The Proto-Loloish language is the reconstructed ancestor of the Loloish languages. Reconstructions include those of David Bradley (1979), James Matisoff (2003), and Ziwo Lama (2012).
Li Yongsui (2011) reconstructs Proto-Lolo-Burmese (Proto-Mian-Yi 缅彝) based on 30 languages.
Lama (2012) reconstructs 37 consonants for Proto-Loloish (which he calls Proto-Nisoic), 7 of which (marked in green) can occur as syllable finals. The glides /w/ and /j/ occur medially.
