Chandala (Sanskrit: चण्डाल) is a Sanskrit word for someone who deals with the disposal of corpses, and is a Hindu lower caste,[1] traditionally considered to be untouchable.[2][3]
Panchama means "of the fifth," and therefore outside the fourfold classical system of caste, or varna. Avarna, similarly means those outside the varna system. Chandala is a term referring to "unclean" castes and is used as a vlur in many parts of India.
