Word that means “sourceless”

Question

I'm looking for a word that means without a source but that is a little shorter and simple than sourceless. Coulnd't find any on Thesaurus.

Any suggestions?

Answer 1

here is a suggestion:

aseity - the quality or state of being self-derived or self-originated

link - http://en.m.wikipedia.org/wiki/Aseity

or try groundless or just source-less if it gets complicated.

Answer 2

There are words like groundless and unfounded that basically mean that you don't have supporting facts but not exactly the same as sourceless.

Answer 3

In the absence of more context, I suggest "self-manifested".

Answer 4

I'm a bit prejudiced to the concept of fons et origo but a hapax legomenon is a term of which only one instance of use is recorded and anything without an origin is cryptogenic or a term that refers to something of obscure or unknown origin.
