 There have been several attempts to clarify the linguistic situation in the southern and southwestern part of Bauchi State, Nigeria, of which the Polci cluster and Polci language are a part.In 1971, John Ballard, working with the Department of Linguistics and Nigerian Languages, University of Ibadan, did an extensive linguistic survey of the Nigerian Middle Belt published "Historical inferences from the linguistic geography of the Nigerian Middle Belt".As a result, it came to light that there was a narrow corridor occupied by the speakers of Chadic languages in the southwest of Bauchi.
