Lusaka, in Lusaka Province, is the capital of Zambia. It is a cosmopolitan city that is home to approximately one in ten Zambians.
The residents of Lusaka come from all of Zambia's 70 or so tribes, and there are also small communities of Asians and Europeans. These different ethnic groups mostly get along extremely well together. The language of education and commerce is English, while the lingua franca on the street is 'Town Nyanja'. This language is a variant of the Nyanja spoken in Eastern Province (and neighbouring Malawi, where it is known as Chewa), but it is heavily mixed with expressions from other local languages and from English. Be warned that turning up in Lusaka speaking Nyanja/Chewa learned from books is like turning up in England speaking English learned from Shakespeare.
