Bambara language
The "dyula" speak the Dioula language or "Julakan", which is included in the group of closely interrelated Manding languages that are spoken by various ethnic groups spread across Western Africa. Dioula is most closely related to the Bambara language (the most widely spoken language in Mali), in a manner similar to the relation between American English and British English. It is probably the most used language for trade in West Africa.
