Balancing act using big vocabulary

Word collectors always have to tread a fine line between flattering their readers’ erudition and basking in their own, and [William F.] Buckley couldn't always keep his balance. He had a weakness for what the critic H. W. Fowler described as "Wardour Street words," after the street in Soho where Londoners used to shop for decorative bric-a-brac. He couldn't resist using catechize in place of question or grill, vaticination for forecast, estop for stop, and eo ipso for in and of itself.
