Whenever you find a word with an apostrophe, it's an "e" missing except for the fem. sing. definite article "la" before a word beginning by a vowel (l'eau-the water - l'ombre-the shadow/shade etc) and "si" (if) before "il": "s'il" = if he. Well, I studied English for 8 years and we didn't deal with friars' stuff either!
But thought it was only for two years, you know your name means "genius" don't you?
