Reconstruction
The Proto-Atayalic language was reconstructed by Taiwanese linguist Paul Jen-kuei Li in 1981. Proto-Atayalic had final voiced stops, which are preserved in the Mayrinax dialect of Cʔuliʔ Atayal. These voiced stops include *-b, *-d, *-g, and *-g'. However, they are now lost in many dialects of Atayal, Seediq, and also Pazeh (Blust 2009:615).
