αλὴθεια / Alithea.
a couple of points:
The word has remained the same into Modern Greek
The root verb is λανθάνω/lanthano=to escape notice/to make one forget/to lay hidden
as a result Alitheia, the Goddess of Truth, was always depicted as a naked, unassuming and plain looking woman. The Latin equivalent was nuda Veritas. Truth has nothing to hide and didn’t need all the adornments of the other gods.
The word you are looking for is:
Nuda Veritas is the derivation of the term “Naked Truth”.
There is absolutely no relation to λίθος/lithos=stone. Notice the η vs ι.
A similarly derived word is ληθαργία/lethargia=toiling under forgetfulness/stupor….lethargy.

the word is composed of the privative prefix α- and λήθη/lethe which means “forgetfulness/stupor”. So the αλήθεια means “without fault/stupor/hiding”
The Greek word for thief/robber/pirate is ληστής/listis which is derived from λανθάνω as well
