here's some additions to this old thread...

xyresic - being as sharp as a razor [this one appears in the Grandiloquent Dictionary]
endochronic - related to internal time(?) [used by Asimov in a story title]
anophelosis - morbid state due to extreme frustration [from 'Pinky and the Brain' credits]

again, these are single sources which I have been unable to confirm...
