Wonder is a word to wonder about. It contains a mixture of messages: something marvellous and miraculous, surprising, raising unanswerable questions about it self, making the observer wonder, even raising sceptical questions like, 'I wonder about that'. Miraculous and marvellous are clues; both words come from an ancient Indo-European root meaning simply to smile or to laugh. Anything wonderful is something to smile in the presence of, in admiration (which, by the way, comes from the same root, along with, of all telling words, 'mirror').
