Finally a Tamil one

What is the etymology of the word Thumbikkai as in the trunk of an elephant?

When man first saw the trunk, he realised that the trunk's function was something similar to that of a human' s hand. So he called the trunk "Tum Bhee Kai" and it become Thumbikkai.

I know it is a very bad one. Sorry folks for not producing good ones. The kadi manufacturing processor has not recovered even after the quizzes. It needs some time. Please be patient.
