Someone who is not important or well-known.
"The famous actor was forced to share the stage with a complete nobody from the local theater group."
In plain English: Nobody is a person who does not exist or is unknown to anyone else.
"Nobody answered the phone when I called earlier today."
Usage: Use "nobody" as a singular noun to refer to an insignificant person, often in phrases like "he's just nobody." Treat it grammatically as a third-person singular subject or object, for example, "Nobody is coming" or "I know nobody."
Not any person; the logical negation of somebody.
"Nobody showed up to the meeting because everyone else decided to take a day off."
Nobody comes from Middle English, where it was originally formed by combining "no" and "body" to mean "not a single person." The word entered modern usage as a straightforward compound phrase that has remained in use for centuries.
