The word "mob" is often associated with unruly groups of people. However, there are several synonyms that can be used to describe such a group. These include "crowd," "throng," "horde," "gang," "pack," "herd," "swarm," "mass," and "assembly." Each of these words conveys a slightly different connotation, from a large group of people gathered for a specific purpose (assembly) to a group of people with a common criminal purpose (gang). It is important to choose the right synonym when describing a group of people to accurately convey their purpose and behavior.
