Etymology: Ancient Greek speakers built this word from "pseudḗs", meaning "false", and "ónoma", meaning "name", so "pseudṓnumos" literally meant "having a false name." Latin took it over as "pseudōnymus", and English later adopted the adjective form, which is why the word carries the same sense of a borrowed or invented name that it had in Greek. The word's core parts are plain: "pseud-" comes from the Greek for "false," and "-nym" from the Greek for "name," which also appears in words like "synonym" and "antonym." The ending "-ous" entered English through Old French from Latin "-osus," a suffix that turns a noun into an adjective meaning "full of" or "having" the quality named. A pseudonymous author is therefore one who has, in effect, a false name.

Synonyms: alias, pen-name
