English pseudonym

Back-formation from pseudonymous, from Latin pseudonymus (adjective), from Ancient Greek ψευδώνυμος (pseudṓnumos, adjective), from ψευδής (pseudḗs, “false”) +‎ ὄνυμα (ónuma, a dialectal form of ὄνομα (ónoma, “name”)) +‎ -ος (-os, adjective-forming suffix). Alternatively, borrowed from French pseudonyme (“fictitious name”, noun), coined in 1834 from pseud- +‎ -onyme (noun-forming suffix). By surface analysis, pseudo- +‎ -onym (noun-forming suffix).

     I doubt, indeed, whether I should not abandon the struggle altogether—leave this sad world of ordinary life for which I am so ill fitted, abandon the name of Cummins for some professional pseudonym, complete my self-effacement, and—a thing of tricks and tatters, of posing and pretence—go upon the stage.

   • 1928, H.P. Lovecraft, Supernatural Horror in Literature:

     The best example of its literary use so far are the German novel The Golem, by Gustav Meyrink, and the drama The Dybbuk, by the jewish writer using the pseudonym "Ansky".
