The Greek origin of pseudonym (and even of its parts) is pretty obvious: Greek pseudṓnymos “under a false name, falsely called” is a compound whose first element pseudo- “false, lying” is a combining form of pseûdos “a lie.” The second element -ṓnymos is a combining form deriving from the noun ónoma (Doric and Aeolic ónyma ) “name.”
The English noun appeared in the early 1800s, but the adjective pseudonymous was recorded more than a century earlier, in Edward Phillips’s 1706 dictionary New World of Words.
- Compare allonym (def. 1).
