Chichewa
Chewa, also known as Nyanja, is a language of the Bantu language family. The noun class prefix chi- is used for languages, so the language is usually called Chichewa or Chinyanja. In Malawi, the name was officially changed from Chinyanja to Chichewa in 1968 at the insistence of President Hastings Kamuzu Banda (himself of the Chewa tribe), and this is still the name most commonly used in Malawi today. In Zambia, the language is generally known as Nyanja or Chinyanja 'language of the lake' (referring to Lake Malawi).
