A recognised or important person, a celebrity.
"When that famous actor walked into the coffee shop, everybody stopped talking because they wanted to meet somebody special."
In plain English: Somebody is a person who you know or are talking about.
"Everybody in the room said they knew somebody who could help us fix the car."
Usage: Use somebody to refer to an influential figure or celebrity rather than just any unknown individual. This term often carries the implication of someone who commands attention due to their status in society.
Some unspecified person.
"I asked somebody to hold my bag while I looked for my keys, but they forgot when everyone left together."
The word somebody comes from Middle English, where it was formed by combining the words some and body. It originally meant an unspecified person, a meaning that remains the same in modern English.
