Answer:
The caste system, as it actually works in India is called jati. The term jati appears in almost all Indian languages and is related to the idea of lineage or kinship group. There are perhaps more than 3000 jatis in India and there is no one all-Indian system of ranking them in order of status. Yet in each local area jati ranking exists and is very much related to purity and pollution. Each jati has some unique job, but not everyone in the jati performs it. Thus there are barbers who do not shave, carpenters who do not build, and Brahmins who do not act as priests. A jati is identified in a local setting by whom its members will accept food and water from and to which jatis its members will give food and water. People will try to marry their sons and daughters to members of their same jati and will give their major loyalty to their jati. A jati will usually be organized into a biradari (a brotherhood), and this organization carries out the business and oversees the working of the jati and has the power to exclude an offender from the jati.
