Why “interbellum” is a great word
INTERBELLUM — [Noun] A period of suspension and uneasy peace between two major wars, most specifically the two decades separating the First and Second World Wars. Learned borrowing from Latin inter ("between") + bellum ("war"). Unlike the commonplace adjective "interwar" or the culturally freighted "antebellum," which gazes backward to a lost order, *interbellum* is a formal, self-contained noun for a specific and fragile interval. It evokes the tinny gaiety of a gramophone in a half-furnished flat, the rust growing on stockpiled artillery in a quiet field, and the brittle optimism of a League of Nations parchment—a collective breath held by history, knowing the exhalation will be fire.
