History and etymology of foil

The word 'foil' as a verb, meaning to prevent the success or fulfillment of something, has its roots in Middle English and Old French. It can be traced back to the Old French word 'foil,' which meant 'to trample' or 'to tread on.' This Old French term itself came from the Latin word 'follis,' which referred to a leather bag or bellows. Over time, the sense of 'foil' evolved to signify the act of thwarting or hindering someone's plans or intentions, much like the notion of stepping on or trampling them. Thus, the etymology of the verb 'foil' reflects its historical connection to the idea of obstructing or impeding progress or success.
