Kirundi, a Bantu language and one of the official languages of Burundi, holds profound cultural and linguistic significance in the heart of East Africa. With approximately 10 million native speakers, Kirundi plays a pivotal role in shaping the national identity of Burundi, fostering a sense of unity among its ethnically diverse population. Beyond its borders, Kirundi extends its linguistic embrace into neighbouring countries, notably Tanzania, where it is recognised as “Ikirundi” and is spoken by Burundian communities. This cross-border linguistic presence not only underscores the interconnectedness of communities but also contributes to the broader cultural exchange in the Great Lakes region. The tonal nuances and unique phonetics of Kirundi not only facilitate effective communication but also serve as a cultural repository, preserving the rich heritage and traditions of the Burundian people. In a global context, Kirundi exemplifies the diversity of languages in East Africa, playing a vital role in the region’s linguistic mosaic.
