Only 47.8% of Sichuanese vocabulary is in common with the Beijing dialect on which Standard Chinese is based; Sichuanese shares more vocabulary with the Xiang and Gan varieties of Chinese, even though Sichuanese is usually classified as a dialect of Mandarin.[1]
The vocabulary of Sichuanese has three main origins: Bashu (or Ancient Sichuanese), Middle Chinese and the languages of the immigrants, including Proto-Mandarin from Hubei, Xiang, Gan and Hakka, which were brought to Sichuan during the Ming and Qing Dynasties. Recently, many loanwords have been introduced to Sichuanese from standard Mandarin and English. Meanwhile, new Sichuanese words are developing in large cities, such as Chengdu and Chongqing, which then spread at a dramatic speed through Sichuan.[2][3] "雄起" (xiong2qi3) (meaning "to cheer someone on") is a typical example of a novel Sichuanese word, equivalent to "加油" (jiāyóu) in standard Mandarin. The table below presents some common words in Sichuanese and their standard equivalents.
