archimony n. anger about an injustice you only discovered long after the fact, after years have passed and everyone else has moved on, leaving you seething with an awkward and antiquated righteousness that you’re not sure what to do with, like a flywheel still spinning long after the engine is shut off. From archi-, earlier, primitive + acrimony, bitterness, animosity. Pronounced “ahr-kuh-moh-nee.”
