कूर्म

Etymology
Given the unusual word structure and the semantic domain, probably a substrate loanword. Might be from the same family of words relating to "curved objects" with a ku- prefix as कुम्भ "water pot, pot"; कुण्ड or कुण्डी"water pot, pot"; कुम्बीर "crocodile"; कश्यप "tortoise, turtle"; कुष्माण्ड "pumpkin"; कूप "well"; कुब्ज "humpbacked"; and कलश "pitcher".

Noun

 * 1) a tortoise, turtle
 * 2) the earth considered as a tortoise swimming on the waters
 * 3) a particular figure or intertwining of the fingers (mudra)
 * 4) one of the outer winds of the body (causing the closing of the eyes)
 * 5)  Vishnu's second incarnation (descent in the form of a tortoise to support the mountain  at the churning of the ocean)
