The term "Bantu language" refers to a group of over 500 closely related languages spoken primarily in sub-Saharan Africa. These languages belong to the larger Niger-Congo language family and are characterized by similar grammatical structures and vocabulary. Some of the most widely spoken Bantu languages include Swahili, Zulu, and Xhosa. Bantu languages are notable for their use of noun classes, which categorize nouns into different groups. This classification affects verb conjugation and adjective agreement, making the languages unique in their structure. The spread of Bantu languages is linked to the historical migration of Bantu-speaking peoples across Africa.
