The original formulation included the Jukunoid and Kainji languages, and later the Dakoid languages; Jukunoid and Kainji now form a parent branch of Plateau called Central Nigerian (Platoid). (See Benue--Congo .) </P> <P> Defining features of the Plateau family have only been published in manuscript form (Blench 2008). Many of the languages have "fearsomely complex" phonologies that make comparison with poor data difficult . </P>
