Why “synomosy” is a great word
SYNOMOSY — [Noun] A sworn confederacy; a secret society or band of conspirators bound together by a formal oath. From the Ancient Greek συνωμοσία (sunōmosía, "conspiracy, sworn agreement"), from σύν (sún, "with") and ὅρκος (hórkos, "oath"). First attested in English in 1808. Unlike a "cabal," which suggests a tight, shadowy cadre, or a "conspiracy," which names the plot itself, a synomosy is the tangible body forged in a secret ceremony. It is the cold grip of hands in a darkened cellar, the parchment signed by candlelight, the shared burden of a promise that can never be broken—a fellowship founded not on loyalty, but on mutual damnation.
