Definition of the word sweep away

The phrase "sweep away" is a figurative expression that comes from the literal meaning of the word "sweep." In its primary sense, to sweep means to move a broom, brush, or other utensil over a surface, collecting loose dust, dirt, or debris in the process. This action, of clearing away unwanted particles, has given rise to a metaphorical usage of the word, where it is used to describe a forceful and decisive removal or elimination of something undesirable or objectionable. Thus, to say that something will "sweep away" something else is to suggest that it will remove, eradicate, or obliterate it completely and without hesitation. This usage is often seen in contexts where swift and thorough action is needed to overcome an obstacle or challenge, whether it be in the literal sense of cleaning up a mess or the metaphorical sense of resolving a problem.
