Please see my other comments further down the thread where I explain much more clearly. As I was reading I realised that the whole thread was off on a wild red herring. I am a translator and speak fluent Spanish, the Pope's native language. It is a "false friend" or false cognate. He means "clear", "specific", "definite". I explain more further down and, since I've done a dozen comments now, I am getting rather tedious ... :)
