Sichuan
Languages

The Sichuanese once spoke their variety of Spoken Chinese called Ba-Shu Chinese, or Old Sichuanese before it became extinct during the Ming dynasty. Now most of them speak Sichuanese Mandarin. The Minjiang dialects are thought by some linguists to be a bona fide descendant of Old Sichuanese, but there is no conclusive evidence whether Minjiang dialects are derived from Old Sichuanese or Southwestern Mandarin.

The languages of Sichuan are primarily members of three subfamilies of the Sino-Tibetan languages.

The most widely used variety of Chinese spoken in Sichuan is Sichuanese, which is the lingua franca in Sichuan, Chongqing, and parts of the Tibet Autonomous Region. Although Sichuanese is generally classified as a dialect of Mandarin Chinese, it is highly divergent in phonology, vocabulary, and even grammar from Standard Chinese. The Minjiang dialect is especially difficult for speakers of other Mandarin dialects to understand.

Garzê Tibetan Autonomous Prefecture and Ngawa Tibetan and Qiang Autonomous Prefecture in western Sichuan are populated by Tibetans and Qiang people. Tibetans speak the Khams and Amdo Tibetan, which are Tibetic languages, as well as various Qiangic languages. The Qiang speak Qiangic languages and often Tibetic languages as well. The Yi people of Liangshan Yi Autonomous Prefecture in southern Sichuan speak the Nuosu language, which is one of the Lolo-Burmese languages; Yi is written using the Yi script, a syllabary standardized in 1974. The Southwest University for Nationalities has one of China's most prominent Tibetology departments and the Southwest Minorities Publishing House prints literature in minority languages. In the minority-inhabited regions of Sichuan, there is bilingual signage and public school instruction in non-Mandarin minority languages.
