Question

what do you understand by the term untouchablity

Answer 1

Untouchability is the social-religious practice of ostracizing a minority group by segregating them from the mainstream by social custom or legal mandate. The excluded group could be one that did not accept the norms of the excluding group and historically included foreigners, house workers, nomadic tribes, law-breakers and criminals and those suffering from a contagious disease. This exclusion was a method of punishing law-breakers and also protected traditional societies against contagion from strangers and the infected. A member of the excluded group is known as an Untouchable. The term is commonly associated with treatment of the Dalit communities, who are considered "polluting" among the people of South Asia, but the term has been used for other groups as well, such as the Burakumin of Japan, Cagots in Europe, or the Al-Akhdam in Yemen. Untouchability has been made illegal in post-independence India, and Dalits substantially empowered, although some prejudice against them continues, especially in rural pockets dominated by certain other backward caste groups.
