What does pseudonym mean?
A pseudonym is an assumed or invented name used instead of a person's real name. Writers commonly adopt one to create a distinct literary identity, while activists, researchers, and online commentators may use it to protect privacy or separate a professional voice from a personal identity. Unlike a simple alias, which may be an additional genuine name, a pseudonym specifically implies concealment, assumption, or replacement of the real name. The term is generally neutral and formal, but its connotations vary with context: a pen name can suggest artistic experimentation, whereas anonymity in testimony or online discussion can signal protection, distrust, or deliberate distance. Learning the word gives writers and readers a precise term for an identity that is real in its effects even though it is not the person's legal name.

Where does pseudonym come from?
The word was formed in English from Greek pseúdēs, meaning “false,” and ónoma, meaning “name,” so its literal sense is “false name.” It entered English in the early nineteenth century, initially in literary contexts for an assumed authorial name. Related English words based on the same Greek element for “name” include synonym, autonym, heteronym, and anonymous.
