Jagham language

The Jagham language, Ejagham, also known as Ekoi, is an Ekoid language of Nigeria and Cameroon spoken by the Ekoi people. The E- in Ejagham represents the class prefix for "language", analogous to the Bantu ki- in KiSwahili

The Ekoi are one of several peoples who use Nsibidi ideographs, and may be the ones that created them.
