Goemai is an Afro-Asiatic (Chadic, West Chadic A) language spoken in the Plateau state of Central Nigeria by approximately 200,000 people. Its speakers refer to themselves and their language as 'Goemai'; in older linguistic, historical and ethnographical literature the term 'Ankwe' has been used to refer to the people.
