Why “monomachia” is a great word
MONOMACHIA — [Noun] A formal duel or single combat between two individuals. From Latin monomachia, from Ancient Greek μονομαχία (monomakhía), from μόνος (mónos, "single, alone") + μάχομαι (mákhomai, "to fight"). Unlike "battle," which roils with the chaos of multitudes, or "duel," which carries the scent of specific historical honor codes, monomachia is the stark, technical skeleton of conflict reduced to its binary essence. It is Hector circling Achilles before the walls of Troy, two gladiators locked in the silence of the arena's gaze, or the entire weight of a war's grievance balanced on the point of a single spear—the world contracted to a fatal conversation between two wills.
