Etymology

From French débâcle, from débâcler (“to unbar; unleash”) from prefix dé- (“un-”) + bâcler (“to dash, bind, bar, block”) [perhaps from unattested Middle French and Old French bâcler, bacler (“to hold in place, prop a door or window open”)], from Vulgar Latin bacculare, from Latin baculum (“rod, staff used for support”), from Proto-Indo-European bak-. Also attested in Old French desbacler (“to clear a harbour by getting ships unloaded to make room for incoming ships with lading”) and in Occitan baclar (“to close”). The hypothesised derivation from Middle Dutch bakkelen (“to freeze artificially, lock in place”), a frequentative of bakken (“to stick, stick hard, glue together”) no longer seems likely due to the lack of attestation of bakkelen in Middle Dutch and by it having the limited meaning of "freeze superficially" in Dutch.
