Why were marks subtracted from one of my last ever essays for poor use of english because I chose to spell "rôle" with a circumflex in its rightful place?
(Knobbly) Because the examiner's wife had had an affair with Arsène Wenger. I'd say the circumflex is optional as the word becomes more and more part of the English (note capital) language. It's certainly not wrong.
(Dujon) Do you ever get snow? Must be pretty rare, I'd have thought. Good thunderstorm here this evening with one very close strike (guess 150 yd), the type that produces a crack and a ripping sound.
