This appendix presents a comparative vocabulary dataset of nearly 1,000 lexical items drawn from 30 Mường dialects compiled by Dr. Nguyễn Văn Tài.

This dataset outlines the reconstruction of Vietnamese–Mường phonological systems. To demonstrate their structure and function, Dr. Nguyễn Văn Tài compiles a comparative list of one hundred lexical items. These entries represent sounds previously analyzed and are read across Mường (Bi dialect) and Vietnamese (Nghệ Tĩnh and Hanoi dialects), highlighting systematic correspondences.
