When groups that do not share a common language need to communicate, they develop what is called a pidgin language. These are usually based on the language of a colonising or trading power, but “Fanakolo” is a rare example of a pidgin language based on an indigenous language, Zulu. It is comprised of instructions and orders used between mineworkers and foremen from different regions in Southern Africa. In 1975 there were estimated to be several hundred thousand second-language speakers of Fanakolo. (https://bit.ly/2NaMngk)
