Origin of the Name Thisiayanvillai: This name consists of two words..Thisaiyan and Villai (Villa is a farm house in Latin and Vilai is a Farm land in Tamil). Apparently there is no record available to show how this village derived its name. Some probable ideas are listed here: 1. Kodumanal excavations near Erode, Tamil Nadu reveals personal names that include ‘Saba Magadhai Bammadhan,' ‘Saathan,' ‘Visaki,' ‘Siligan,' ‘Uranan' and ‘Tissan.' Tissan must be a famous name later transformed (maruvu in Tamil Grammar) into Thisaiyan.
2. “The Life of Gotama the Buddha", Tissa (directions?), also refers "for this Aiyan Eightfold Path and so forth.
“This Aiyan” also means “this konar or idaiyan” in Tamil. Two neighbouring villages of Thisaiya vilai are “Idaiyankudi” (A living place of Idaiyan or Knoar) is on the south-east and “Idaichivilai” (Farm of an Idaichi or Konar Lady) on the north-east. One can make an assumption that in the olden days Thisaiyanvilai may have been the farm land of Aiyar or Konar or Idaiyar. This is most probable for the simple reason that Late Ramakonar and his descendants including his son R. Sudalaikonar owned vast stretches of the farm lands from Selvamaruthoor to Thisaiyanvillai (for example the lands between the main road and Itamozhi Road up to the public library near the bus stand. Their descendants still own some remaining pieces of land (next to the public library). The public library was built on the land donated by Sri S. Chinna Arjuna Yadavar s/o Sudailaikonar. (refer the stone inscription on the walls of the Public Library).
3. Tissan (transformed into Thisaiyan) might have been derived come from one the religious texts of Hindus, Christians, Islam or Buddhists. "Tissan" Often refers "Lamb of God" in most religions.
There are many schools in Thisayanvilai. Daniel Thomas Group of Schools, Holy Redeemers higher secondary school, Sri Ramakrishna higher secondary school, samariya thuya yoovan higher secondary school, Jayarajesh matriculation, Malavidthya school, Hinthu primary school and Stella Mary's Girls High School are among them.
