Tamilian parents usually follow the naming trends for their babies as Initial (village name) then Initial (Father's name) followed by first name and then caste name.
Tamilian baby names are generally patronymic, which means that the first name of one generation becomes the second name of the next generation. In various cases, the father's name appears as an initial and thus the first name may be presented as a second name. After marriage, Tamilian women adopt their husband's first name as their second name. Tamilian parents gave up the tradition of using caste name as their surname after the Dravidian movement. The naming ceremony known as “Thottil” ceremony is held after two weeks of baby’s birth. In this ceremony the family, close relatives, and friends gather and say the baby’s name to the new-born three times each.
