Rundi
Rundi is a term that can refer to several things, primarily related to the Rundi people and their language. The Rundi, also known as the Hutu and Tutsi, are the two largest ethnic groups in Burundi and Rwanda. They share a common language, Kirundi, and a similar culture, though historical social stratification has led to distinct identities. Kirundi is a Bantu language spoken by millions in East Africa. It is one of the official languages of Burundi, alongside French and English, and is also spoken in parts of Rwanda, Tanzania, and the Democratic Republic of Congo. The term "Rundi" can therefore be used as an adjective to describe things pertaining to Burundi, such as its people, culture, or language. In some contexts, it might also be used as a noun referring to a person from Burundi. The nuances of its usage depend heavily on the specific context in which it appears, but it almost always relates back to the nation of Burundi or its inhabitants.
