A 50-YEAR COMPARISON OF REGIONAL DIALECT VARIATION IN THE SUI LANGUAGE

This Sui dialect geography study conducted new fieldwork to examine changes among regional dialects across a time span of 50 years. The new field results were compared to an unpublished 1950s Sui dialect survey, Shuiyu Diaocha Baogao. The results provide new insights about this particular Tai-Kadai language and also new perspectives for the study of dialects and physical space in other small, rural indigenous communities across Southeast Asia.
