Wade-Giles

Wade-Giles, sometimes abbreviated Wade, is a Romanization (phonetic notation and transliteration) system for the Chinese language based on the form of Mandarin used in Beijing. It developed from a system produced by Thomas Wade in the mid-19th century, and reached settled form with Herbert Giles's Chinese-English dictionary of 1912. It was the main system of transliteration in the English-speaking world for most of the 20th century, replacing the Nanjing-based romanization systems that had been common until late in the 19th century.

One symbol-multiple sounds

A common complaint about the Wade-Giles system is the representation of the unaspirated-aspirated stop consonant pairs using apostrophes: p, p', t, t', k, k', ch, ch'. However, the use of apostrophes preserves b, d, g, and j for the romanization of Chinese dialects containing voiced consonants, such as Shanghainese (which has a full set of voiced consonants) and Taiwanese (Hō-ló-oē) whose century-old Missionary Romanisation is similar to Wade-Giles.

On the other hand, people unfamiliar with the Wade-Giles often ignore the apostrophes, even so far as leaving them out when copying texts, unaware that they represented vital information. Hanyu Pinyin 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, zh/j, ch/q.

Partly because of the popular omission of the apostrophe, the four sounds represented in Hanyu Pinyin by j, q, zh, and ch all become ch in many literature and personal names. However, were the diacritics to be kept, the system reveals a symmetry that leaves no overlap:

• The non-retroflex ch (Pinyin j) and ch' (Pinyin q) are always before either i or ü.
• The retroflex ch (Pinyin zh) and ch' (Pinyin ch) are always before a, e, ih, o, or u.
