“Language-lovers know that there is a word for every fear. Are you afraid of wine? Then you have oenophobia. Tremulous about train travel? You suffer from siderodromophobia. Having misgivings about your mother-in-law is pentheraphobia, and being petrified of peanut butter sticking to the roof of your mouth is arachibutyrophobia. And then there’s Franklin Delano Roosevelt’s affliction, the fear of fear itself, or phobophobia.”
