Jatis (the word literally means "births") comprise the subcastes found within the four major castes, or varnas, of the Indiancaste system. Each jati typically has an association with a traditional job function in Hindu society, although religious beliefs (e.g. Sri Vaishnavism or Veera Saivism) or linguistic groupings define some jatis. A person's surname typically reflects a jati association: thus Gandhi = greengrocer, Dhobi = washerman, Srivastava = military scribe, etc. In any given location in India 500 or more jatis may co-exist, although the exact composition will differ from district to district.

It is believed that the jati system ossified from an original occupation-based classification into a hereditary classification with attendant rules forbidding marriage between jatis.
Jati comes from the root jan meaning "to beget" or "to produce" and is used to denote origin and the group or class which something belongs to.
In terms of caste, jati is the social stratum in which one is born.
The actual rank of a jati is not so much due to social and occupational practices of the members but is more because of the purity of the souls of the members resulting from their previous lives.
Jati is not caste, but became so under colonial rule (Dirks did a lot of good research on this).
Jati means real working community of birth, marriages, of profession, culture and religion (closer to the widely (mis)understood meaning of caste; varna, however, means the social rank, status, order (closer to class).
Ignoring the conceptual distinction between “jati” and “varna” (which is sometimes deliberate and ideologically motivated) doesn’t help either a deeper understanding of the origins of the system or serious efforts to combat the distortions that have crept in.
