pariah: [17] Now a general term for an ‘outcast’, pariah came into English from the caste system of southern India. It originally denoted a member of the largest of the lower castes, which was named in Tamil paraiyan. This meant literally ‘drummer’ (it was a derivative of parai ‘large festival drum’), a reference to the hereditary role of the paraiyar (plural) as drummers in festival parades.
