Peace

Peace reduces to Three, a number tied to harmony between parts, fitting a word whose meaning is itself about resolved tension. Its reverse ordinal of 105 is more than triple its forward ordinal of 30, one of the largest such gaps among commonly studied words. The word traces to the Latin "pax," and entered English through Old French after the Norman Conquest, largely displacing the earlier Old English word for the same concept — one of many everyday English words with a French-derived double standing in for a native one that fell out of use.
