  History
  Recoil came into English from Old French reculer ‘move back’, and first meant ‘drive or force back’ or ‘retreat’. The -coil part comes from Latin culus, which means ‘buttocks, bottom’: this gave rise to the French word cul, the source of cul-de-sac (literally ‘bottom of a sack’) and culottes.
