The origin and evolution of laterals in Proto-Naish

Abstract

This paper reconstructs Proto-Naish initials with lateral main consonants using data from three Naish languages: Lijiangba Naxi (LJ), Malimasa (MM), and Yongning Na (YN). The methodology of using conservative languages, such as Written Tibetan, Burmese, and rGyalrong, in interpreting sound correspondences is emphasized. At least five lateral initials should be reconstructed to Proto-Naish. Initial correspondences relevant to laterals are also discussed.
