IPA: /ˈsjuː.dɪˌpɪɡ.ræf/
KK: /ˈsuːdɪˌpɪɡrəf/
A false or misleading piece of writing that is attributed to someone else, often used in a religious or literary context.
The ancient manuscript was considered a pseudepigraph because it was falsely attributed to a well-known author.
Pseudepigraph is formed from "pseudo-" (from Greek 'pseudes', meaning false) and "epigraph" (from Greek 'epigraphe', meaning inscription). The term refers to a work that is falsely attributed to an author, hence a false inscription of authorship.
Think of 'pseudo-' meaning false, and 'epigraph' meaning inscription — this helps you remember that a pseudepigraph is a false attribution of authorship.
