Besides referring to the language of the dominant people groups in Botswana, Setswana is the adjective used to describe the rich cultural traditions of the Batswana—whether construed as members of the Tswana ethnic groups or of all citizens of Botswana. In Botswana, most of the ethnic groups have different ways to greet one another, but for easy communication and connection, batswana use a three-way hand shake or just greet one another by saying "Dumelang" as a way of saying "hello" without physical contact. In community celebrations like Dikgafela or during marriage ceremonies, batswana women show excitement and happiness by the use of ululations as part of their culture.
