This articlepossibly containsoriginal research. No sources use the term "Sichuanese Pinyin" (in English or Chinese), there's no evidence of any use outside of a handful of dictionaries, and the systems used by those dictionaries differ anyway, so it's not clear that the concept of "Sichuanese Pinyin" actually exists outside of Wikipedia (and the sites which have used it as a source). Pleaseimprove it byverifying the claims made and addinginline citations. Statements consisting only of original research should be removed.(May 2024) (Learn how and when to remove this message)

Sichuanese Pinyin (Si⁴cuan¹hua⁴ Pin¹yin¹;simplified Chinese:四川话拼音;traditional Chinese:四川話拼音;pinyin:Sìchuānhuà pīnyīn), is aromanization system specifically designed for theChengdu dialect ofSichuanese. It is mostly used in selected Sichuanese dictionaries, such as theSichuan Dialect Dictionary,^[1]Sichuan Dialect's Vocabulary Explanation,^[2] and theChengdu Dialect Dictionary.^[3] Sichuanese Pinyin is based onHanyu Pinyin, the onlyChinese romanization system officially instructed within thePeople's Republic of China, for convenience amongst users. However, Hanyu Pinyin is unable to match the phonology of Sichuanese with complete precision, especially in the case for theMinjiang dialect, as there are many differences between Sichuanese andStandard Chinese in phonology.

The Sichuanese Pinyin system uses superscript numbers to mark the four tones of Chengdu dialect. The number is placed on the top right corner of every syllable, where "1" stands for the first tone, "2" stands for the second tone, and so forth.

The rules of Sichuanese Pinyin are based on those of Hanyu Pinyin, with some slight modifications:

• When the final-ong has a zero-initial, it is writtenong (as opposed to Hanyu Pinyinweng).
• As in Hanyu Pinyin,ü is writtenu when paired with the series ofalveolo-palatal initials (j-,q- andx-); however, the rule is not extended to the additional memberȵ- (e.g.女 ȵü³).
