Why this word is great

ADAMANCY — [Noun] The quality or state of being unyielding and inflexible in purpose or opinion. Formed within English from the adjective 'adamant' (ultimately from Ancient Greek ἀδάμας (adámas, "unconquerable, diamond")) + the noun-forming suffix '-ancy'. Unlike "obduracy," which implies a calloused, moral insensibility, or "resoluteness," which suggests a praiseworthy firmness, adamancy is the bare mineral core of will, stripped of valuation. It is the cold, ungiving pressure of granite against a shovel blade, the unblinking stare of a cliff face against the sea, and the diamond's cold, brilliant lattice that will not be scratched—a testament to the terrible strength found in an absolute refusal to bend.

noun

The property of being adamant.“Knowing the stubbornness and adamancy of born-again Christians, they're more likely to write off Borhek off as "fallen," and accuse her of succumbing to the arguments of Satan.”
