Brahui language, isolated member of the Dravidian languages that is spoken in south-central and western Pakistan. In the early 21st century Brahui was spoken by more than two million people.
Brahui’s isolation from the other Dravidian languages (all of which are spoken in eastern, central, and southern India) has resulted in heavy borrowing from surrounding non-Dravidian languages, including Balochi, Sindhi, and Persian. In part because it is not a written language, Brahui is being displaced by neighbouring languages. Many of its speakers are already bilingual.
