If you describe something as a shambles, it is a disorganized mess. The original meaning of ‘shamble’, however, was a bench. Years ago, butchers would set up their benches down the side of a street in order to sell their meat – in fact, many roads in England where this practice used to take place still retain the name of ‘Shambles Road’. The problem was that the butchers used to throw their offal and rotten meat in the street, which, as you can imagine, resulted in an awful mess. Hence the meaning of the word today!
