Pseudonym

A pseudonym is a fictitious name used by a person, and particularly an author, to keep their identity concealed. Historically pseudonyms were more widely used by female authors and composers to make it more likely that their work would be published.

Etymological note: The noun pseudonym comes, through French, from the Greek adjective ψευδώνυμος (pseudōnumos), which means ‘under a false name’ or ‘falsely so called’ and is a compound of ψεῦδος (pseudos, ‘falsehood') and ὄνομα (onoma, 'name').
