This Zhuyin table is a complete listing of all Zhuyin (Bopomofo) syllables used in the Republic of China (Taiwan) as auxiliary to Chinese language studies while in Mainland China an adaptation of the Latin alphabet is used to represent Chinese phonemes in the Pinyin system.
This table indicates possible combinations of initials and finals in Standard Chinese, but does not indicate tones, which are equally important to the proper pronunciation.
There are differences between what syllables are listed in bopomofo tables and those that are listed in some pinyin tables, due to the standardisation differences of a few characters between the mainland standard Putonghua and the Taiwanese standard Guoyu.
For example, the variant sounds 挼 (ruá; ㄖㄨㄚˊ), 扽 (dèn; ㄉㄣˋ), 忒 (tēi; ㄊㄟ) are not used in the Taiwanese standard.
Likewise the variant sound 孿 (lüán; ㄌㄩㄢˊ) is not recognized in Putonghua, or it is folded into (luán; ㄌㄨㄢˊ).
