BaâÂÂShu Chinese (; Sichuanese Pinyin: Baùsuòyuó; ), or simply Shu Chinese (), also known as Old Sichuanese, is an extinct Chinese language formerly spoken in what is now Sichuan and Chongqing, China.
BaâÂÂShu Chinese was first described in the book Fangyan from the Western Han dynasty (206 BCEâÂÂ8 CE) and represented one of the earliest splits from Old Chinese. Unlike most extant varieties of Chinese, which stem from Middle Chinese, BaâÂÂShu diverged directly from Old Chinese, a feature it shares only with Min Chinese. However, BaâÂÂShu represents an even earlier split, as Min did not begin to diverge from Old Chinese until the Eastern Han (25âÂÂ220 CE) and Three Kingdoms period (220âÂÂ280 CE).
BaâÂÂShu Chinese started to disappear during the late Southern Song dynasty period due to the Mongol conquest of China, which resulted in a massacre throughout the Sichuan Basin. The language was supplanted by Southwestern Mandarin after settlement by people from other parts of China, mostly from present-day Hubei and Hunan.
Phonological aspects of BaâÂÂShu Chinese are preserved in the Minjiang dialect of Sichuanese Mandarin, which caused debate on whether the dialect is a variant of Southwestern Mandarin or a modern-day descendant of BaâÂÂShu.
Although the BaâÂÂShu language is extinct, some phonology features of rhymes can be found by researching the local literati and poets' use of rhymes in their works. Liu Xiaonan (2014) assumed that they wrote verses in Standard Chinese of the Song dynasty, but because their mother tongue was BaâÂÂShu, their verses rhymed in the BaâÂÂShu accent.
According to Liu's research, there is enough evidence to assume a significant number of coda mergers had taken place or were taking place in the BaâÂÂShu language during the Song dynasty:
BaâÂÂShu language had some unique words that scholars identified as possibly being influenced by the Old Shu language.
Notable speakers of the BaâÂÂShu language include the "Three Sà «s": (, sÃÂn sà «):
