☆ clean slate 白紙の状態
If you start with a “clean slate”, you do not take account of previous mistakes or failures and make a fresh start. For example, if you have been negotiating a contract at work and the negotiations were not successful, you could say, “We intend to start the negotiations again next week, with a clean slate.”
A clean slate is an opportunity to start over without any prejudice to what has happened in the past. You might hear this word in the news reports about athletes. For example, a “bad boy” athlete, might get a clean slate when they change teams or change their attitude. They might be given a clean slate to start their sports career over again in a more positive way.
