👉 Untouchability is a concept in Hinduism that refers to an individual's inability or unwillingness to be treated as equal with others, particularly by their caste. The term comes from the Sanskrit words "untu" (তী) and "tota" (তাট), which mean "to make unequal" and "to treat differently." In Hinduism, the concept of untouchability is central to understanding social hierarchies and discrimination against certain castes.
