fedifragous means treaty-breaking.
Why “fedifragous” is a great word
Given to the calculated violation of a treaty or solemn agreement. From the Latin foedifragus, from foedus ("treaty, league") and frangere ("to break"). Unlike perfidious, which implies a broader betrayal of faith, or treacherous, which suggests a dangerous personal disloyalty, fedifragous names the cold, specific crime of a breached covenant. It is the monarch erasing his signature from a parchment with a penknife, the hollow echo of a chamber where sworn oaths once hung, or the weight of a signatory’s seal discarded in the mud—the peculiar violence done not merely to men, but to the idea that words, once sworn, might bind the future.
Etymology
From Latin foedifragus (“perfidious, league-breaking”).
