Another cool word, much beloved by H.P. Lovecraft is:
Now, I thought, after reading Lovecraft that it meant "formless" or "shapeless", but that's not quite it...
it apparently means "in the beginning stages" or "in a primitive or preliminary form".
For some reason Lovecraft found that horrifying. Of course he found all kinds of things horrifying that would probably not horrify the average person much at all. :-)
Like giant Antarctic penguins who shoot electric bolts out of their heads and utter the hideous cry "tek-e-li-li" at frequent intervals...
I kid you not. Lovecraft was one weird character.
