Background

No full reconstruction of Proto-Kra–Dai has been published to date, although tentative reconstructions of many Proto-Kra–Dai roots have been attempted from time to time. Some preliminary Proto-Kra–Dai forms have been reconstructed by Benedict (1975)[1] and Wu (2002). Wu (2002) presents a reconstruction of Proto-Kra–Dai phonemes, which is based on data from the Tai, Kam-Sui, Hlai, and Kra branches.[2]

Liang & Zhang (1996) propose a reconstruction of Proto-Kra–Dai (Chinese: 原始侗台语) initials and finals, using data from all Kra–Dai branches except for Kra and Jiamao.[3]

Phonology

Summarize
Perspective

Proto-Kra–Dai has the finals *-l and *-c, which have been lost in most present-day Kra–Dai languages.[4] It also has the final stops *-p, *-t, *-k and final nasals *-m, *-n, *-ŋ.[4]

Ostapirat (2023) proposes the following consonant inventory for Proto-Kra–Dai, which is relatively simple compared to that of Proto-Tai and other lower-level reconstructions.[5]

Norquest (2020) proposes the preglottalized sonorants *ʔb, *ʔd, *ʔɖ, *ʔɟ for Proto-Kra–Dai, as part of a four-way phonation distinction in Kra-Dai sonorants consisting of preaspirated, voiceless, plain, and preglottalized sonorants. Norquest (2020) also reconstructs velarized initial consonants (*Cˠ-) in Proto-Kra–Dai.[6]

Below is a table of Proto-Kra–Dai pre-syllables and their developments as proposed by Norquest (2020).[6]

Ostapirat (2023) considers many Proto-Tai spirants and rhotics to have developed from the intervocalic lenition of Proto-Kra–Dai medial obstruents. Voicing in the Proto-Tai initial is determined by the voicing of the preceding consonant in the Proto-Kra–Dai form.[5]

Ostapirat (2018, 2023)

Weera Ostapirat (2018a)[7] reconstructs disyllabic forms for Proto-Kra–Dai, rather than sesquisyllabic or purely monosyllabic forms. His Proto-Kra–Dai reconstructions also contains the finals */-c/ and */-l/.[8] Ostapirat (2018b:113)[9] lists the following of his own Proto-Kra–Dai reconstructions.

Notes:

  • */K-/: either /k-/ or /q-/
  • */C-/: unspecified consonant
  • */T-/ and */N-/ are distinct from */t-/ and */n-/.

Lower-level reconstructions

Note that like Jiamao, Proto-Be does not distinguish between tone categories B and C, but rather only has an X category, which Chen (2018) names as tone category BC.[11]
