Written, published, or conducted under a secret or code name rather than a true identity.
From Greek 'kryptos' (hidden) + 'onym' (name) + '-ous' (characterized by). This term parallels 'anonymous' but specifically emphasizes that an alternate name, not anonymity, conceals the true identity.
Many historical authors published cryptonymous works because their real names couldn't be attached to controversial ideas—hiding behind a secret name let them say dangerous things their communities wouldn't allow!
