Usage
What does pseudonymous mean? Pseudonymous means having, using, or written under a pseudonym—a false or fictitious name, especially one used by an author. The word is often used to describe a person who uses a pseudonym, as in the pseudonymous artist, or something attributed to a false name, as in her pseudonymous novels. 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 publish pseudonymously instead of under 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 pseudonymous titles John Doe, Jane Doe, Richard Roe, and Jane Roe are used in cases when a person’s name is being kept anonymous. Such names can also be called anonyms. Example: It’s sometimes hard to tell whether pseudonymous posts are published by bots or real people.
