Summary

Starting from an overview of the 10 major Chinese dialect groups, the article aims to provide a comprehensive introduction to endangered Chinese dialects. It delineates the causes and indicators of endangerment, describes the geographical distribution and speaking population of endangered dialects, and elucidates the influence of dominant languages on the linguistic traits of endangered dialects. The paper concludes with an exploration of ongoing preservation efforts dedicated to safeguarding endangered Chinese dialects.

The decrease in language use, influenced by the dominance of Mandarin and other dominant dialects, is identified as the primary cause of endangerment. The implementation of the language policy designating Mandarin as the standard national language to be used in education, administration, and public domains throughout the country has further contributed to this decline. Indicators of endangerment include decreased language use, bilingualism or multilingualism in dominant dialects, and limited domains of usage resulting in language shifting. The disruption of linguistic transmission from older to younger generations is another factor contributing to a diminishing population of speakers. Geographically, the largest cluster of endangered Chinese dialects is distributed at the junction of Guangdong, Guangxi, and Hunan provinces. These dialects have a small population of speakers, ranging from hundreds to tens of thousands.

Linguistically, the impact of dominant dialects on endangered dialects pertains to their phonological, lexical, and grammatical properties. While phonological instability displayed due to the influence of dominant dialects, certain stable features are identified, such as the retention or development of Middle Chinese voiced stops and affricates, as well as the preservation of sharp sounds. Lexical properties of endangered dialects are discussed in two aspects: (a) distinctive words in endangered dialects, including dialect-specific words, ancient Chinese words, and those related to folk culture; (b) word order variation between the endangered dialect and its dominant dialect. The erosion of grammatical properties is also noted, with endangered dialects borrowing features from dominant dialects.

The article emphasizes the importance of preserving linguistic diversity and protecting endangered Chinese dialects. The National Language Resources Protection Project in China is introduced as a comprehensive initiative aimed at surveying, collecting, and recording language resources. The project includes the publication of books, symposia, and an online platform showcasing audio and video recordings of endangered dialects. However, a comprehensive approach that includes explicit language policies and the establishment of dialect-promoting institutions are necessary for comprehensive protection.
