The last systematic study of varieties and sub-varieties of the Central Shona dialect continuum was that done by Clement Doke in 1930, so many sub-varieties are no longer functional and should be treated with caution. According to information from Ethnologue: • S14
Karanga (Chikaranga). Spoken in southern Zimbabwe, near
Masvingo. It is also mostly spoken in the Midlands province, most notably in Gutu, Masvingo, Mberengwa and Zvishavane districts. Some people refer it as Vhitori. :Subdialects: Duma, Jena, Mhari (Mari), Ngova, Venda (not the
Venda language), Govera. • S12
Zezuru (Chizezuru, Bazezuru, Bazuzura, Mazizuru, Vazezuru, Wazezuru). Spoken in
Mashonaland east and central Zimbabwe, near
Harare. The standard language. Standard Shona is based on Zezuru, and this has led to the decline and possible extinction of other related languages now referred to as "Shona dialects". :Subdialects: Shawasha, Gova, Mbire, Tsunga, Kachikwakwa, Harava, Nohwe, Njanja, Nobvu, Kwazvimba (Zvimba). • S11
Korekore (Northern Shona, Goba, Gova, Shangwe). Spoken in northern Zimbabwe,
Mvurwi,
Bindura,
Mt Darwin,
Guruve,
Chiweshe,
Centenary. :Subdialects: Gova, Tande, Tavara, Nyongwe, Pfunde, Shangwe. Languages with partial intelligibility with Central Shona, of which the speakers are considered to be ethnically Shona, are the S15
Ndau language, spoken in Mozambique and Zimbabwe, and the S13
Manyika language, spoken in eastern Zimbabwe, near Mutare specifically Chipinge. Ndau literacy material has been introduced into primary schools. Maho (2009) recognizes Korekore, Zezuru, Manyika, Karanga, and Ndau as distinct languages within the Shona cluster. ==Phonology==
