Sembunadu.--The name, meaning the Pandya country, of a sub-division of Maravan. Semmadi.--A Telugu form of Sembadavan. Semman.--The Semmans are described, in the Madras Census Report, 1891, as "an insignificant caste of Tamil leather-workers, found only in the districts of Madura and Tinnevelly (and in the Pudukottai State). Though they have returned tailor and lime-burner as their occupations, the original occupation was undoubtedly leather-work. In the Tamil dictionaries Semman is explained as a leather-worker, and a few of them, living in out-of-the way villages, have returned shoe-making as their occupation. The Semmans are, in fact, a sub-division of the Paraiyans, and they must have been the original leather-workers of the Tamil tribes. The immigrant Chakkiliyans have, however, now taken their place." The Semmans are described, in the Madura Manual, as burning and selling lime for building purposes. In the Census Report, 1901, the caste is said to have "two hypergamous sub-divisions, Tondaman and Tolmestri, and men of the former take wives from the latter, but men of the latter may not marry girls of the former." Girls are married after puberty, and divorce and remarriage are freely allowed. As the caste is a polluting one, the members thereof are not allowed to use village wells, or enter caste Hindu temples. The caste title is Mestri. Sem Puli (red tiger).--A section of Kallan. Senaikkudaiyan.--The Senaikkudaiyans are betel vine (Piper Betel) cultivators and betel leaf sellers, who are found in large numbers in the Tinnevelly district, and to a smaller extent in other parts of the Tamil country. The original name of the caste is said to have been Elai (leaf) Vaniyan, for which the more high-sounding Senaikkudaiyan (owner of an army) or Senaittalavan (chief of an army) has been substituted. They also called themselves Kodikkal Pillaimar, or Pillaimars who cultivate betel gardens, and have adopted the title Pillai. The titles Muppan and Chetti are also borne by members of the caste.
