Gunung Merapi Update

Following from my last post, I did a bit of scrounging into the possibility of the prefix mer~ being of Sanskrit origin. I stumbled upon this site -

http://www.irfca.org/docs/place-names.html

and found the following entry -

"-mer Perhaps 'mountain' from Sanskrit 'meru'. E.g., Ajmer, Barmer, Jaisalmer. "

Granted, in this example, mer is a suffix, whereas in Merapi it is a prefix, but it's a good lead.
