Why are there no OED entries for people, places, or events?
In common with most British dictionaries, the OED has never included entries for names, except where the name has acquired an extended or allusive sense: wellington boot, Honiton lace, Armageddon. The names of fictional characters or beings are only included if there is evidence of extended use: Svengali, munchkin. On the other hand, the familiarity of many eponyms has concealed their origin in personal names: boycott, mackintosh.
