Castes and Tribes of Southern India/Nāyinar
Nāyinar.— Nāyinar, Nāyanar, or Nainar, has been recorded as a section of Vellālas, who are thought to be descended from Jains who were converted to Hinduism, and as a title of Jains, Kaikōlans, Pallis, and Udaiyāns. Nāyanikulam occurs as a synonym of Bōya. The word Nāyinar is the same as Nāyaka, meaning lord or master, and the Saivite saints, being religious teachers, are so called, e.g., Sundara Mūrti Nāyanar.
