[[File:Taiwan_Strait.png|thumb|300px|Map of the [[Taiwan Strait]], featuring names using Wade–Giles in Taiwan versus those using pinyin in mainland China]]

'''Wade–Giles''' ({{IPAc-en|w|eɪ|d|_|dʒ|aɪ|l|z}} {{respell|wayd|_|jylze}}) is a [[Romanization of Chinese|romanization system]] for [[Standard Chinese|Mandarin Chinese]]. It developed from the system produced by [[Thomas Francis Wade]] during the mid-19th century, and was given completed form with [[Herbert Giles]]'s ''[[A Chinese–English Dictionary]]'' (1892).

The romanization systems in common use until the late 19th century were based on the [[Nanjing dialect]], but Wade–Giles was based on the [[Beijing dialect]] and was the system of transcription familiar in the English-speaking world for most of the 20th century. Both of these kinds of transcription were used in [[postal romanization]]s (romanized place-names standardized for postal uses). In [[mainland China]], Wade–Giles has been mostly replaced by [[Hanyu Pinyin]], which was officially adopted in 1958, with exceptions for the romanized forms of some of the most commonly used names of locations and persons, and other proper nouns. The romanized name for most locations, persons and other proper nouns in Taiwan is based on the Wade–Giles derived romanized form, for example [[Kaohsiung]], the [[Matsu Islands]] and [[Chiang Ching-kuo]].

==History==
Wade–Giles was developed by [[Thomas Francis Wade]], a scholar of Chinese and a British ambassador in China who was the first professor of Chinese at the [[University of Cambridge]]. Wade published ''{{lang|zh-Latn-wadegile|Yü-yen Tzŭ-erh Chi}}'' ({{zhi|first=t|t=語言自邇集|s=语言自迩集}})<ref>{{Cite book |last=Wade |first=Thomas Francis |url=https://books.google.com/books?id=Fu0aAAAAYAAJ |title=Yü-yen Tzŭ-erh Chi: A Progressive Course Designed to Assist the Student of Colloquial Chinese, As Spoken in the Capital and the Metropolitan Department |publisher=Trübner |year=1867 |location=London |language=zh}}</ref>  in 1867, the first textbook on the [[Beijing dialect]] of [[Mandarin Chinese|Mandarin]] in English,<ref name="Kaske2008">{{Cite book |last=Kaske |first=Elisabeth |url=https://books.google.com/books?id=okhrBBmnHVQC |title=The Politics of Language in Chinese Education: 1895–1919 |publisher=Brill |year=2008 |isbn=978-9-004-16367-6 |page=68}}</ref> which became the basis for the system later known as Wade–Giles. The system, designed to transcribe Chinese terms for Chinese specialists, was further refined in 1892 by [[Herbert Giles]] (in ''[[A Chinese–English Dictionary]]''), a British diplomat in China, and his son [[Lionel Giles]],{{citation needed|date=September 2016}} a curator at the British Museum.<ref>{{Cite web |title=Chinese Language Transliteration Systems – Wade–Giles |url=http://polaris.gseis.ucla.edu/skozerow/wadegiles.htm |archive-url=https://web.archive.org/web/20070128065433/http://polaris.gseis.ucla.edu/skozerow/wadegiles.htm |archive-date=2007-01-28 |access-date=2007-08-04 |publisher=UCLA film and television archive}} (Web archive)</ref>

Taiwan used Wade–Giles for decades as the de facto standard, co-existing with several official romanizations in succession, namely, [[Gwoyeu Romatzyh]] (1928), [[Mandarin Phonetic Symbols II]] (1986), and [[Tongyong Pinyin]] (2000). The [[Kuomintang]] (KMT) has previously promoted pinyin with [[Ma Ying-jeou]]'s successful presidential bid in 2008 and in a number of cities with Kuomintang mayors.{{Citation needed|date=November 2024}} However, the [[Tsai Ing-wen]] administration and [[Democratic Progressive Party]] (DPP) along with the majority of the people in Taiwan, both native and overseas, use spelling and transcribe their legal names based on the Wade–Giles system, as well as the other aforementioned systems.{{Citation needed|date=November 2024}}

Wade–Giles writes ''-uei'' after ''k{{wg-apos}}'' and ''k'', otherwise ''-ui'': ''k{{wg-apos}}uei'', ''kuei'', ''hui'', ''shui'', ''ch{{wg-apos}}ui''.

It writes {{IPA|[-ɤ]}} as ''-o'' after ''k{{wg-apos}}'', ''k'' and ''h'', otherwise as ''-ê'': ''k{{wg-apos}}o'', ''ko'', ''ho'', ''shê'', ''ch{{wg-apos}}ê''. When {{IPA|[ɤ]}} forms a syllable on its own, it is written ''ê'' or ''o'' depending on the character.

Wade–Giles writes {{IPA|[-wo]}} as ''-uo'' after ''k{{wg-apos}}'', ''k'', ''h'' and ''sh'', otherwise as ''-o'': ''k{{wg-apos}}uo'', ''kuo'', ''huo'', ''shuo'', ''bo'', ''tso''. After ''ch{{wg-apos}}'', it is written ''ch{{wg-apos}}o'' or ''ch{{wg-apos}}uo'' depending on the character.

For ''-ih'' and ''-ŭ'', see [[#Syllabic consonants|below]].

Giles's ''[[A Chinese–English Dictionary]]'' also includes the finals ''-io'' (in ''yo'', ''chio'', ''ch{{wg-apos}}io'', ''hsio'', ''lio'' and ''nio'') and ''-üo'' (in ''chüo'', ''ch{{wg-apos}}üo'', ''hsüo'', ''lüo'' and ''nüo''), both of which are pronounced ''-üeh'' in modern [[Standard Chinese]]: ''yüeh'', ''chüeh'', ''ch{{wg-apos}}üeh'', ''hsüeh'', ''lüeh'' and ''nüeh''.

Wade–Giles writes the syllable {{IPA|[i]}} as ''i'' or ''yi'' depending on the character.

==System features==

===Consonants and initial symbols===
A feature of the Wade–Giles system is the representation of the [[Aspiration (phonetics)|unaspirated-aspirated]] [[stop consonant]] pairs using a character resembling an [[apostrophe]]. Thomas Wade and others used the [[spiritus asper]] ({{asper}} or {{wg-apos}}), borrowed from the [[polytonic orthography]] of the [[Ancient Greek]] language. [[Herbert Giles]] and others used a left (opening) curved single [[quotation mark]] (‘) for the same purpose. A third group used a plain [[apostrophe]] (').  The [[backtick]], and visually similar characters, are sometimes seen in various electronic documents using the system.

Examples using the spiritus asper: ''p'', ''p{{wg-apos}}'', ''t'', ''t{{wg-apos}}'', ''k'', ''k{{wg-apos}}'', ''ch'', ''ch{{wg-apos}}''. The use of this character preserves ''b'', ''d'', ''g'', and ''j'' for the romanization of [[varieties of Chinese|Chinese varieties]] containing [[voiced]] consonants, such as [[Shanghainese]] (which has a full set of voiced consonants) and [[Min Nan]] (Hō-ló-oē) whose century-old [[Pe̍h-ōe-jī]] (POJ, often called Missionary Romanization) is similar to Wade–Giles. POJ, [[Legge romanization]], [[Simplified Wade]], and [[EFEO Chinese transcription]] use the letter {{angbr|h}} instead of an apostrophe-like character to indicate aspiration. (This is similar to the obsolete [[International Phonetic Alphabet|IPA]] convention before the [[History of the International Phonetic Alphabet|revisions of the 1970s]]). The convention of an apostrophe-like character or {{angbr|h}} to denote aspiration is also found in romanizations of other Asian languages, such as [[McCune–Reischauer]] for [[Korean language|Korean]] and [[ISO 11940]] for [[Thai language|Thai]].

People unfamiliar with Wade–Giles often ignore the spiritus asper, sometimes omitting them when copying texts, unaware that they represent vital information. Hànyǔ Pīnyīn addresses this issue by employing the Latin letters customarily used for voiced stops, unneeded in Mandarin, to represent the unaspirated stops: ''b, p, d, t, g, k, j, q, zh, ch.''

Partly because of the popular omission of apostrophe-like characters, the four sounds represented in Hànyǔ Pīnyīn by ''j'', ''q'', ''zh'', and ''ch'' often all become ''ch'', including in many proper names. However, if the apostrophe-like characters are kept, the system reveals a symmetry that leaves no overlap:
* The non-[[retroflex]] ''ch'' (Pīnyīn ''j'') and ''ch{{wg-apos}}'' (Pīnyīn ''q'') are always before either ''ü'' or ''i'', but never ''ih''. 
* The [[retroflex]] ''ch'' (Pīnyīn ''zh'') and ''ch{{wg-apos}}'' (Pīnyīn ''ch'') are always before ''ih'', ''a'', ''ê'', ''e'', ''o'', or ''u''.

===Vowels and final symbols===

====Syllabic consonants====
Like [[Yale romanization of Mandarin|Yale]] and [[Mandarin Phonetic Symbols II]], Wade–Giles renders the two types of [[syllabic consonant]] ({{lang-zh|s=空韵|t=空韻}}; Wade–Giles: ''k{{wg-apos}}ung<sup>1</sup>-yün<sup>4</sup>''; [[Hànyǔ Pīnyīn]]: ''kōngyùn'') differently: 
* ''-ŭ'' is used after the [[sibilant]]s written in this position (and this position only) as ''tz'', ''tz{{wg-apos}}'' and ''ss'' (Pīnyīn ''z'', ''c'' and ''s'').
* ''-ih'' is used after the [[retroflex]] ''ch'', ''ch{{wg-apos}}'', ''sh'', and ''j'' (Pīnyīn ''zh'', ''ch'', ''sh'', and ''r'').
These finals are both written as ''-ih'' in [[Tongyòng Pinyin]], as ''-i'' in [[Hànyǔ Pīnyīn]] (hence distinguishable only by the initial from {{IPA|[i]}} as in ''li''), and as ''-y'' in [[Spelling in Gwoyeu Romatzyh|Gwoyeu Romatzyh]] and [[Simplified Wade]]. They are typically omitted in [[Bōpōmōfō|Zhùyīn (Bōpōmōfō)]].

====Vowel ''o'' ====
Final ''o'' in Wade–Giles has two pronunciations in modern Peking dialect: {{IPA|[wo]}} and {{IPA|[ɤ]}}.

What is pronounced in vernacular Peking dialect as a [[close-mid back unrounded vowel]] {{IPA|[ɤ]}} is written usually as ''ê'', but sometimes as ''o'', depending on historical pronunciation (at the time Wade–Giles was developed). Specifically, after velar initials ''k'', ''k{{wg-apos}}'' and ''h'' (and a historical ''ng'', which had been dropped by the time Wade–Giles was developed), ''o'' is used; for example, "哥" is ''ko<sup>1</sup>'' (Pīnyīn ''gē'') and "刻" is ''k{{wg-apos}}o<sup>4</sup>''<ref>''[[A Chinese–English Dictionary]]'', p. 761.</ref> (Pīnyīn ''kè''). In Peking dialect, ''o'' after velars (and what used to be ''ng'') have shifted to {{IPA|[ɤ]}}, thus they are written as ''ge'', ''ke'', ''he'' and ''e'' in Pīnyīn. When {{IPA|[ɤ]}} forms a syllable on its own, Wade–Giles writes ''ê'' or ''o'' depending on the character. In all other circumstances, it writes ''ê''.

What is pronounced in Peking dialect as {{IPA|[wo]}} is usually written as ''o'' in Wade–Giles, except for ''wo'', ''shuo'' (e.g. "說" ''shuo<sup>1</sup>'') and the three syllables of ''kuo'', ''k{{wg-apos}}uo'', and ''huo'' (as in 過, 霍, etc.), which contrast with ''ko'', ''k{{wg-apos}}o'', and ''ho'' that correspond to Pīnyīn ''ge'', ''ke'', and ''he''. This is because characters like 羅, 多, etc. (Wade–Giles: ''lo<sup>2</sup>'', ''to<sup>1</sup>''; Pīnyīn: ''luó'', ''duō'') did not originally carry the medial {{IPA|[w]}}. Peking dialect does not have phonemic contrast between ''o'' and ''-uo''/''wo'' (except in interjections when used alone) and a medial {{IPA|[w]}} is usually inserted in front of ''-o'' to form {{IPA|[wo]}}.

Zhùyīn and Pīnyīn write {{IPA|[wo]}} as ㄛ ''-o'' after ㄅ ''b'', ㄆ ''p'', ㄇ ''m'' and ㄈ ''f'', and as ㄨㄛ ''-uo'' after all other initials.

===Tones===
[[Standard Chinese phonology#Tones|Tones]] are indicated in Wade–Giles using superscript numbers (1–4) placed after the syllable. This contrasts with the use of diacritics to represent the tones in Pīnyīn. For example, the Pīnyīn ''qiàn'' (fourth tone) has the Wade–Giles equivalent ''ch{{wg-apos}}ien<sup>4</sup>''.

===Punctuation===
Wade–Giles uses [[hyphen]]s to separate all syllables within a word (whereas Pīnyīn separates syllables only in specially defined cases, using hyphens or closing (right) single quotation marks as appropriate).

If a syllable is not the first in a word, its first letter is not [[Majuscule|capitalized]], even if it is part of a [[proper noun]]. The use of apostrophe-like characters, hyphens, and capitalization is frequently not observed in place names and personal names. For example, the majority of [[overseas Taiwanese|overseas]] [[Taiwanese people]] write their [[given name]]s like "Tai Lun" or "Tai-Lun", whereas the Wade–Giles is actually "Tai-lun". (See also [[Chinese name]]s.)

*Wade–Giles chose the [[French language|French]]-like {{Grapheme|j}} (implying a sound like IPA's {{IPAblink|ʒ}}, as in '''''s''''' in English ''mea'''s'''ure'') to represent a Northern Mandarin pronunciation of what is represented as {{Grapheme|r}} in pinyin (Northern Mandarin {{IPAblink|ʐ}}/ Southern Mandarin {{IPAc-cmn|r}}; generally considered [[allophone]]s).
*''Ü'' (representing {{IPAslink|y}}) always has an [[Diaeresis (diacritic)|umlaut]] above, while pinyin only employs it in the cases of {{Transliteration|zh|pinyin|nü}}, ''{{Transliteration|zh|pinyin|nüe}}'', {{Transliteration|zh|pinyin|lü}}, ''{{Transliteration|zh|pinyin|lüe}}'' and ''{{Transliteration|zh|pinyin|lüan}}'', while leaving it out after ''j'', ''q'', ''x'' and ''y'' as a simplification because {{Grapheme|[[u]]}}/{{IPAblink|u}} cannot otherwise appear after those letters. (The vowel {{Grapheme|[[u]]}}/{{IPAblink|u}} can occur in those cases in pinyin where the diaeresis are indicated {{Grapheme|[[ü]]}}/{{IPAblink|y}} or {{IPAblink|ɥ}}; in which cases it serves to distinguish the [[front vowel]] {{IPAblink|y}} from the [[back vowel]] {{IPAblink|u}}. By contrast it is always present to mark the front vowel in Wade–Giles.) Because {{Transliteration|zh|pinyin|yü}} (as in {{Lang|zh-Hani|玉}} "jade") must have an umlaut in Wade–Giles, the umlaut-less {{Transliteration|zh|wadegile|yu}} in Wade–Giles is freed up for what corresponds to {{Transliteration|zh|pinyin|you}} ({{Lang|zh-Hani|{{linktext|有}}}} "have"/"[[Existential clause|there is]]") in Pinyin.
*The Pīnyīn cluster {{Grapheme|-ong}} is {{Grapheme|-ung}} in Wade–Giles, reflecting the pronunciation of {{IPAblink|ʊ}} as in English ''b'''oo'''k'' {{IPAc-en|b|U|k}}. (Compare ''[[Kung fu|kung<sup>1</sup>-fu]]'' to {{Transliteration|zh|pinyin|gōngfu}} as an example.)
*After a consonant, both Wade–Giles and Pīnyīn use {{Grapheme|-iu}} and {{Grapheme|-un}} instead of the complete syllables: {{Grapheme|-iou}} and {{Grapheme|-uên}}/{{Grapheme|-uen}}.

Note: In Hànyǔ Pīnyīn, the so-called neutral tone is written leaving the syllable with no diacritic mark at all. In Tongyòng Pinyin, a ring is written over the vowel.

==Adaptations==
There are several adaptations of Wade–Giles.

===''Mathews''===
The Romanization system used in the 1943 edition of ''[[Mathews' Chinese–English Dictionary]]'' differs from Wade–Giles in the following ways:<ref>''[[Mathews' Chinese–English Dictionary]]''.</ref>

*It uses the right apostrophe: <span style="font-family: serif; font-size:larger;">''p{{r-apos}}'', ''t{{r-apos}}'', ''k{{r-apos}}'', ''ch{{r-apos}}'', ''ts{{r-apos}}'', ''tz{{r-apos}}ŭ'';</span> while Wade–Giles uses the left apostrophe, similar to the aspiration [[diacritic]] used in the [[History of the International Phonetic Alphabet|International Phonetic Alphabet before the revisions of the 1970s]]: <span style="font-family: serif; font-size:larger;">''p{{wg-apos}}'', ''t{{wg-apos}}'', ''k{{wg-apos}}'', ''ch{{wg-apos}}'', ''ts{{wg-apos}}'', ''tz{{wg-apos}}ŭ''.</span>
*It consistently uses ''i'' for the syllable {{IPA|[i]}}, while Wade–Giles uses ''i'' or ''yi'' depending on the character.
*It uses ''o'' for the syllable {{IPA|[ɤ]}}, while Wade–Giles uses ''ê'' or ''o'' depending on the character.
*It offers the choice between ''ssŭ'' and ''szŭ'', while Wade–Giles requires ''ssŭ''.
*It does not use the spellings ''chio'', ''ch{{wg-apos}}io'', ''hsio'', ''yo'', replacing them with ''chüeh'', ''ch{{wg-apos}}üeh'', ''hsüeh'', ''yüeh'' in accordance with their modern pronunciations.
*It uses an underscored ''<sup>3</sup>'' to denote a second tone which comes from an original third tone, but only if the following syllable has the neutral tone and the [[Tone sandhi#Mandarin Chinese|tone sandhi]] is therefore not predictable: ''hsiao<u><sup>3</sup></u>•chieh''.
*It denotes the neutral tone by placing a dot (if the neutral tone is compulsory) or a circle (if the neutral tone is optional) before the syllable. The dot or circle replaces the hyphen.
