When referring to an ordinary person, the phrase "man in the street" is often used. However, there are many other synonyms that can be used to describe this person. Some of these synonyms include the "average Joe," the "common man," and the "everyday person." These phrases all convey the idea of a person who is not famous or extraordinary, but rather someone who represents the majority of people. Other synonyms include "the public," "the masses," and "the crowd," all of which suggest a larger group of regular people. Ultimately, the choice of synonym will depend on the context and tone of the conversation.
