Breaking down the question
The command word is explain, and the object is the different forms of untouchability. This is a classificatory question worth ten marks: the examiner wants a structured typology of how untouchability manifests, not a general essay on caste. The word different forms is the organising cue — the answer should enumerate distinct modes clearly.
Untouchability must be grounded in its logic before its forms are listed. It rests on the notion of purity and pollution, by which contact with certain castes is held to defile the higher-caste person. A brief statement of this principle frames the typology and shows sociological understanding rather than mere description.
Given the mark weight, the answer should be compact and well-labelled, moving from traditional and overt forms to hidden and modern ones. For the wider treatment, see the note on untouchability, its forms and perspectives.
How to approach it
Open with a one-line definition anchored in the concept of purity and pollution, and note that untouchability was constitutionally abolished under Article 17 yet persists socially.
Organise the body as a clear typology. Move from spatial and residential exclusion, through commensal restrictions on food and water, to social and ceremonial exclusion from temples, wells and rituals, then to occupational stigma and, importantly, the hidden and modern forms that survive in cities and institutions.
Keep each form to a crisp sentence or two with a concrete example. Conclude by noting that untouchability has changed shape rather than disappeared, echoing Ambedkar's account of graded inequality.
Model answer
Untouchability is the practice by which certain castes, historically placed outside the fourfold varna order, are treated as ritually polluting, so that physical or even indirect contact with them is held to defile members of higher castes. It rests on the ideology of purity and pollution and, though abolished by Article 17 of the Constitution, it persists in varied forms.
The first is spatial and residential segregation. Dalit households were, and often still are, located on the outskirts of the village, separated from the main settlement, with restricted access to common land, streets and cremation grounds. Physical distance encodes ritual distance.
The second is commensal exclusion — restrictions surrounding food and water. So-called untouchables were barred from common wells and water sources, denied entry to tea stalls and eateries, or served in separate vessels, and could not share food with the higher castes. The idea that their touch pollutes water and food is central here.
The third is social and ceremonial exclusion. This includes denial of entry to temples, prohibition on participation in village festivals and public rituals, exclusion from priestly services, and bans on the use of common facilities. It extends to prohibitions on inter-dining and inter-marriage, and to humiliating norms of deference in dress, speech and posture before higher castes.
The fourth is occupational stigma. Untouchable castes were assigned the most polluting tasks — scavenging, leather work, disposal of dead animals and manual removal of human waste. The occupation itself became a marker of pollution, and manual scavenging survives as its most degrading form.
The fifth, and increasingly important, is hidden and modern untouchability. In towns and institutions overt exclusion may be muted, yet it reappears as discrimination in housing, refusal of rented accommodation to Dalits, segregation in mid-day meal seating in schools, bias in the workplace, and reluctance to enter inter-caste marriage. This subtle, deniable form shows the practice adapting to contexts where open discrimination is illegal.
B. R. Ambedkar understood these forms as expressions of a system of graded inequality, in which each layer of the hierarchy guards its status against those below. The forms have softened and gone partly underground under law, urbanisation and social movements, but untouchability has changed shape rather than ended, which is why constitutional abolition has had to be reinforced by continuing social reform and legal protection.
Examiner's perspective
At ten marks, the mark scheme rewards a clear typology over a discursive essay. Examiners look for distinct, well-labelled forms — spatial, commensal, ceremonial, occupational and modern or hidden — each illustrated in a line. A candidate who lists these crisply outperforms one who writes a general paragraph on caste discrimination.
The finishing touches that earn the top of the band are conceptual and evidential: anchoring the answer in purity and pollution, citing Article 17, invoking Ambedkar's graded inequality, and drawing attention to the persistence of hidden untouchability in modern institutions. That combination shows the candidate grasps untouchability as a living, mutating structure rather than a relic.
