Zulu (/ˈzuːluː/ ZOO-loo), or isiZulu as an endonym, is a Southern Bantu language of the Nguni branch spoken in, and indigenous to, Southern Africa. Nguni dialects are regional or social varieties of the Nguni language, distinguished by vocabulary, pronunciation, grammar, and other linguistic features. So, Zulu is one of the Nguni dialects which is spoken by the Zulu people, with about 13.56 million native speakers, who primarily inhabit the province of KwaZulu-Natal in South Africa. The word "KwaZulu-Natal" translates into English as "Home of the Zulu Nation is Natal". 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 12 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.
