Irigwe
Rigwe language
Plateau language of Nigeria
The Rigwe language, Nkarigwe, is a Plateau language of Nigeria spoken by the Irigwe people mainly found in Bassa Local Government Area of Plateau State.[3][4]
Rigwe has highly complex phonology.[5] The presence of the lateral fricative /ɬ/ in Rigwe, unusual among Plateau languages, suggests that there used to be West Chadic languages in the area with this phoneme.[6]
