IPA: /ˈsjuːdəˌnɪm/
KK: /ˈsuːdəˌnɪm/
A name that someone uses instead of their real name, often for writing or artistic purposes.
The author wrote under a pseudonym to keep their identity secret.
Pseudonym → It is formed from "pseudo-" (from Greek "pseudes", meaning false) and "onym" (from Greek "onuma", meaning name). The word "pseudonym" refers to a false name or an alias used by an author or individual.
Think of 'false' ('pseudo-') and 'name' ('onym') to remember that a pseudonym is a false name used by someone.
