Pronunciation: [ʌntˌʌt͡ʃəbˈɪlɪti] (IPA) 
Untouchability, a social evil that has plagued the Indian society for centuries, is a term that refers to the practice of discriminating people based on their caste or social status. There are several synonyms for untouchability, including caste discrimination, caste-based discrimination, casteism, social apartheid, and social exclusion. These terms describe the same issue - the division of society into castes, where certain groups are considered inferior and subjected to discrimination and exclusion from social and economic opportunities. While India has made significant progress to eradicate untouchability, there is still a long way to go in promoting equality and social justice for all.
