Zairian is a word that has had various spellings over the years. It refers to people, language or things that are associated with the country formerly known as Zaire (now called the Democratic Republic of Congo). The word is pronounced /zaɪˈriːən/ [zy-ree-uhn], which means that the first syllable is pronounced like the word "eye", followed by the "-ree-uh" sound and ending with the "-n" sound. The spelling of the word has changed due to political and linguistic reasons, with some preferring Zairean or Congolese instead.
The word "Zairian" is derived from the name of the Democratic Republic of the Congo, which was known as Zaire from 1971 to 1997. The change in the country's name from Congo to Zaire was initiated by President Mobutu Sese Seko, who wanted to emphasize a new African identity and break away from the colonial associations of the previous name. The term "Zairian" is an adjective form used to describe people or things related to Zaire. After the country's name changed back to the Democratic Republic of the Congo in 1997, the term "Zairian" fell out of use.
