Here is an interesting language from South Africa, which is similar to the Swazi language. It is called Zulu or isiZulu. Zulu is the language of the Zulu people with about 10 million speakers and the majority live in South Africa. In 1994, it became one of South Africa's eleven official languages. This language possesses several click sounds, which are typical of South African languages.
