Nande language
Nande, also known as "(Oru)Ndandi" and Yira, is a Bantu language spoken in the Democratic Republic of the Congo. The Nande of Congo and the Konjo people of Uganda are a single ethnic group, which they call Yira (Bayira). They trace their origins to the Ruwenzori Mountains between the two countries. The languages Nande and Konjo are close enough to be considered divergent dialects. Nande has a number of dialects of its own: Nande proper, Kumbule, Mate, Tangi, Sanza, Shu, Songola ("Songoora," Nyangala), Swaga / Kira (in Nande, all of these are prefixed with "eki-"). For the varieties of  this language known as Shu we are given the information that another language, "EkiShukaali" was formerly spoken by the women, the "AvaShukaali". This may be a specific reference to some kind of "secret jargon" into which the girls, and not boys, were initiated. Some of the Nande of Congo have a patron–vassal relationship with the Efé Pygmies.
