A more thorough explanation:

nemo

Nemo means "no one" or "no man" in Latin. It is often used in Latin phrases, such as "nemo est supra leges" which means "no one is above the law."

• "Nemo was found guilty of the crime because there were no witnesses."
• "The company's policy is that nemo should be discriminated against based on their race or gender."

The examples show how nemo is used to refer to a person who is unknown or does not exist. In the first example, nemo refers to a person who was not present to witness the crime. In the second example, nemo refers to any person, regardless of their race or gender.
