What is the origin of the idiom "sweep something under the rug" and when to use it?

The origin of the idiom "sweep something under the rug" can be traced back to the practice of physically sweeping dirt or debris under a rug to conceal it from view. The idiom figuratively refers to the act of hiding or covering up a problem, mistake, or unpleasant truth in order to avoid addressing or dealing with it openly. It can be used in discussions about politics, scandals, organizational misconduct, or even in interpersonal relationships where individuals choose to gloss over issues rather than confronting them head-on.
