Zulu ('zuːluː ), or isiZulu as an endonym, is a Southern Bantu language of the Nguni branch spoken in Southern Africa. It is the language of the Zulu people, with about 12 million native speakers, who primarily inhabit the province of KwaZulu-Natal of South Africa. Zulu is the most widely spoken home language in South Africa (24% of the population), and it is understood by over 50% of its population. It became one of South Africa's 11 official languages in 1994.
According to Ethnologue, it is the second-most-widely spoken of the Bantu languages, after Swahili. Like many other Bantu languages, it is written with the Latin alphabet.
In South African English, the language is often referred to in its native form, isiZulu.
Zulu migrant populations have taken it to adjacent regions, especially Zimbabwe, where the Northern Ndebele language (isiNdebele) is closely related to Zulu.
Xhosa, the predominant language in the Eastern Cape, is often considered mutually intelligible with Zulu, as is Northern Ndebele.
Maho (2009) lists four dialects: central KwaZulu-Natal Zulu, northern Transvaal Zulu, eastern coastal Qwabe, and western coastal Cele.
The Zulu, like Xhosa and other Nguni people, have lived in South Africa for hundreds of years. The Zulu language possesses several click sounds typical of Southern African languages, not found in the rest of Africa. The Nguni people have coexisted with other Southern tribes like the San and Khoi.
Zulu, like most indigenous Southern African languages, was not a written language until the arrival of missionaries from Europe, who documented the language using the Latin script.
The first grammar book of the Zulu language was published in Norway in 1850 by the Norwegian missionary Hans Schreuder. The first written document in Zulu was a Bible translation that appeared in 1883. In 1901, John Dube (1871–1946), a Zulu from Natal, created the Ohlange Institute, the first native educational institution in South Africa. He was also the author of Insila kaShaka, the first novel written in Zulu (1930).
