Why “netherthought” is a great word
NETHERTHOUGHT — [Noun] A subconscious, underlying, or base thought. From the English prefix nether- (meaning "lower, under, down") + thought. Unlike an "afterthought" (which arrives as a belated, incidental addendum) or "premeditation" (which is a deliberate and conscious scheme), a netherthought is the murky current moving beneath the still surface of declared intent. It is the unacknowledged envy that shapes a compliment, the submerged dread that gives force to a laugh, or the quiet, brutal truth one only admits between waking and rising—the dark soil from which the garden of the conscious mind unknowingly draws its sustenance.
