The Khoisan languages are a group of languages spoken by the Khoisan people in southern Africa. They are known for their unique click consonants, which are sounds made by creating a suction in the mouth. These languages are primarily found in countries like Namibia, Botswana, and parts of South Africa. Khoisan languages are not a single language but rather a family of languages that include several distinct languages and dialects. They are among the oldest languages in the world, reflecting the rich cultural heritage of the Khoisan communities. Despite their historical significance, many Khoisan languages are endangered due to the decline in speakers.
