debacle

Where does the word "debacle" come from? It comes from Latin baculum, passing through Old French and French before entering English (1848).

Debacle’s story begins in Latin: baculum meant “a stick.” A plain word for a stick or bar. By medieval, the word had taken hold in Old French as bacler. 'to bar', from the Latin word for a stick used to bolt a door. From there it passed into French as debacler by 1600s. Des- 'off' plus bacler 'to bar' - literally to unbar a river choked with ice. Within French, it grew into debacle by 1600s. The noun described the violent spring breakup of river ice, then any catastrophic collapse. It reached English by 1848 as debacle. Borrowed for a sudden, ignominious collapse or failure. Today, debacle means a sudden, ignominious failure or collapse.
