Pseudonym is from French pseudonyme, from Ancient Greek pseudōnymos ('falsely named'), from pseudēs ('false') + onyma (Aeolic form of onoma, 'name'). Important recorded forms include pseudōnymos (Ancient Greek), onoma (Ancient Greek), and *h₁nómn̥ (Proto-Indo-European). Morphologically, the word preserves a built structure whose named elements carry the historical sense into English. The modern sense remains close to that composition, with the parts narrowing into a single lexical item. In current use it covers a fictitious name used by an author in place of their real one. The wider family includes derived forms such as pseudonymous and pseudonymity and related words such as anonym, synonym, and antonym.
