Chumburung language
Chumburung is a Guang language spoken by 69,000 persons, mostly Chumburu by tribe and living in the Kingdom of Chumburung at both sides of the southwestern leg of Lake Volta in Ghana.
3,000 of these speak the Yeji dialect, which is quite divergent: no closer to Chumburung proper than Kplang or Krache are.
