The term 'Quick Refresher' can be broken down into two crossword solutions: NAP (3 letters) and CATNAP (6 letters). NAP stands for 'non-active period, ' which is a short break taken during the day to rest or relax. CATNAP, on the other hand, is a type of NAP that is usually taken during the day and lasts for a short period of time, usually between 15 minutes and an hour. Both of these terms are used to describe a quick break taken to refresh oneself.
