A new broom sweeps clean

1. New leadership injects energy.

Idioms and Phrases

A fresh leader or administration gets rid of the old and brings in new ideas and personnel. For example, Once he takes office, you can be sure the President will replace most of the people on the staff—a new broom sweeps clean. This term was already in John Heywood's 1546 proverb collection, was used figuratively by Shakespeare, and exists in many other languages as well.

Example Sentences

How picturesque and how true to life the well-worn adages, "A new broom sweeps clean," "A creaking door hangs long on its hinges," "One nail drives out another," as portrayed in the new-born diligence that, mayhap, will not last; in the career that drags along despite all probabilities of its survival; in the fickle heart and mind that lightly supplant old friends with new, or drop some hobby that a week ago seemed all-absorbing in favour of some other thing of no greater value, but possessing the attraction of novelty.
