The Proto-Bahnaric vowel system: a new theory

This paper proposes a revised reconstruction of the Proto-Bahnaric vowel system, challenging previous models within Austroasiatic historical linguistics. Drawing on comparative data from Bahnaric languages, Sidwell identifies systematic correspondences that suggest a more complex vowel inventory than traditionally assumed. The new theory accounts for phonological developments and irregularities observed across subgroups, offering explanations for vowel shifts and mergers. The study emphasizes the role of internal reconstruction and typological plausibility in refining proto-language models. By reassessing foundational assumptions, the paper contributes to a deeper understanding of Bahnaric phonology and supports broader efforts to reconstruct Austroasiatic linguistic history with greater accuracy (AI generated abstract, Copilot)
