Hanyu Pinyin

Welcome to our website. It is generaly simplier version of wikipedia. You will find there selected articles. Enjoy!

Pinyin (Simplified / Traditional Chinese:拼音), or more formally Hanyu Pinyin (汉语拼音 / 漢語拼音), is currently the most commonly used romanization system for Standard Mandarin. Hànyǔ (汉语 / 漢語) means the Chinese language, and Pīnyīn (拼音) means "phonetics", or more literally, "spelling sound" or "spelled sound". The system is now used in mainland China, Hong Kong, Macau, parts of Taiwan, Malaysia and Singapore to teach Mandarin Chinese and internationally to teach Mandarin as a second language. It is also often used to spell Chinese names in foreign publications and can be used to enter Chinese characters (hanzi) on computers and cellphones.

The romanization system was developed by a government committee in the People's Republic of China (PRC), and approved by the Chinese government on February 11, 1958. The International Organization for Standardization adopted pinyin as the international standard in 1982, and since then it has been adopted by many other organizations. This romanization system also became the national standard in the Republic of China (ROC, commonly known as Taiwan) on January 1, 2009.

History

In 1954, the Ministry of Education of the People's Republic of China (PRC) created a Committee for the Reform of the Chinese Written Language. This committee developed Hanyu pinyin based upon several preexisting systems: (Gwoyeu Romatzyh of 1928, Latinxua Sin Wenz of 1931, and the diacritic markings from zhuyin). The main force behind pinyin was Zhou Youguang. Zhou was working in a New York bank when he decided to return to China to help rebuild the country after establishment of the PRC in 1949. He became an economics professor in Shanghai and was assigned to help the development of a new romanization system.

A first draft was published on February 12, 1956. The first edition of Hanyu pinyin was approved and adopted at the Fifth Session of the 1st National People's Congress on February 11, 1958. It was then introduced to primary schools as a way to teach Standard Mandarin pronunciation and used to improve the literacy rate among adults. In 2001, the Chinese Government issued the National Common Language Law, providing a legal basis for applying pinyin.

Usage

Pinyin superseded older romanization systems such as Wade-Giles (1859; modified 1892) and Chinese Postal Map Romanization, and replaced zhuyin as the method of Chinese phonetic instruction in mainland China. The International Organization for Standardization (ISO) adopted pinyin as the standard romanization for modern Chinese in 1982 (ISO 7098:1982, superseded by ISO 7098:1991); the United Nations followed suit in 1986. It has also been accepted by the government of Singapore, the United States' Library of Congress, the American Library Association, and many other international institutions.

The spelling of Chinese geographical or personal names in pinyin has become the most common way to transcribe them in English. Pinyin has also become a useful tool for entering Chinese text into computers.

Posters and slogans in and around Chinese schools often have each character annotated with its Standard Mandarin reading in Pinyin

Chinese families who speak Mandarin as a mother tongue use pinyin to help children associate characters with spoken words which they already know. Chinese families who speak some other language as their mother tongue use the system to teach children Mandarin pronunciation when they learn vocabulary in elementary school.

Since 1958, Pinyin has been actively used in adult education as well, making it easier for formerly illiterate people to continue with self-study after a short period of Pinyin literacy instruction.

Pinyin has become a tool for many foreigners to learn the Mandarin pronunciation, and is used to explain the grammar and spoken Mandarin together with hanzi. Books containing both Chinese characters and pinyin are often used by foreign learners of Chinese; pinyin's role in teaching pronunciation to foreigners and children is similar in some respects to furigana-based books (with hiragana letters written above or next to kanji) in Japanese or fully vocalised texts in Arabic ("vocalised Arabic").

The tone-marking diacritics are commonly omitted in popular news stories and even in scholarly works. An unfortunate effect of this is the ambiguity that results about which Chinese characters are being represented.

Overview

In Yiling, Yichang, Hubei, text on road signs appears both in Hanzi and in Pinyin

The correspondence between Roman letter and sound in the system is sometimes idiosyncratic, though not necessarily more so than the way the Roman alphabet is employed in other languages. For example, the aspiration distinction between b, d, g and p, t, k is similar to that of English, but not to that of French. Z and c also have that distinction; however, they are pronounced as [ts], as in German and Italian, which do not have that distinction. From s, z, c come the digraphs sh, zh, ch by analogy with English sh, ch. Although this introduces the novel combination zh, it is internally consistent in how the two series are related, and reminds the trained reader that many Chinese pronounce sh, zh, ch as s, z, c. In the x, j, q series, the Pinyin use of x is similar to its use in Portuguese, Galician, Catalan, Basque and Maltese; and the Pinyin q is akin to its value in Albanian; both Pinyin and Albanian pronunciations may sound similar to the ch to the untrained ear. Pinyin vowels are pronounced in a similar way to vowels in Romance languages. More information on the pronunciation of all pinyin letters in terms of English approximations is given further below.

The pronunciation and spelling of Chinese words are generally given in terms of initials and finals, which represent the segmental phonemic portion of the language, rather than letter by letter. Initials are initial consonants, while finals are all possible combinations of medials (semivowels coming before the vowel), the nucleus vowel, and coda (final vowel or consonant).

Initials and finals

Unlike in European languages, initials (simplified Chinese: 声母; traditional Chinese: 聲母; pinyin: shēngmǔ) and finals (simplified Chinese: 韵母; traditional Chinese: 韻母; pinyin: yùnmǔ)—and not consonants and vowels—are the fundamental elements in pinyin (and most other phonetic systems used to describe the Han language). Nearly each Chinese syllable can be spelled with exactly one initial followed by one final, except in the special syllable er and when a trailing -r is considered part of a syllable (see below). The latter case, though a common practice in some sub-dialects, is rarely used in official publications. One exception is the city Harbin (simplified Chinese: 哈尔滨; traditional Chinese: 哈爾濱), which is from the Manchu language originally.

Even though most initials contain a consonant, finals are not simple vowels, especially in compound finals (simplified Chinese: 复韵母; traditional Chinese: 複韻母; pinyin: fuyunmu), i.e., when one "final" is placed in front of another one. For example, [i] and [u] are pronounced with such tight openings that some native Chinese speakers (especially when singing or on stage) pronounce yī (simplified Chinese: 衣; traditional Chinese: 衣, clothes, officially pronounced /i/) as /ji/, wéi (simplified Chinese: 围; traditional Chinese: 圍, to enclose, officially as /uei/) as /wei/ or /wuei/. The concepts of consonant and vowel are not incorporated in pinyin or its predecessors; there is no list of consonants or vowels.

Initials

In each cell below, the first line indicates the IPA, the second indicates pinyin.

¹ /ɻ/ may phonetically be /ʐ/ (a voiced retroflex fricative). This pronunciation varies among different speakers, and is not two different phonemes.
² the letters "w" and "y" are not included in the table of initials in the official pinyin system. They are an orthographic convention for the medials "i", "u" and "ü" when no initial is present. When "i", "u" or "ü" are finals and no initial is present, they are spelled "yi", "wu", and "yu", respectively.
³ "y" is pronounced [ɥ] before "u".

Conventional order (excluding w and y), derived from the zhuyin system, is:

Finals

In each cell below, the first line indicates IPA, the second indicates pinyin for a standalone (no-initial) form, and the third indicates pinyin for a combination with an initial. Other than finals modified by an -r, which are omitted, the following is an exhaustive table of all possible finals.¹

The only syllable-final consonants in standard Mandarin are -n and -ng, and -r, which is attached as a grammatical suffix. Chinese syllables ending with any other consonant is either from a non-Mandarin language (southern Chinese languages such as Cantonese, or minority languages of China), or it indicates the use of a non-pinyin Romanization system (where final consonants may be used to indicate tones).

¹ [ɑɻ] (而, 二, etc.) is written er. For other finals formed by the suffix -r, pinyin does not use special orthography; one simply appends -r to the final that it is added to, without regard for any sound changes that may take place along the way. For information on sound changes related to final -r, please see Standard Mandarin.
² "ü" is written as "u" after j, q, x, or y.
³ "uo" is written as "o" after b, p, m, or f.
⁴ It is pronounced [ʊŋ] when it follows an initial, and pinyin reflects this difference.

Technically, i, u, ü without a following vowel are finals, not medials, and therefore take the tone marks, but they are more concisely displayed as above. In addition, ê [ɛ] (欸, 誒) and syllabic nasals m (呒, 呣), n (嗯, 唔), ng (嗯, 𠮾) are used as interjections.

Rules given in terms of English pronunciation

All rules given here in terms of English pronunciation are approximate, as several of these sounds do not correspond directly to sounds in English.

Pronunciation of initials

* Note on w, y, and the apostrophe

Y and w are equivalent to the semivowel medials i, u, and ü (see below). They are spelled differently when there is no initial consonant in order to mark a new syllable: fanguan is fan-guan, while fangwan is fang-wan (and equivalent to *fang-uan). With this convention, an apostrophe only needs to be used to mark an initial a, e, or o: Xi'an (two syllables: [ɕi.an]) vs. xian (one syllable: [ɕi̯ɛn]). In addition, y and w are added to fully vocalic i, u, and ü when these occur without an initial consonant, so that they are written yi, wu, and yu. Some Mandarin speakers do pronounce a [j] or [w] sound at the beginning of such words—that is, yi [i] or [ji], wu [u] or [wu], yu [y] or [ɥy],—so this is an intuitive convention. See below for a few finals which are abbreviated after a consonant plus w/u or y/i medial: wen → C+un, wei → C+ui, weng → C+ong, and you → C+iu.

Pronunciation of finals

The following is a list of finals in Standard Mandarin, excepting most of those ending with a -r.

To find a given final:

1. Remove the initial consonant. Zh, ch, and sh count as initial consonants.
2. Change initial w to u and initial y to i. For weng, wei, you, look under ong, ui, iu.
3. For u after j, q, x, or y, look under ü.

Orthography

Letters

Pinyin differs from other romanizations in several aspects, such as the following:

• Syllables starting with u are written as w in place of u (e.g. ueng is written as weng). Standalone u is written as wu.
• Syllables starting with i are written as y in place of i (e.g. ian is written as yan). Standalone i is written as yi.
• Syllables starting with ü are written as yu in place of ü (e.g. üe is written as yue).
• ü is written as u when there is no ambiguity (such as ju, qu, and xu), but written as ü when there are corresponding u syllables (such as lü and nü). In such situations where there are corresponding u syllables, it is often replaced with v on a computer, making it easier to type on a standard keyboard.
• When preceded by a consonant, iou, uei, and uen are simplified as iu, ui, and un (which do not represent the actual pronunciation).
• As in zhuyin, what are actually pronounced as buo, puo, muo, and fuo are given a separate representation: bo, po, mo, and fo.
• The apostrophe (') is often used before a, o, and e to separate syllables in a word where ambiguity could arise, as in Xi'an, which consists of the two syllables xi ("西") and an ("安") as opposed to xian for such words as "先". (This ambiguity does not occur when tone marks are used: The two tone marks in "Xīān" unambiguously show that the word consists of two syllables. However, even with tone marks, the city is usually spelled with an apostrophe as "Xī'ān".)
• Eh alone is written as ê; elsewhere as e. Schwa is always written as e.
• zh, ch, and sh can be abbreviated as ẑ, ĉ, and ŝ (z, c, s with a circumflex). However, the shorthands are rarely used due to difficulty of entering them on computers.
• ng has the uncommon shorthand of ŋ.
• The letter v is unused （except in spelling foreign languages, languages of minority nationalities, and some dialects), despite a conscious effort to distribute letters more evenly than in Western languages. However, sometimes, for ease of typing into a computer, the v is used to replace a ü.

Most of the above are used to avoid ambiguity when writing words of more than one syllable in pinyin. For example uenian is written as wenyan because it is not clear which syllables make up uenian; uen-ian, uen-i-an and u-en-i-an are all possible combinations whereas wenyan is unambiguous because we, nya, etc. do not exist in pinyin. See the pinyin table article for a summary of possible pinyin syllables (not including tones).

Capitalization and word formation

Although Chinese characters represent single syllables, Mandarin Chinese is a polysyllabic language. Spacing in pinyin is based on whole words, not single syllables. However, there are often ambiguities in partitioning a word. Orthographic rules were put into effect in 1988 by the National Educational Commission (国家教育委员会, pinyin: Guójiā Jiàoyù Wěiyuánhuì ) and the National Language Commission (国家语言文字工作委员会, pinyin: Guójiā Yǔyán Wénzì Gōngzuò Wěiyuánhuì).

Tones

Relative pitch changes of the four tones

The pinyin system also uses diacritics to mark the four tones of Mandarin. The diacritic is placed over the letter that represents the syllable nucleus, unless that letter is missing (see below). Many books printed in China use a mix of fonts, with vowels and tone marks rendered in a different font than the surrounding text, tending to give such pinyin texts a typographically ungainly appearance. This style, most likely rooted in early technical limitations, has led many to believe that pinyin's rules call for this practice and also for the use of a Latin alpha ("ɑ") rather than the standard style of the letter ("a") found in most fonts. The official rules of Hanyu Pinyin, however, specify no such practice.

1. The first tone (Flat or High Level Tone) is represented by a macron (ˉ) added to the pinyin vowel:

   
   ā (ɑ̄) ē ī ō ū ǖ Ā Ē Ī Ō Ū Ǖ

2. The second tone (Rising or High-Rising Tone) is denoted by an acute accent (ˊ):

   
   á (ɑ́) é í ó ú ǘ Á É Í Ó Ú Ǘ

3. The third tone (Falling-Rising or Low Tone) is marked by a caron/háček (ˇ). It is not the rounded breve (˘), though a breve is sometimes substituted due to font limitations.

   
   ǎ (ɑ̌) ě ǐ ǒ ǔ ǚ Ǎ Ě Ǐ Ǒ Ǔ Ǚ

4. The fourth tone (Falling or High-Falling Tone) is represented by a grave accent (ˋ):

   
   à (ɑ̀) è ì ò ù ǜ À È Ì Ò Ù Ǜ

5. The fifth tone (Neutral Tone) is represented by a normal vowel without any accent mark:

   
   a (ɑ) e i o u ü A E I O U Ü

(In some cases, this is also written with a dot before the syllable; for example, ·ma.)

These tone marks normally are only used in Mandarin textbooks or in foreign learning texts, but they are essential for correct pronunciation of Mandarin syllables, as exemplified by the following classic example of five characters whose pronunciations differ only in their tones:

The words are "mother", "hemp", "horse", "scold" and a question particle, respectively.

Numerals in place of tone marks

Before the advent of computers, many typewriter fonts did not contain vowels with macron or caron diacritics. Tones were thus represented by placing a tone number at the end of individual syllables. For example, tóng is written tong2. The number used for each tone is as the order listed above, except the neutral tone, which is either not numbered, or given the number 0 or 5, e.g. ma5 for 吗/嗎, an interrogative marker.

Rules for placing the tone mark

Pinyin tone marks appear primarily above the nucleus of the syllable, for example as in kuài, where k is the initial, u the medial, a the nucleus, and i the coda. The exception is syllabic nasals like m, where the nucleus of the syllable is a consonant, the diacritic will be carried by a vowel.

When the nucleus is /ə/ (written e or o), and there is both a medial and a coda, the nucleus may be dropped from writing. When the coda is a consonant n or ng, the only vowel left is the medial i, u, or ü, and so this takes the diacritic. However, when the coda is a vowel, it is the coda rather than the medial which takes the diacritic. This occurs with syllables ending in -ui, from wei, and in -iu, from you (wèi → -uì; yòu → -iù). That is, finals have priority, as long as they are vowels: if not, the medial takes the diacritic.

An algorithm to find the correct vowel letter (when there is more than one) is as follows:

1. If there is an "a" or an "e", it will take the tone mark.
2. If there is an "ou", then the "o" takes the tone mark.
3. Otherwise, the second vowel takes the tone mark.

Worded differently,

1. If there is an "a", "e", or "o", it will take the tone mark; in the case of "ao", the mark goes on the "a".
2. Otherwise, the vowels are "-iu" or "-ui", in which case the second vowel takes the tone mark.

If the tone is written over an i, the dot above the i is omitted, as in yī.

Using tone colors

In addition to tone number and mark, tone color has been suggested as a visual aid for learning. Although there are no formal standards, the de facto standard has been to use red (tone 1), orange (tone 2), green (tone 3),blue (tone 4) and black (tone 5).

The character "ü"

An umlaut is placed over the letter u when it occurs after the initials l and n in order to represent the sound [y]. This is necessary in order to distinguish the front high rounded vowel in lü (e.g. 驴/驢 donkey) from the back high rounded vowel in lu (e.g. 炉/爐 oven). Tonal markers are added on top of the trema, as in lǘ.

However, the ü is not used in other contexts where it represents a front high rounded vowel, namely after the letters j, q, x and y. For example, the sound of the word 鱼/魚 (fish) is transcribed in pinyin simply as yú, not as yǘ. This practice is opposed to Wade-Giles, which always uses ü, and Tongyong pinyin, which always uses yu. Whereas Wade-Giles needs to use the trema to distinguish between chü (pinyin ju) and chu (pinyin zhu), this ambiguity cannot arise with pinyin, so the more convenient form ju is used instead of jü. Genuine ambiguities only happen with nu/nü and lu/lü, which are then distinguished by a trema (diacritic).

Many fonts or output methods do not support a trema for ü or cannot place tone marks on top of ü. Likewise, using ü in input methods is difficult because it is not present as a simple key on many keyboard layouts. For these reasons v is sometimes used instead by convention. For example, it is common for cellphones to use v instead of ü. Additionally, some stores in China use v instead of ü in the transliteration of their names. Occasionally, uu (double u), u: (u followed by a colon) or U (capital u) is used in its place.

Although nüe written as nue, and lüe written as lue are not ambiguous, nue or lue are not correct according the rules; nüe and lüe should be used instead. However, some Chinese input methods (e.g. Microsoft Pinyin IME) support both nve/lve (typing v for ü) and nue/lue.

Comparison chart

Pinyin in Taiwan

Taiwan (Republic of China) adopted Tongyong pinyin, a modification of Hanyu pinyin, as the official romanization system on the national level between October 2002 and January 2009, when it switched to Hanyu pinyin. The romanization system in use became a political issue, much of it centered on issues of national identity, with proponents of Chinese reunification favoring Hanyu pinyin, the official romanization system used in the People's Republic of China as well as internationally, and proponents of Taiwanese independence favoring the use of the locally developed Tongyong pinyin.

The adoption of Tongyong pinyin was an administrative order that could be overruled by local governments. Some localities with governments controlled by the Kuomintang (KMT), most notably Taipei, Hsinchu, and Kinmen County, overrode the order and converted to Hanyu pinyin before the January 1, 2009 national-level switch, though with a slightly different capitalization convention than mainland China. Most areas of Taiwan adopted Tongyong Pinyin, consistent with the national policy. As a result, the use of romanization on signage in Taiwan has been inconsistent. Many signs display Tongyong pinyin but some display Hanyu pinyin, and others still display old Wade-Giles or MPS2 signage. This has led to odd situations: for instance, in Taipei there were inconsistent romanizations shown in freeway directions: freeway signs, under the control of the central government, used Tongyong, while surface street signs, under the control of the city government, used, and still use, Hanyu Pinyin.

The adoption of Hanyu pinyin, intended by the government to be a truly national standard in Taiwan, is viewed as an international system. Still, some place names in Taiwan will retain older spellings because of their familiarity. Personal names on passports will honor the choices of Taiwanese citizens, who often prefer the Wade-Giles romanisation of their personal names. Transition to Hanyu pinyin is necessarily gradual, as questions remain about the ability of the national government to enforce the standard island-wide.

Primary education in Taiwan continues to teach pronunciation using zhuyin (MPS or Mandarin Phonetic Symbols).

Other languages

Pinyin-like systems have been devised for other variants of Chinese. Guangdong Romanization is a set of romanizations devised by the government of Guangdong province for Cantonese, Teochew, Hakka (Moiyen dialect), and Hainanese. All of these are designed to use Latin letters in a similar way to pinyin.

In addition, in accordance to the Regulation of Phonetic Transcription in Hanyu Pinyin Letters of Place Names in Minority Nationality Languages (少数民族语地名汉语拼音字母音译转写法) promulgated in 1976, place names in non-Han languages like Mongol, Uyghur, and Tibetan are also officially transcribed using pinyin. The pinyin letters (26 Roman letters, ü, ê) are used to approximate the non-Han language in question as closely as possible. This results in spellings that are different from both the customary spelling of the place name, and the pinyin spelling of the name in Chinese:

Comparison with other orthographies

Pinyin is now used by foreign students learning Chinese as a second language.

Pinyin assigns some Roman letters phonological values which are quite different from that of most languages.

Pinyin is purely a representation of the sounds of Mandarin, therefore it lacks the semantic cues that Chinese characters can provide. It is also unsuitable for transcribing some Chinese spoken languages other than Mandarin.

Simple computer systems, able to display only 7-bit ASCII text (essentially the 26 Latin letters, 10 digits and punctuation marks), long provided a convincing argument in favor of pinyin over hanzi. Today, however, most computer systems are able to display characters from Chinese and many other writing systems as well, and have them entered with a Latin keyboard using an input method editor. Alternatively, some PDAs, tablet PCs and digitizing tablets allow users to input characters directly by writing with a stylus.
