Mal: മാനന്തവാടി mānanthavādi
‘Great Bliss Village’
From Skt: maha, ‘great’, ‘abundant’; ānanda, ‘joy’, ‘bliss’; and Dra: paṭṭī/vāṭī, ‘settlement’, ‘town/village’; or Mal: mān, ‘deer’; eyyuka, ytu, ‘shoot an arrow’; and Dra: paṭṭī/vāṭī, ‘settlement’, ‘town/village’.
In one derivation the town is named after an ancient Jain temple on its outskirts (a.k.a. Mananthavady Shri Adinath Swamy Digambar Jain Temple).
In the other (slightly contrived) derivation the town marks the place where hunting commenced or took place, or where a specific arrow was shot.
