Castes and Tribes of Southern India/Kādu
Kādu.—Kādu or Kāttu, meaning wild or jungle, has been recorded as a division of Golla, Irula, Korava, Kurumba, and Tōttiyan. Kādu also occurs as an exogamous sept or gōtra of the Kurnis. Kādu Konkani is stated, in the Madras Census Report, 1901, to mean the bastard Konkanis, as opposed to the Gōd or pure Konkanis. Kāttu Marāthi is a synonym for the bird-catching Kuruvikarans. In the Malabar Wynaad, the jungle Kurumbas are known as Kāttu Nāyakan.
