Rigwe language
The Rigwe language, Nkarigwe, is a Plateau language of Nigeria spoken by the Irigwe people mainly found in Bassa, [Plateau State|Bassa Local Government Area] of Plateau State.
Rigwe has highly complex phonology. 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.
