A new broom sweeps

A classic idiom!

"A new broom sweeps clean" is a common English expression that means that a new person or thing, especially one that is inexperienced or untested, is likely to make a thorough and effective effort to correct or improve something that has been neglected or poorly done in the past.

The phrase is thought to have originated from the idea that a new broom, being unused and unbroken, is more effective at sweeping away dirt and dust than an old broom that has become worn out and less effective.

In a broader sense, the phrase is often used to describe a situation where someone or something new comes along and makes significant improvements or changes, often by bringing a fresh perspective or approach.

For example:

• "The new manager is a new broom, and she's already made some significant changes to the company's operations."
• "The new teacher is a new broom, and she's really helped to improve the students' grades and behavior."

Overall, "a new broom sweeps clean" is a phrase that suggests that new beginnings and fresh starts can often bring about positive change and improvement.
