TheCentral Loloish languages, also known asCentral Ngwi, is a branch ofLoloish languages in Bradley (1997). It is not used in Lama's (2012) classification. Central Loloish is also not supported in Satterthwaite-Phillips' (2011) computational phylogenetic analysis of the Lolo-Burmese languages.[1]
Lama (2012) considers Central Loloish to beparaphyletic, and splits up Bradley's (1997) Central Loloish into the following independent branches of Loloish. TheLawu language group has been added from Yang (2012)[2] and Hsiu (2017).[3]
Pelkey (2011:367) lists the following as Central Ngwi innovations.
Proto-Ngwi tone categories 1 and 2: tone splitting that is widespread
Proto-Ngwi tone category 2 splits to *glottal-prefixed initials (higher-pitched reflexes) and *non-glottal-prefixed initials (lower-pitched reflexes; with a subsequent flip-flop in Lahu)
Proto-Ngwi tone category L prefixed stop initials > high/rising pitch reflexes
Family group classifiers paradigmatized with disyllabic forms, vowel leveling, and other systemic changes
Burmic extensive paradigm is moderately grammaticalized; more than Southern Ngwi, but fewer than Northern Ngwi
