In the 1920s, the Rhodesian administration was faced with the challenge of preparing schoolbooks and other materials in the various languages and dialects and requested the recommendation of South African linguist Clement Doke.

Maho (2009) recognizes Korekore, Zezuru, Manyika, Karanga, and Ndau as distinct languages within the Shona cluster.
This inventory is quite common cross-linguistically, with similar systems occurring in Greek, Spanish, Tagalog, Swahili and Japanese.
