I love it when something inexplicable becomes explicable. For the past few weeks I'd been haunted by the word "cabotinage"; at night or while I was walking home, it would just pop into my head for no particular reason, even though I had no idea what it meant or how to spell it. I finally managed to track it down in the OED, and a quick Google search revealed how it became lodged in my brain: it's one of the words from Spellbound.
