant of the article to the following consonant tends to occur in exactly such cases the actual pronunciation will be usually. Affrication of /s/ can more commonly be heard word-internally, as in falso /ˈfalso/ → and this is a common phenomenon in Central Italy, but it is not exclusive to that area, for example it also happens in Switzerland. There are two Tuscan historical outcomes of Latin ŏ in stressed open syllables, passing first through a stage, the vowel then develops as a diphthong /wɔ/

Received Pronunciation
–
Peter Trudgill estimated in 1974 that 3% of people in Britain were RP speakers, but this rough estimate has been questioned by the phonetician J. Windsor Lewis. Since the 1960s, a greater permissiveness towards regional English varieties has taken hold in education, an individual using RP will typically speak Standard English, although the converse or inverse is not necessarily true. The standard language may be pronounced with an accent and the contrapositive is usually correct. It is very unlikely that someone speaking RP would use it to speak a regional dialect, the introduction of the term Received Pronunciation is usually credited to Daniel Jones. However, the term had actually been used earlier by Alexander Ellis in 1869 and P. S. Du Ponceau in 1818 According to Fowlers Modern English Usage. The word received conveys its meaning of accepted or approved. RP is often believed to be based on the accents of southern England and this was the most populated and most prosperous area of England during the 14th and 15th centuries. By the end of the 15th century, Standard English was established in the City of London, some linguists have used the term RP while expressing reservations about its suitability. Other writers have used the name BBC Pronunciation. He used the term General British in his 1970s publication of A Concise Pronouncing Dictionary of American and British English, Received Pronunciation has sometimes been called Oxford English, as it used to be the accent of most members of the University of Oxford. The Handbook of the International Phonetic Association uses the name Standard Southern British, page 4 reads, Standard Southern British is the modern equivalent of what has been called Received Pronunciation. It is an accent of the south east of England which operates as a prestige norm there and in parts of the British Isles. Faced with the difficulty of defining RP, many writers have tried to distinguish between different sub-varieties, later editions use the terms General, Refined and Regional. Wells refers to mainstream RP and U-RP, he suggests that Gimsons categories of Conservative and Advanced RP referred to the U-RP of the old, however, Wells stated, It is difficult to separate stereotype from reality with U-RP. Upton distinguishes between RP, Traditional RP, and an older version which he identifies with Cruttendens Refined RP. An article on the website of the British Library refers to Conservative, Mainstream, the modern style of RP is an accent often taught to non-native speakers learning British English. Non-RP Britons abroad may modify their pronunciation to something closer to Received Pronunciation to be understood by people unfamiliar with the diversity of British accents. They may also modify their vocabulary and grammar to be closer to those of Standard English for the same reason
