It is spoken by the Wadiyara people, who originate from Wadiyar in Gujarat; many of whom are thought to have migrated to Sindh in the early twentieth century, following the onset of famine.
Generally, the close back monophthong is the most regular; but this is also uncommon in word-initial contexts.
Wadiyara Koli possesses 38 distinct phonemic consonants, which entail seven places and eight manners of articulation.
Wadiyara Koli's 16 plosive consonants have four places of articulation: the bilabial, alveolar, retroflex, and velar.
Wadiyari possesses four discernible nasal phonemes; the bilabial, the alveolar, the retroflex, and the velar; the latter two are restricted.
Most of the time it is followed by the voiced velar plosive, but it can also be followed by the lateral retroflex, as well as occurring independently.
Unusually for Indo-Aryan languages, four distinct phonemic fricatives are recorded in Wadiyari; contrasting at three places of articulation: the alveolar, the post-alveolar, and the glottal.
