The Dravidian-speaking Kurukh people in Ranchi suburbs have adopted a creolized dialect of Kherwarian Mundari called Keraʔ Mundari. Its verbal morphology is less complex than an average Austroasiatic Kherwarian language.
Santali is characterized by a split into at least a northern and southern dialect sphere, with slightly different sets of phonemes: Southern Santali has six phonemic vowels, in contrast with eight or nine in Northern Santali, different lexical items, and to a certain degree, variable morphology. Santali is recognized by linguists as being phonologically conservative within the Munda branch. Unlike many Munda languages that had their vowel systems restructured and shrunk to five such as Mundari, Ho, and Kharia, Santali retains a larger vowel system of eight phonemic cardinal vowels, which is very unusual in the South Asian linguistic area. The language also uses vowel harmony processes in morphology and expressives similar to Ho and Mundari. Morphosyntactically, Santali, together with Sora, are considered less restructured than other Munda languages, having less influence from Indo-Aryan and Dravidian languages. Clause structure is topic-prominent by default.
