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-Rundidialect 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.

Kirundi is one of the languages where Meeussen's rule, a rule describing a certain pattern of tonal change in Bantu languages, is active.

In 2020, the Rundi Academy was established to help standardize and promote Kirundi.
