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 Mēstri.

Sem Puli (red tiger).—A section of Kallan.

Sēnaikkudaiyān.—The Sēnaikkudaiyāns 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) Vāniyan, for which the more high-sounding Sēnaikkudaiyān (owner of an army) or Sēnaittalavan (chief of an army) has been substituted. They also called themselves Kodikkāl 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.

It is recorded, in the Madras Census Report, 1901, that “the priests of the Sēnaikkudaiyāns are Vellālas, and occasionally Brāhmans. They do not wear the sacred thread. They burn their dead, and perform annual srāddhas (memorial services). In 1891, following the Tanjore Manual, they were wrongly classed with Vāniyans or oil-mongers, but they are superior to these in social position, and are even said to rank above Nāttukōttai Chettis. Yet it is stated that, in Tanjore, Paraiyans will not enter the Sēnaikkudaiyāns’ houses to carry away dead cattle, and ordinary barbers will not serve them, and food prepared by them will not be accepted even by barbers or washermen. Somewhat similar anomalies occur in the case of the Kammālas, and the explanation may be that these two castes belonged to the old left-hand faction, while the Pariyans, and the barbers and washermen belonged to the right-hand. Paraiyans similarly will not eat in the houses of Bēri Chettis, who were of the left-hand faction.”

Sēnapati.—A title, denoting commander-in-chief, said to be sold to Khōduras, and also occurring as a title of other Oriya castes, e.g., Kurumo and Ronguni. Among the Rongunis, the title is practically an exogamous sept. Sēnapati is further a name for Sālēs (Telugu weavers), the headman among whom is called Pedda (big) Sēnapati. The headman of the Sālāpu weavers, who do not intermarry with the Sālēs, is also styled Sēnapati. It is also a title of the Rāja of Sandūr.

Sendalai (red-headed man).—Returned as a sub-division of Konga Vellālas at times of census.

Sengundam (red dagger).—A synonym, connected with a caste legend, of Kaikōlan.

Seniga (Bengal gram: Cicer arietinum).—An exogamous sept of Mēdara and Pedakanti Kāpu.

Sēniyan.—The name Sēniyan is generally used to denote the Karna Sālē weavers, but at Conjeeveram it is applied to Canarese Dēvāngas. Elsewhere Canarese Dēvāngas belong to the left-hand section, but at Conjeeveram they are classed with the right-hand section. Like other Dēvāngas, the Conjeeveram Sēniyans have exogamous house-names and gōtras, which are interesting inasmuch as new names have been, in recent times, substituted for the original ones, e.g., Chandrasēkhara rishi, Nīlakanta rishi, Markandēya rishi. The Dēvāngas claim Markandēya as their ancestor. The old house-name Picchi Kaya (water-melon: Citrullus vulgaris) has been changed to Desimarada, and eating the melon is tabu. A list of the house-names and gōtras is kept by the headman for reference. The Conjeeveram Sēniyans are Lingāyats, but are not so strict as the Canarese Lingāyats. Jangams are respected, but rank after their own stone lingams. In the observance of death rites, a staunch Lingāyat should not bathe, and must partake of the food offered to the corpse. These customs are not observed by the Sēniyans. Until quite recently, a man might tie a tāli (marriage badge) secretly on a girl’s neck, with the consent of the headman and his relatives, and the girl could then be given in marriage to no other man. This custom is said to have been very common, especially in the case of a man’s maternal uncle’s or paternal aunt’s daughter. At Conjeeveram it was extended to girls not so related, and a caste council was held, at which an agreement was drawn up that the secret tāli-tying was forbidden, and, if performed, was not to be regarded as binding. The priest of the Conjeeveram Sēniyans is a Vellāla Pandāram, who is the head of the Tirugnāna Sambanda Murti mutt (religious institution) at Conjeeveram.

Sērvai.—Sērvai, meaning service, has been recorded as the title of Agamudaiyans and Valaiyans. Sērvaikāran or Sērvaigāran (captain or commander) is the title of Agamudaiyan, Ambalakāran, Kallan, Maravan, and Parivāram. It further occurs as the name for a headman among the Vallambans, and it has been adopted as a false caste name by some criminal Koravas in the south.
