Usage

What is a pseudonym? A pseudonym is a false or fictitious name, especially one used by an author. When an author uses a pseudonym, it can also be called a pen name or a nom de plume. There are many reasons an author may choose to use a pseudonym instead of their own name, such as to avoid controversy or to create a persona. Many women authors throughout history have used a male or gender-neutral pseudonym to get their work published due to bias against women writers. A famous example is Mary Ann Evans, who used the pseudonym George Eliot. The word pseudonym can refer to a fake or false name used by anyone, not just writers. It’s typically used so a person can remain anonymous. In legal proceedings, the pseudonyms John Doe, Jane Doe, Richard Roe, and Jane Roe are used in​ when a person’s name is being kept anonymous. Such names can also be called anonyms. Example: A lot of people use pseudonyms when posting controversial opinions online.

Explanation

A pseudonym is a name that someone, often a writer, uses instead of their real name. The real name of Dr. Seuss was Theodore Seuss Geisel. Mark Twain was a pseudonym for the writer Samuel Clemens. A near synonym of pseudonym is pen name. Similarly, an allonym is the name of an important person in history that is taken by a writer as a pseudonym. Some of Shakespeare's plays might have been written by other writers using an allonym. If an actor uses a fake name, it is usually called a stage name. And there's no fancy work for nickname — it's just what your family and friends call you.
