Hapax Legomenon
ἅπαξ λεγόμενον
autoceratically
James Joyce, Ulysses (1922)
Context
Appears in the Cyclops episode. Joyce coins and deploys this word exactly once in over 260,000 words of text, blending 'autocratically' with 'keratin' (horn), punning on the one-eyed, horn-like authority of the Citizen.
Scholarly debate
Joyce scholars disagree on whether this is a deliberate portmanteau (autocratic + horned, matching the Cyclops motif) or a typographical eccentricity that survived editing. The Gabler edition retains it.
