Editing Wade–Giles (section)

===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.
