Editing Wade–Giles (section)

===''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.
