Kirundi

Kirundi (), officially known as Ikirundi (also known as Rundi), is a Bantu language and the national language of Burundi. It is mutually intelligible with Kinyarwanda, the national language of Rwanda, and the two form parts of the Rwanda-Rundi dialect continuum spoken in Burundi, Rwanda, Tanzania, Democratic Republic of Congo, Uganda, and Kenya.

Kirundi is natively spoken by the Hutu (including the Bakiga), Tutsi, Twa, and the Hima people; other related ethnicities have also adopted Kirundi as their mother tongue. Neighbouring dialects of Kirundi are mutually intelligible with Ha, a language spoken in western Tanzania.
