Nigbo language
Nigbo is an extinct Plateau language of Nigeria. It was spoken near Agameti on the Fadan Karshi-Wamba road near Sanga LGA, Kaduna State. The language, listed in Blench and, is not reported in Ethnologue or Glottolog. It is presumably an Alumic language based on its proximity to Akpondu, a language closely related to Alumu and Tesu.
The extinct undocumented languages Akpondu and Babur were also spoken in nearby villages of Nigbo and Babur, respectively.
