Banu language refers to a family of languages originating with and spoken by the Banu. Though all Banu share the same writing system, they speak many dialects, some of which are not mutually intelligible. Xenolinguists believe that this is partially due to their lack of both a central homeworld and a centralized government. The Banu have no formal name for their languages; instead, one who speaks Banu would say they “speak like Banu-folk” (yufu zuBanu, or yufu zo uBanu).
