Social status
They were subjugated to untouchability and were known as "unseeable caste", as they were only allowed to travel at night, and some even obliged to drag a palmyra palm behind them. It is speculated that it served the purpose for either notify their whereabouts or for members from privileged castes to avoid their footprints.[3]
Etymology
Customs
They are in some regions considered to be a subcaste of the greater Vannar caste, and in other as an independent caste. One of the kuti (or clan) name of the Batticaloa Vannars is Thurumba Vannar. They are in Sri Lanka noted for performing laundry for members from the Sri Lankan Paraiyar, -Pallar, and Nalavar castes.[3] The Thurumbar had a reputation for being involved in sorcery, known in Tamil as sūniyam, and would use it to injure or kill other's for a fee.[3][7]
According to the archeologist Ponnambalam Ragupathy, they were earlier scavengers who later took to laundry.[8]
