A cleverman is a traditional healer and keeper of culture in many Aboriginal cultures of Australia. The roles, terms for, and abilities of a cleverman vary between different Aboriginal nations. Some clevermen heal bodily injuries and illnesses, while others heal spiritual ailments. They heal using plants, songs, and spiritual knowledge. Exceptionally powerful clevermen are believed to have magical powers and may heal both physical and spiritual ailments. Some sources also refer to clevermen having the ability to kill using magic, although this may be illegal within the culture or a separate form of harmful 'sorcery' from that used by cleverman healers. Clevermen also serve as cultural keepers and are experts in stories and spiritual beliefs. They have a strong understanding of sacred places and lore and a deep connection to the Dreaming. Clevermen may be men or women, depending on the culture.
